The Animal Hospital of Oshkosh is a veterinary practice caring for small animal pets, such as dogs, cats, small mammals and exotics. It originally opened in March, 1998 under the ownership of John Merrick, D.V.M. Dr. Merrick lived and practiced in Kenosha, so Diane K. Grede, D.V.M. was hired to operate and manage this clinic. Dr. Grede purchased the practice from Dr. Merrick in August, 2001 and has held it solely since.

The practice originally opened in a 2200 sq. ft. storefront just east of the current location. The clinic maintained that location for 7 years until February 2006 when we moved next door to a new free-standing building designed specifically to meet the needs of a growing, progressive animal hospital.
