Dr. Tillema's Bio

Dr. Tillema grew up on a dairy in Texas where hard work wasn’t an option, it was a necessity 24/7. Dr. Tillema always believed if you take care of the animals, they will take care of you. As you might guess, lots of dogs and cats were dropped off on the dairy and Dr. Tillema was always providing care for those animals that were in need as his dad always joked, “You should open a veterinary clinic.” After graduating from High School, Dr. Tillema had many athletic scholarship opportunities but chose to serve his country in the U.S. Navy. After four years of working with an outstanding search and rescue team, Dr. Tillema got out of the military to work on his passion for veterinary medicine. Dr. Tillema graduated from veterinary school and after a few years working in upstate New York, he opened his own mobile practice in Southern California. He soon after, opened up his brick and mortar practice in beautiful Corona, Ca. In his spare time, he enjoys endurance events, skydiving, training, hiking, and playing and watching sports. Dr. Tillema also enjoys working with the FFA (Future Farmers of America) and the military. He has 5 hairy kids that he enjoys spending time with; Littles, Rebound, Lola, Cujo, and Stevie.
