Founding veterinarians Joseph and Mariel Edhlund at Gentle Vets work hard to make Gentle Vets Advanced Care the most advanced state of the art veterinary hospital in Hawaii. We have equipped the hospital with the best and latest equipment and strive to provide the best expertise in the world, let alone Hawaii. Our Seimens 64 slice CT scanner is rivaled, but not surpassed, in only 4 of the 28 US veterinary schools in the US. Our equipment list of CT scanner, digital radiology, fluoroscopy, surgery suite with laminar flow HEPA filtered air supply, Leica Wild 690 operating microscope, extensive orthopedic and soft tissue surgery instrumentation, ultrasound, endoscopy and arthroscopy equipment is unequaled in Hawaii. In search of excellence we have partnered with Southern California Veterinary Specialists and now offer advanced surgery including total hip replacement as well as advanced heart surgery and other soft tissue and cancer surgery at Advanced Care by Board Certified veterinarians as primary surgeons or consultants to our primary surgeons. In addition we have developed a close working relationship withe the team of SCVSH.

Dr. Walker graduated from Texas A&M University summa cum laude in 1974. He completed his neurology residency at Auburn University and then his surgery residency at the University of Tennessee where he remained as Associate Professor of Surgery until 1987. An esteemed educator, Dr. Walker has lectured at numerous American and European Universities, national and international meetings including a formal address to the World Congress of Veterinary Medicine and Surgery. As a Diplomate of the American College of Veterinary Surgeons, Dr. Walker served as Head of the College’s Examination Committee, and was Chairman and educator at the Forum for the Orthopedic and Neurology sections of the College of Surgeons for ten years. Cambridge University in Cambridge, England welcomed Dr. Walker for a teaching sabbatical from 1987-1988. His contributions to education have garnered teaching awards to every level. With numerous contributions to journals, papers, proceedings as well as chapters in textbooks on veterinary orthopedics and neurology.

Armed with keen sensibilities for veterinary diagnostic and surgical advancement, Dr. Walker worked with Dr. Barclay Slocum in the development of the TPLO procedure for cruciate repair and continues as one of the foremost surgeons to progressively incorporate minimal invasive surgical techniques, stem cell technologies and laser technologies.

Dr. Warren Sakamoto has joined our practice as well. Dr. Sakamoto is Board certified in Small Animal Veterinary Practice – something only two doctors on Hawaii have achieved. His well rounded skills with four decades of experience will ensure that our patients always receive the best possible care. Everyone who has met Dr. Sakamoto will understand the intensity of his care for animals.

Although the Hawaii government only requires 15 hours of continuing education per year the veterinarians at Gentle Vets typically obtain hundreds of hours of continuing veterinary medical education annually. This is obtained by both in-house seminars where veterinary experts are brought in, and by attending specialized veterinary seminars in the US and around the world. Veterinary dental and ultrasound specialists Dr. Jean Hawkins and Dr. Paul Brazell were brought in from the US and Canada for days of intensive learning. Dr. Jon Dyce, head of surgery at The Ohio State has come to provide training in hip replacement. We have received extensive training from Board certified Surgeons, Peter Vogel while Board certified Surgeon Tom walker remains a frequent consultant surgeon. Our clients undoubtedly notice that we are infrequently off-island. Sometimes we wish it is just a vacation but almost all the time we are attending continuing education conferences to constantly upgrade our skills and abilities. Our veterinarians have attended the Western Veterinary Conference, the meeting of the Association of Emergency and Critical Care Society, the Fetch Veterinary Conference in San Diego, Veterinary Society of Surgical Onocolgists, World Veterinary Cancer Society Conference, American Veterinary Cancer Society, Hawaii (Human) Cancer Society, American Society of Veterinary Radiologists, the Biomedtrix total hip and knee replacement course at the University of Florida College of Veterinary Medicine, the Western Veterinary Conference,  numerous conferences of the European College Of Veterinary Ophthalmogists, the Australian College of Veterinary Scientists, the Hawaii VMA, American College of Veterinary Ophthalmologists Conferences, World Small Animal Veterinary Conferences, American College Of Veterinary Surgeons conferences, Australian College of Veterinary Scientists meetings as well as externing at Advanced Veterinary care in Melbourne Australia under the guidance of Dr. Sam Snelling, President of the Australian Board of Veterinary Surgeons. Dr. Joseph Edhlund has completed all course work on his Master’s degree in Public Health with a special focus on infectious diseases. Our commitment to Advanced learning to provide optimal care for you pet is obvious


Gentle Vets also enhances the educational development by mentoring pre-veterinary students enrolled at the University of Hawaii through both volunteer and paid positions at the hospital.

A few of the highlights of our specialized veterinary procedures:

  • TPLO Cruciate ligament repair
  • Total Hip Replacements
  • Tracheal stent placement for dogs with collapsing tracheas
  • Pericardectomy (removal of the sac around the heart) for correction of cardiac tamponade
  • Gastric Dilatation-Volvulus (Bloat) correction in many patients
  • Cancer therapy in many patients
  • Halter Monitoring for detection of cardiac dysrhythmias

We love answers! To that end, Gentle Vets has continually expanded our equipment and abilities. We are delighted to have acquired a Seimens Somatom Sensation 64 slice CT scanner. This machine is so advanced that few veterinary colleges have one. This machine allows unrivaled visualization of the entire body from the nose to the pelvis. The 3-D reconstructions are absolutely amazing in letting us look inside your pet. CT is considered the Gold Standard of diagnostic tools in human medicine and we enjoy using these advances in veterinary medicine

The image quality is striking and will bring our medical and surgical abilities to an entirely new plane. The machine is also available for use by other veterinarians in Hawaii.

In addition to our new CT scanner, Gentle Vets Advanced Care has acquired the only fluoroscope currently dedicated to veterinary use in Hawaii. This is a video X-ray machine which allows excellent visualization of problems where motility must be analyzed such as collapsing trachea or mega-esophagus which causes regurgitation, some spinal conditions where dynamic studies are essential and can enhance orthopedic surgery by intra-operative imaging allowing accurate placement of prostheses.

As we perform both ophthalmic and neurosurgery procedures, magnification is essential. Some of the sutures used in eye surgery are no thicker than a white blood cell or about 1/6 the thickness of average human hair. The sutures are literally invisible to most naked eyes. For these procedures we use our Leica Wild 690 Operating microscope. This exceptional machine allows two surgeons to work as well as additional observers through the video camera. Through the use of foot operated zoom, focus and XY control, the surgeons are free to make the most minute of surgical motions with their hands and fingers.

Gentle Vets also offers in-house endoscopy and ultrasound. Our MyLab 30 is a top of the line state of the art Ultrasound and offers an excellent sonic look inside your pet. With extensive experience this machine allows a quick look through your pet’s abdominal organs.

In addition to CT, Ultrasound, Fluoroscopy and Digital X-Ray which allow us to look from the outside in, we have several different flexible and rigid endoscopes to allow us to look from the inside, whether down the nose or trachea or into the stomach and intestine or into the abdomen or thorax. Endoscopy offers the potential to avoid surgery when your pet has swallowed something s/he should not have swallowed by allowing us to retrieve the objects. We have recently removed coins and fish hooks from stomachs with no surgical incisions.
