Where Pets are Family!

Dr. Guy Osmun, along with his wife Julie, opened Companion Animal Hospital in a small building on the west side of Linden in 1990. There he worked as a solo practitioner for 8 years before building his current hospital on Bridge Street in 1999, along with a building addition in 2001. Dr. Osmun has continually strived to improve his practice. Companion Animal Hospital presently has 5 doctors leading a 30+ member team to serve the pets and clients in our community. Experienced and skilled veterinarians and staff, state of the art medicine, a beautiful, spacious facility – all combine with a special love and dedication to your pet’s well being, help make Companion Animal Hospital your BEST choice for a Veterinary Hospital!
