Meet the Owners: Drs. Walter and Holly Merker
In 2022 Drs. Walter and Holly Merker became the new owners of Orange Grove Animal Hospital and have continued the high standard of care Tucson, AZ area residents have been accustomed to. They are both graduates of the UC Davis School of Veterinary Medicine and made their way to Tucson in 2012.
