Dean Wallace, DVM
(Founder and Owner)
Dr. Wallace was born in Wakefield, Massachusetts. His interest in biology led to a Bachelor of Science Degree from the University of Massachusetts.
He earned his Doctor of Veterinary Medicine degree from Purdue University School of Veterinary Medicine and Surgery in West Lafayette, Indiana in 1975.
He began his career in Kingston, New Hampshire working for Dr. Dan Burbank at the Kingston Animal Hospital. Dr. Wallace left Kingston with a dream of opening his own hospital. In 1976, he founded the Plaistow Animal Medical Center in Plaistow, NH. Over the next 30+ years the practice grew until, in 2006, Dr. Wallace returned to Kingston when he moved the hospital just a few miles north to its current location, changing its name to the Plaistow-Kingston Animal Medical Center.
Dr. Wallace’s professional interests include orthopedic surgery, exotic medicine and diagnostic imaging. He and several of his technicians have donated vacation time over the years working free spay/neuter clinics to help control the population of stray and orphaned animals on the islands of Anguilla, Granada, Carriacou and Gouyave.
