Tim Synar, DVM

Dr. Tim Synar grew up in Muskogee County and joined Animal Medical Center in 1976 after graduating from Oklahoma State University College of Veterinary Medicine. He became co-owner in 1977. Dr. Synar’s focus was initially on dairy medicine, as he worked with the 39 dairies in the practice’s 60 mile service area. In the 1980s, as the dairy industry declined in the Muskogee area, Dr. Synar gradually transitioned to small animal medicine. He began practicing small animal medicine almost exclusively in the early 2000s. Dr. Synar resumed the title of associate veterinarian in 2015 when the practice was sold to Dr. Walkup. He continues to focus on small animal medicine with a special interest in surgery.
