"Dr. Henderson and SonoVet have been a great asset to our practice and to my personal development as a practitioner. Among the most valuable services I can offer to anxious clients are pain free and non-invasive answers. Marty and SonoVet provide exactly those answers, time and time again, helping me and my clients make accurate, beneficial, and humane decisions. I've had a great education learning the depth and extent that quality ultrasound imaging and interpretation can be used throughout almost all of the organ systems. Ultrasound is an invaluable diagnostic modality that also provides sample collection and confirmation that would not be possible without anesthesia and surgery. Dr. Henderson has confirmed 2 cases of pancreatic adenocarcinoma in our practice, by aspiration cytology. These results would not have been otherwise possible short of exploratory surgery.
Marty's very advanced expertise and technology are also great stress reducers. SonoVet has freed me from worry about developing the skill and purchasing and maintaining expensive ultrasound equipment. There's just no way we could provide this high level of in clinic service without neglecting other valuable practice areas. Dr. Henderson's prompt and dependable service has elevated our level of practice and the results often lead to quality procedures and treatment plans that would not have been otherwise possible. Results of the quality that Dr. Henderson provide give our doctors and clients confidence to proceed and feel good about management decisions. This strengthens our bond and benefits the patient and practice. SonoVet and Dr. Henderson have truly brought a level of care into our practice that we could not provide without outside referral, and has truly provided one of the most significant improvements in patient and client care that our practice has ever been able to offer.
My Highest Recommendation goes to Dr. Henderson and SonoVet"

"We have used Dr. Henderson for our ultrasound service over 2 years now. The thoroughness and detail of his ultrasound diagnosis continue to amaze me. It seems like I learn something every time he comes to the clinic. We should get CE credit for each ultrasound he performs. My clients really appreciate the convenience of having the ultrasound performed at my clinic instead of having to go to another practice."
Todd Henry, DVM
Cypress Creek Animal Hospital
Wimberley, TX
"We at Kerrville Veterinary Clinic have been impressed with Dr. Henderson's knowledge in ultrasound and he has also been very helpful with his knowledge of internal medicine as an adjunct to his ultrasound findings. We will continue to use him and highly recommend him."
David L. Cardwell, DVM
Kerrville Veterinary Clinic
Kerrville, TX
"Dr. Henderson and his staff are always polite and try very hard to work our cases in as quickly as possible. The information gained by the ultrasounds and echocardiograms is invaluable in diagnosing and treating complex cases. The convenience of him coming directly to the patient is very convenient for both our hospital and the clients. He has been very helpful with a variety of endocrine, cardiac, and oncology cases in our hospital. I wouldn't hesitate to recommend his services to colleagues in need of a skilled ultrasonographer."
Michelle Shaw, DVM
Herbst Veterinary Hospital
Boerne, TX
"We and our clients love the convenience of having reliable ultrasonography in our own hospital. Sometimes when I refer cases out, I feel like I am left out of the loop, but by having Dr. Henderson come to us, I can keep control of more of my cases, which is more rewarding for me and ultimately more profitable for my practice."
Liz Templeman, DVM
Garden Ridge Animal Hospital
Garden Ridge, TX
"Marty provides my practice with a great diagnostic service performed in my hospital, which is convenient for my clients. It is a bonus to be able to collaborate over cases real time with great supportive literature references on disease processes."
Chris Kohnen, DVM
Bulverde Creek Animal Hospital

"SonoVet and the ultrasound imaging that Dr. Henderson provides is a great extension of our practice. With SonoVet we are able to offer our patients an in house diagnostic procedure that is quick, local and offers instant feedback and value to our clients. It is a service we cannot imagine being without."
Dr.s Kent Fischer, Michael Aven, Samantha Almany
Fischer Veterinary Clinic
New Braunfels, TX
"I place great value on being able to have Dr. Henderson consult on cases by coming to our facility to perform diagnostic ultrasound. His exams are thorough and very informative, and in many cases have changed my treatment plan based on his findings; information I would not be aware of without his input. As well, he and his technical staff are very professional and helpful. His friendly demeanor makes it a pleasure to have him consult at our facility."
