Our History

In 1967, Dr. Norman Osgood, a local veterinarian, purchased property in Oak Creek, Wisconsin: a residence, two buildings capable of housing 20 dogs each, and adjacent land. He converted his garage into a two-room clinic for his veterinary medicine practice. In 1971, Dr. Osgood broke ground and constructed a new clinic on the adjacent lot on Ryan Road. He added an associate veterinarian and receptionist to his expanded practice and founded Brentwood Animal Hospital.

Today, we are located in the same building but have a new boarding facility within the clinic itself. Newly remodeled, the facility continues to expand and add new staff members. Two of our five veterinarians are Dr. Osgood’s twin sons, Doctors Brad and Brett Osgood!

Dr. Brad and the staff at Brentwood are outstanding! The staff always makes us feel welcome even when just picking something up. They are compassionate and caring. As for Dr. Brad, not only is he a great vet, but he is a wonderful person! He not only makes sure you understand the care your pet is getting, but he takes his time with your pet to make them feel comfortable!! Our family has been going here since the 70’s and every one of our dogs has always received the best possible care. I would most definitely recommend Dr. Brad and the staff at Brentwood and I have to family & friends!
