Bill Kellner, DVM
Dr. Bill Kellner, our Chief of Staff, is a graduate of the University of Vermont. After college he moved to Colorado where he took up dogsled racing with his five beloved Siberian Huskies. Bonding with his “team” helped to crystallize his passion for animals and led to his desire to become a veterinarian—therefore Dr. Bill moved his lead dog, Mokee, to Michigan where they attended Michigan State University’s College of Veterinary Medicine.
After graduating with honors from MSU, Mokee gave Dr. Bill the OK to get married and the two of them and Dr. Bill’s new wife moved to New Mexico. There, he practiced in a mixed-animal hospital on the northern New Mexico Highlands, and after getting kicked by wild range cows one too many times, Dr. Bill decided it was time to focus exclusively on companion animals.
In time, Dr. Bill, his not-so-new wife and Mokee moved to Vermont and opened Ark Veterinary Hospital. Dr. Bill and his wife have two kids and share their home with two dogs and a cat. Bill’s lead dog, the wonderful Mokee, lived to be nearly 18.
Sarah Smets, DVM
Dr. Sarah Smets was born and raised in Belgium. There, she first discovered her love for animals after constantly being surrounded by dogs, horses, sheep, goats and Flemish giant rabbits on her family farm. Before entering the veterinary field, Dr. Sarah received a master’s degree in History at Ghent University and a master’s degree in political science and non-profit organizations at Suffolk University. While earning her undergraduate degree, she studied abroad for a year in Sweden at Uppsala University. There she met her husband, Anders, and he was able to persuade her to move to New England where he grew up.
While working as a fundraiser for MGH and the Animal Rescue League of Boston, Dr. Sarah decided that she wanted to take her love for animals to the next level and chose to start a career as a veterinarian. After commuting across the Atlantic Ocean for several years, she graduated Magna Cum Laude from the Veterinary program at Ghent University with a focus on companion animals. During her studies she participated in many externships, including a month-long externship in the dental and oral surgery department at UC Davis.
Andrew Koenitzer, DVM
Dr. Andrew Koenitzer was born in Milwaukee, Wisconsin and raised in Cedarburg, just north of the city. He was always fond of the outdoors and spent most of his childhood summers camping and swimming. This love of the outdoors led him to attend the University of Minnesota, where he studied wildlife management. While obtaining his undergraduate degree, Dr. Andrew worked at the Raptor Center and the Wildlife Rehabilitation Center, where he realized that treating individual animals was his true passion—so his next step was working at a companion animal veterinary clinic and a dermatology specialty clinic.
Dr. Andrew returned to his home state for veterinary medical school, attending the University of Wisconsin-Madison. He continued to work with wildlife as a technician at the National Wildlife Heath Center and assisted in research projects studying dog allergy treatments. He was also active in Wisconsin’s Veterinary Medical Association as the student representative for the Public Education and Marketing Board.