Joe Burke, DVM
Cornerstone Animal Hospital
Buda, TX
"Banfield doctors in Central Texas are very fortunate to have Dr. Henderson and SonoVet. It has been a blessing for us and for our clients to have such a reliable and fast resource. While in practice in this area for the last 2 years, I found that SonoVet has always been organized and professional. And there’s nothing like having those extra medical tidbits and suggestions - not only when he comes to work with a patient, but through regular email contact too."
Andrea Sanchez, DVM
Medical Director for Banfield Pet Hospital
San Antonio, TX
"Dr. Henderson has provided a convenient, timely service to our clients, who would otherwise not be able to pursue an ultrasound for their pets."
Mark LaBrie, DVM
Alamo Dog & Cat Hospital
San Antonio, TX
"Dr. Marty Henderson and SonoVet have been doing our Ultrasounds for several years and I can tell you we are exceptionally pleased. The staff at SonoVet is especially professional, knowledgeable, skilled, prompt and go out of their way to serve our needs. Their knowledge goes beyond imaging and interpretation as they often help us with treatment recommendations. "
Michael Dunavant, DVM
Medical Director - Banfield at Brodie Lane
South Austin, TX
"Dr. Henderson is a truly gifted ultrasonographer. Marty displays a wonderful sense of compassion and caring for the cases I ask him to assess for me. This is not always the case when referring patients to a specialist. His personalized service and the smiling assistant he brings with him have added greatly to the thoroughness of my medical workups. I have found his concise and detailed written reports easy for me, and my clients, to follow. On many complex medical cases, Dr. Henderson has attached to his reports references that outline current medical knowledge concerning rare or unusual cases and suggestions for treatments. I cannot tell you how valuable this one aspect of his practice has been to me. Dr. Henderson’s service will add greatly to your practice. Ask him to become part of your medical team."
Jeff Lord, DVM

"SonoVet has been a valuable addition to my practice. Clients can now stay in town for ultrasound services and we are now able to give accurate diagnoses of cases that in the past we might never have determined the cause of disease (such as kidney tumors, gall bladder mucocele, and aneurysms). I recommend SonoVet and Dr. Henderson."
Elizabeth Long, DVM
County Line Veterinary Clinic
New Braunfels, TX
"Dr. Henderson is a valuable asset to my practice. The information I gain from Marty always allows me to make solid clinical decisions. The close relationship with Texas A&M vet school is great. Sending aspirate cytologyies to Dr. Barton and cardiac studies to Dr. Saunders has immensely improved my ability to diagnose and treat complicated diseases with expert consultations that have a turn -around time of less than 12 hours in most cases. Thanks Marty!"
Ben Kyzar, DVM
Community Pet Health Center

"I feel that having Dr. Henderson available to my practice has increased the quality of medicine that we practice. Our clients have been very satisfied with the results."
Sheridan Sloan, DVM

"Dr. Marty Henderson has been coming to St. Francis of Assisi Veterinary Medical Center for over 2 years (since 2008) to perform ultrasound diagnostics and consultation. During this time, Dr. Henderson has provided exceptional service enabling the doctors at St. Francis of Assisi to expedite the proper treatment for the benefit of our patients. The doctors at St. Francis of Assisi also appreciate the consultation service provided with each ultrasound, which allows us to give our clients immediate information on their pet's medical condition."

"It quickly became apparent that Marty was not only skilled in ultrasound in medicine, but he possessed the rare quality of integrity & character. The passion which he approaches every case with was refreshing...Marty learned to serve other veterinarian's needs and helped them elevate the level of service they provided to their clients."
- Shawn Kari, DVM - Owner of VetImage, Inc. (previous employer), Victorville, CA VetImage.us 
"I have worked with many specialists ‐ Board Certified Radiologists, Board Certified
Internal Medicine Specialists, and human sonographers. Dr. Henderson's
sonographic skills are consistently excellent. His assistance in case
management proved invaluable to me as a Board Certified Feline Specialist."
