Our Staff

The most experienced veterinary surgeons, diagnosticians, and highly-educated and caring staff.

Dr. Grant Myhre

After growing up on his family's Midwest farm, Dr. Myhre has continued to build on his knowledge of horses. Graduating from the Minnesota College of Veterinary Medicine and completing his Large Animal/Surgery internship at Colorado College of Veterinary Medicine, and a two-year residency at Cornell University, he launched his career as a surgeon (and later, hospital director), leading the Rochester/Myhre Equine Clinic to the forefront of veterinary medicine.

Dr. Myhre has held a directorship in several professional organizations, including the New Hampshire Horse Council, New Hampshire Thoroughbred Breeders and Racing Association, New England Equine Research Fund, the New England Equine Care and Hospital Development Fund, the New Hampshire Farm Museum, and the New Hampshire Academy for Equine Sciences Charter School. His interest in human medicine (6 week rotation) and association in nuclear scintigraphy (authorized user and radiation safety officer) spurred his interest in cutting-edge diagnostic technology. He was the pivotal individual in bringing the only nuclear medicine lab to Rochester Equine Clinic (now Myhre Equine Clinic) in Northern New England. This laboratory has now grown to include radiopharmaceutical cancer treatments and one of the most modern gamma cameras and computer systems in veterinary medicine, complementing this modality. Dr. Myhre was also the first in Northern New England to pioneer innovations from arthroscopy to digital radiology.

Dr. Myhre has also presented at over 100 meetings and conferences. The latest at the prestigious AAEP in San Antonio, “The Standing Colic Surgery on the Draft Horse,” which was motivated by his extensive experience with drafts and the successful surgical correction of a large colon torsion in a 2,800 pound Belgian Draft horse in 2006. Dr. Myhre has presented at the AAEP previously (1998) on Scintigraphy in Private Practice to approximately 3,000 members. Dr. Myhre still presents to various groups including his annual veterinary/technician and farrier meetings, and to the Equine Charter students as well as various New England groups. He has been a favorite featured speaker at the nationally acclaimed “Equine Affaire”.

Dr. Myhre's professional interests lie in improving our already extensive diagnostic imaging modalities. Along with nuclear medicine, digital radiography, and Doppler ultrasound, he has added computed axial tomography (CAT Scan) to Myhre Equine Clinic. His vast surgical ability and experience (31 years) leads all in the Northeast. Although he is comfortable with most surgery from arthroscopy to colics, he enjoys the challenge of the “cutting edge” such as laser surgery and laparoscopy.

Dr. Myhre is an avid adventurer with interests in aviation, riding, sailing, and diving. He helped establish the first equine charter school in the United States because of his interests in education. As Einstein said, “Learn from yesterday, live for today, and hope for tomorrow. The important thing is to not stop questioning.” Dr. Myhre lives his life by this philosophy:
“With this principle we not only make ourselves better but we better mankind.”

Dr. Ron Vin, DVM, Dip ACVIM (LAIM)

Dr. Vin graduated from the Koret School of Veterinary Medicine, the Hebrew University of Jerusalem, Israel in 1996. He trained in large animal medicine between 1997 & 2002, working with the Rochester/Myhre Equine Clinic (as an intern and a staff veterinarian) and at Tufts University Cummings School of Veterinary Medicine (as a research fellow and a resident in large animal medicine). Dr. Vin is a Diplomat of the American College of Veterinary Internal Medicine (ACVIM). Following his residency at Tufts University, Dr. Vin founded 'Equine Diagnostics', a mobile unit providing referral diagnostic services to equine practitioners throughout New England. In 2005 Dr. Vin joined the Center for Veterinary Care, Millbrook, NY, and became the director of their equine division. In 2008 Dr. Vin returned to northern New England and joined Dr. Myhre at the Myhre Equine Clinic. Dr. Vin shares his time between caring for internal medicine patients at the clinic and providing ambulatory specialized diagnostic and sports medicine services. Dr. Vin's main clinical interests are emergency and critical care, neurologic, gastrointestinal, respiratory diseases and diagnostic ultrasound. Internationally featured, Dr. Vin has presented at the AVMA Convention, Equine Affaire and to the Israeli Association of Equine Practitioners. He has authored/coauthored articles that have been published in several scientific journals. During his free time, Dr. Vin enjoys spending time with his family, reading, running and horseback riding.

He then went on to obtain a Doctor of Veterinary Medicine from Cornell University’s College of Veterinary Medicine, where he spent most of his free time in the large animal hospital. Following graduate school, Dr. Myhre completed a one-year Internship at Peterson and Smith Equine Hospital in Ocala, Florida followed by a 3-year surgical residency at Palm Beach Equine Clinic in Wellington, Florida. Having survived the heat, he has returned to New England to begin practice with his father, Dr. Grant Myhre.

He lives with his intelligent and talented fiancee, Dr. Lauren Wilmarth, who is a veterinarian and just completed a 3 year residency in small animal neurology. He also lives with his cat, Mittens. Dr. Myhre will continue the Myhre Equine Clinic’s tradition of excellent medical and surgical care.

Dr. Alyssa E. Keto, DVM

Kimberly Simmons

Receptionist

Kim's love of animals began young, with every stray dog and cat in the neighborhood ending up at her house (much to her parents’ dismay!). She rode her first horse while still in diapers, took lessons through 4-H, and rode friend's horses as often as possible growing up. Kim attended Thompson School of Applied Science, where she took classes in Animal Science. She worked as a small animal Veterinary Technician in the early nineties before deciding to be a stay-at-home mom. Kim bought her first horse, Jester, a 5-month-old grade weanling, in September of 2001, and adopted her two Morgan mares in 2009. Her 4th horse, a sassy rescue pony, was adopted after having life-saving surgery here at Myhre Equine. In 2011 Kim returned to the work force at Myhre Equine Clinic as a Veterinary Receptionist and a small animal Technician at our sister hospital. In 2015 Kim transitioned to working exclusively at Myhre Equine Clinic.

When not at work, Kim can be found working around her farm, taking care of her horses, dogs, cats, and chickens. She might also be photographing nature and the wild critters that wander through the farm, kayaking, hiking, riding, reading, or writing.

Takoda can be found sleeping under the desk when Kim is working. Should you be worthy, he will interrupt his nap to say hi! Takoda enjoys long walks, playing ball, meeting new friends, and tunneling in the snow. He also likes to bask outside in blizzards and during sub-zero temperatures, ignoring Kim's calls to come inside.
