Dr. Jean Quaintance, Owner and DVM

Dr. Quaintance was raised in North Salem, NY, where she rode horses competitively and worked at the local foxhound kennel. She graduated from the Wooster School in Danbury, holds a B.A. from Colorado State University and received her DVM from the University of Wisconsin School of Veterinary Medicine. Dr. Quaintance has been a veterinary technician since 1994 and a veterinarian since 2006. Her interests include surgery, dermatology and of course, bulldog medicine. She enjoys spinning, running, and chasing her toddler all over town and has a coffee obsession.

Dr. Theresa Kaeser, Owner and DVM

Dr. Theresa Kaeser grew up in Seymour, Connecticut. She attended University of Connecticut receiving a Bachelor’s in Animal Science and received her D.V.M. in Prince Edward Island, Canada at the Atlantic Veterinary College. During breaks from school, she was a dog groomer and veterinary technician. She started practicing as an associate immediately after graduating in 2012, and after 3 years decided to venture into relief medicine of which she currently does now. She loves to spend time with her fiancé Jay as well as their fur kids, Canon, Marcus, Syd, Tillikum AND a Flemish Giant rabbit named Anna. Theresa has a special interest in small animal dermatology and quality of life care. She is also fond of small mammals (especially rabbits) and wildlife medicine. She mainly focuses on client education and making the best most practical decisions for her patients. When she is not practicing, she teaches parasitology to future licensed veterinary technicians at a community college. In her spare time you’ll find her traveling around the world, running in the woods, watching Disney movies, enjoying Mother Nature and happens to have a huge obsession with owls.

Donald Quaintance, Practice Manager and Technician

He holds a B.S. from Colorado State University, where he met his wife, Dr. Jean Quaintance, and received his M.S. in Traditional Chinese Medicine from Meiji College in Berkeley, CA. He has been a veterinary technician since 1995, and enjoys the opportunity to apply his Chinese Medical knowledge to the “four-leggers” where needed to facilitate a holistic treatment approach. His interests include obstacle course racing, college football and impromptu dance parties with his daughter, Keala.

Lindsey T. D'Addio, Office Manager and Reception

Lindsey was raised in Somers, NY. She attended Pace University in Pleasantville, NY while working full time in private aviation. When she and her husband Matt moved to New Fairfield, CT in 2008 she decided that it was time for her to finally fulfill her dream of working with animals. She worked for a wonderful animal hospital in Danbury for almost 9 years where she made lots of lasting friendships, but due to a change in her son Dylan's schedule (Kindergarten!), she had to make some changes of her own.

She is very excited for this new venture with an amazing team of people who happen to be equally amazing friends! She has a love for going on exciting new adventures with her son (especially out and about in nature), playing board games, and anything related to goats and cows. She has an incredible and enthusiastic passion of learning all things new and unique.