- Rachel Addleman, DVM, Diplomate ABVP-Feline - Houston, TX 
"Relying on the skills of others, I had access to 4 individuals who could accommodate our case load. In honest truth, I trusted Dr. Henderson exclusively over the others, 2 of who were board-certified radiologists. I have been able to observe his extraordinary sonographic skills demonstrated by the ability to detect extremely subtle differences in echotexture that ended up representing disease. I am confident that these subtleties would not have been detected by others, and certainly not by myself or those who practice ultrasonography less frequently. "
- Andrea Shaw, PhD, DVM - VCA Santa Anita Animal Hospital, Monrovia, CA 
"I have had the professional and personal pleasure of working with Dr. Marty Henderson since early in 2003. Dr. Henderson is highly advanced in his understanding and application of ultrasound for a wide variety of needs including cardiac, ocular, and abdominal cases. He has excellent communication skills with both clients and the veterinarians he shares cases with, and has marked patience when explaining his ultrasonic findings and when working with veterinarians under stress of large caseloads. His confidence and competence with the varied applications of ultrasonography have been demonstrated from day to day at our very busy small companion animal practice in Palm Springs, California where his caseload may exceed six or seven patients in one morning. Considering that Dr. Henderson occasionally has to visit several local clinics in one day, this is a testament to his dedication and abilities. Dr. Henderson's work is accurate and efficient, but more important, is consistent in its quality and reliability."
- Shawn Behrenfeld, DVM - VCA Desert Animal Hospital, Palm Springs, CA 
"After purchasing our own ultrasound machine and getting basic training in its use, I rapidly realized that the experience of ultrasound professionals is invaluable. After several years of use, we found that the diagnostic accuracy is far superior when the operator is on-site and present to examine and interpret their findings...Now I can't go a week without imaging patients (and often doing two or three a day) and our clients love the rapid turn around time we get from Dr. Henderson."
- Richard Palmquist, DVM - Research Chair AHVMA, VIN Consultant (Alternative Medicine), Chief of Integrative Health Services, Centinela Animal Hospital, Inglewood, CA 
"As a former practicing veterinarian, Marti has the ability to see the big picture with a case. He also is willing to offer suggestions without seeming pushy or . trying to direct further treatment decisions."
- Eric Weigand, DVM - Former California Veterinary Medical Association President, Claremont Veterinary Hospital, Claremont, CA 
"Our clinic has utilized Dr. Marty Henderson's services for several years now. After watching him perform his first few ultrasounds, we were so impressed that he has become our ultrasonographer of choice. He is very thorough and efficient, and his experience allows him to identify many lesions and diseases. Our practice treats dogs, cats and exotics. I am the only exotics vet, and 85-90% of my patients are rabbits. Due to Dr. Henderson's exceptional skills, I asked him to ultrasound my rabbit patients. Watching Dr. Henderson perform cardiac ultrasounds on rabbits, some as small as 2 pounds, has been extremely educational. I am amazed at the amount of detail and information he is able to obtain, especially compared to other ultrasonographers I've utilized in the past. He is always open to questions, and gives valuable treatment advice. Over the past few years, we have examined many rabbit hearts together, and have developed a deep understanding of rabbit heart disease, an illness that is not yet well described in the literature. In one difficult rabbit case, he was able to identify changes in the thorax consistent with pneumonia, and evaluated the heart as normal. The diagnosis of pneumonia allowed us to properly treat this rabbit and save her life. Dr. Marty Henderson is very special. He is kind and caring, skilled and knowledgeable, and one of the best ultrasonographers and veterinarians I've had the pleasure of working with."
- Sari Kanfer, DVM - Dr. Domotor's Animal House, Monrovia, CA 
"He and his ultrasound expertise have been an incredible asset to our practice, and I highly recommend him and his services to any veterinary practice. I have been trained in ultrasound and have used it in my career in Northern California. As with any procedure, I found that the more ultrasounds you performed (preferably on a daily basis), the better you become. Thus, the most proficient ultrasonographers are those who have been trained well and perform ultrasounds daily, like Dr. Henderson. After moving to Southern California, the new practice in which I was working did not have an ultrasound machine. We relied on VetImage (for whom Dr. Henderson worked) for these services. The quality of his diagnoses and his guidance have been exceptional. (This pertains to the IBD diagnosis he provided on my own personal cat, who is doing great, thanks to him!)"
