Our Doctors

Dr. Alan Gassel, </br> DVM & Founder  photo

Dr. Alan Gassel,
DVM & Founder

Dr. Alan Gassel has been practicing veterinary medicine in Knoxville since 1977. He founded Concord Veterinary Hospital in the spring of 1979, in a trailer behind its current physical location. Currently, Dr. Gassel supports the hospital as an administrator. To Dr. Gassel, the greatest joys of working in the veterinary field are building the relationships between both veterinarians and clients, and facilitating the relationships between pets and their families. Dr. Gassel is from the Chicago area and, in addition to being a veterinarian, has run 22 Chicago marathons. At home, his family includes his wife (a fellow veterinarian), daughter, six rescued dogs, and one rescued cat. Dr. Gassel’s wife, a fellow animal-lover, operates a horse training and boarding facility, and their daughter is a national horse-jumping competitor.

Dr. Currier’s favorite part of being a veterinarian is seeing the love clients have for their pets, and playing a role in their welfare. She has always had a deep love for animals, and a passion to help them and educate their owners. In addition to being a dedicated veterinarian, Dr. Currer enjoys whipping up sweet treats at home in the kitchen, spending time with her husband and two sons, and playing with her golden retriever, Boone.

In addition to being a veterinarian, Dr. McCormick enjoys spending time with his girlfriend’s Pembroke Welsh Corgi, Oliver, and his Labrador Retriever, Baxter. When it comes to tricks, one of Baxter’s most impressive feats is tricking people into feeding him breakfast twice.
