Empire Orthopedic Center was founded by Thomas Donaldson, M.D., in 2006. In expanding his practice, Dr. Donaldson’s goal was to add additional services to the practice so that his patients and the community would be able to receive complete care from our facility. In doing so, we are proud to announce the addition of Theodore K. Gregorius, M.D., who has recently joined the practice. He is a Board-Certified, sports-trained orthopedic surgeon who specializes in arthroscopic procedures in upper and lower extremities.

We have also recently opened the physical therapy department, supervised by Steve Zecher, R.P.T., who has been a member of the Loma Linda community for over 20 years. In opening this new facility, our goal is to provide you with a care plan and the convenience of orthopedic evaluation, onsite state-of-the-art diagnostic and treatment technology, as well as physical therapy services in one location.

If you are considering professional care due to an orthopedic problem, a work-related injury or you have an injury that is prohibiting you from playing the sport you love, our staff is trained and committed to providing you with the best education and recovery plan possible to get you back doing the things you love.

We are an independent, physician-owned practice which allows us to provide you personal care from beginning to end, with maximum time during your appointment to thorough follow up by our physicians and staff.