-Srinivas Lingareddy, VMD - VCA Rancho Mirage Animal Hospital, Rancho Mirage, CA 
"Dr. Henderson does a thorough, professional and accurate ultrasound exam with a professional follow-up of a faxed description of the examination, with probable rule-outs and treatment suggestions. The value of this type of service is substantial in that the clients have the service performed at the clinic where their pets are treated, they have follow-up with their own veterinarian, and a diagnosis is often achieved by a non-invasive procedure."
- Amy B. Worell, DVM, Dip. ABVP-Avian - All Pets Medical Center, West Hills, CA 
"It has been my privilege to have known Marty Henderson for the past 5 years. Marty’s services afford me to keep my clients at my hospital and not have to “turf” them off to a referral hospital. His ultrasonagraphy skills are very accurate and quick. He is very easy to work with and has on numerous times gone out of his way to accommodate me and my patients. Marty’s services have been invaluable to my practice."
- Ford Suehiro, MS, DVM - Beverly Hills Small Animal Hospital, Beverly Hills, CA 
"Dr. Henderson not only does an excellent and proficient assessment of the cavity requested, he also helps by making recommendations for case management. Dr. Henderson's personal integrity & reliability are beyond reproach. We highly recommend his services as an ultrasonographer and fellow veterinarian."
- Margaret Horstmeyer, DVM, Dip. ABVP-Feline | Barbara Allard, DVM |Patty de Wet, DVM | Lin S. Vaccarello, DVM - Northside Veterinary Clinic, San Bernardino, CA 
"We have worked with Dr. Henderson over the past five years, and even though we understand his motivations for leaving our area, we are reluctant to see him go. He has proven to be a large asset to our hospital, both in diagnostics and personal relationships. Many days he has altered his schedule to accommodate our needs for emergency cases and has allowed us to add on cases when necessary. He has always been willing to discuss the details of each case and pursue obtaining ultrasonic information to assist us with the diagnosis. He is a valued colleague, and we would highly recommend his services."
- Richard T. Johnson, DVM - Medical Director, VCA Central Animal Hospital, Upland, CA 
"The diagnostic information provided by Dr. Henderson has been invaluable and never in question during the time I have known him. In addition, he provides valuable case treatment recommendations in conjunction with his services, at no extra charge. We are in an area where clients demand high quality service and accuracy in evaluations, and Marty has contributed greatly to that."
- Tiffany Margolin, DVM, Dip. ABVP-Avian VOM Cert. - Animal Bird Wellness Center, Westlake Village, CA 
"I have received extensive one-on-one training from [Dr. Henderson] using the LOGIQe ultrasound machine on a variety of species (dogs, cats, ferrets and rabbits) in both cardiac and abdominal studies in addition to ophthalmic scans. Dr. Henderson's expert knowledge and years of experience has helped me tremendously in developing and refining my skills in ultrasound and related medicine."
- Ramona Forelle, DVM - VetImage, Inc, Santa Monica, CA 
"Dr. Marty Henderson has been performing our ultrasounds for over 5 years and has never disappointed me. He has an excellent knowledge base in medicine and relates this with his ultrasound findings. On a number of occasions when we sent patients to a specialist based on Dr. Henderson’s recommendations, none of his work was ever disputed. Dr. Henderson is a dedicated and caring veterinarian who has a high standard of practicing medicine."
- Eugene Cannarella, DVM - Animal Care Hospital (retired), Apple Valley, CA 
"Dr. Henderson has always been patient with my requests for explanation of the images he generates, and I have always appreciated the insight our discussion of cases has helped me gain."
- Robert Reed, DVM - Valley Animal Medical Center, Indio, CA 
"The caseload he experienced here in Southern California allowed him to see a large number and variety of cases in a relatively short amount of time, thereby increasing his expertise in all areas of ultrasonograpghy. This can make him invaluable for second opinions, even in offices that currently utilize ultrasound. Dr. Henderson's demeanor and professionalism are beyond reproach. He strives
to bring added insight to cases, above and beyond the ultrasound findings"
- Michael Weigand | Walter Cailleteau, DVM - Terra Vista Animal Hospital, Rancho Cucamonga, CA
"Dr. Henderson is a completely reliable and knowledgeable doctor. He is careful in his work, checking all possibilities. I have always been able to rely on his ultrasound abilities. His recommendations regarding each case have been helpful. He is extremely kind and gentle with all of my patients. We have always been pleased to welcome him into the clinic."
