All Pets Animal Hospital was founded by Dr. Patrick Choyce in Katy, Texas, in 1990 in a small strip center on Mason Road. In 2011, Dr. Choyce opened the current state-of-the-art, award-winning facility, and this greatly expanded the number and types of services the hospital could offer to area pets. In the last few years, the hospital has experienced dramatic growth, adding three veterinary associates to the practice and providing routine health care as well as 24-hour emergency care for pets in the area.
