MEET OUR STAFF

Dr. Tillema

Dr. Tillema grew up on a dairy in a small town in West Texas. Dr. Tillema served in the United States Navy and then when his tour ended, he began his studies to become a veterinarian where he worked three jobs and went to school. Dr. Tillema began practicing veterinarian medicine in upstate N.Y. where his patients were big and small. He soon moved to California where he opened his own mixed practice as a mobile unit. Seeing that he was limited on what he could do for his small animal clients, Dr. Tillema opened a small animal practice in Corona. Dr. Tillema was injured by a bull and acupuncture was the only pain of relief that he had, after that incident Dr. Tillema studied acupuncture at the Chi Institute where he found that Western and Eastern medicine worked better together than any one alone. Dr.Tillema also has an interest in orthopedic medicine as well as general practice. When the Doctor isn’t working he enjoys skydiving, zip-lining, hiking, fishing, barbeques and watching and playing sports.