- Nancy Modglin, DVM - Holistic Options Veterinary Care, Redlands, CA 
"I have used the Ultrasound services of Dr. Marty Henderson since 2003, and am very pleased with his competency, professionalism, knowledge and communication skills. The quality of our practice has risen with Dr. Henderson's services. Dr. Henderson is a man of integrity. He provides recommendations that are
of great help in the management of our cases. Even in our terminal cases, the
validation of an ultrasound is very helpful to our clients."
- Leonard Sigdestad, DVM - Loma Linda Animal Hospital, Loma Linda, CA 
"Dr Henderson is a dedicated and very conscientious ultrasonologist. In addition to his ultrasound proficiency, Dr Henderson is a good diagnostician and will often offer valuable diagnostic and therapeutic advice. His exams and written reports are always thorough and professional. I personally find our discussions during and/or after the ultrasound study to be the most helpful. Dr Henderson has a very collegial attitude and is more than happy to demonstrate his findings during the exam, if a doctor chooses to be present, although he is more than capable of doing several ultrasound exams with only technician support (on those wild and crazy days). Since veterinary caseloads can be unpredictable, it has always provided peace of mind that Dr Henderson usually can fit us into his schedule within a day or two of our call. On a more personal note, Dr Henderson has always behaved very professionally and has demonstrated numerous times his dedication to our profession through the very current, cutting edge knowledge that he brings to the hospital. He has always treated my staff and our patients with care and consideration."
- Sylvia V. Domotor, DVM - Dr. Domotor's Animal House, Monrovia, CA 
"My practice employs 2 full time and 1 part time veterinarian. We are an extremely fast growing hospital located approx 30 min. from Palm Springs and approximately 2-3 hours from any specialty referral practices. Although we own our own ultrasound machine, we consistently utilize Vetimage to handle our more complicated cases. We have the choice of sending clients to a referral hospital, or keep cases in house. In situations where our clients wish to utilize in house services, we have been very pleased with the quality of ultrasound services we have received from Marty and VetImage. I am fortunate to have clients that have the financial ability to seek advanced diagnostics. We have had
many clients go on to have further procedures at specialty hospitals and this has allowed us the ability to
confirm the quality of the ultrasound evaluations we received from Marty."
- Kathryn Carlson, DVM - Village Park Animal Hospital, La Quinta, CA  
"Ultrasound is an important diagnostic tool and having it available in our small practice has enabled us to achieve a high standard of patient care plus has kept important diagnostic revenue "at home" rather than referred elsewhere. Our reputation relies on the skill, punctuality, and integrity of the service we choose for this important service. Dr. Henderson provided for our needs with excellent and meticulous work over the many years he served our area. His professionalism was consummate and his service dependable. I would not hesitate to employ his services at any time were he still located in our vicinity and it is with utmost regard that I recommend his ultrasound services. I am certain you will be pleased as well."
- Wendy Brooks , DVM - Mar Vista Animal Medical Center, Los Angeles, CA  
"His calm, level-headed, ever-prepared persona was much appreciated. His ultrasound skills and clinical interpretations were most helpful to both our clients and our clinicians. He saved several animals and their owners from ex-laps with his in depth interpretations on abdominal ultrasound exams. Whereas my ultrasound skills might be adequate, Dr. Henderson was always my go to man when there was any doubt, and, as most of you know, doubt can certainly creep in whenover- or under-interpreting an ultrasound study."
- Kevin Fenton, DVM - All Creatures Veterinary Clinic, La Quinta, CA 
"His expertise in diagnostics and ultrasound is second to none. Whenever we had an ultrasound procedure scheduled we always looked forward to having Dr. Marty perform the procedure. His kindness, expertise and professionalism is second to none. He has been a great asset to our practice and I don't know how we could have gotten along without him."
- Lazlo Frics, DVM - West Main Animal Hospital, Alhambra, CA  
"We are a very busy 9 doctor, emergency hospital. It has been my honor and pleasure to know Dr. Martin Henderson over the past 5 years and I have the utmost trust in him and respect the work he does. Dr. Henderson will be an asset to any practice."
- Mary Nightingale - Hospital Manager, VCA Central Animal Hospital, Upland, CA   |
