I became a physician to make a lasting impact on people's health. When I studied as a Buddhist monk, I knew that the best way to do this was to develop a strong and trusting relationship with people. I am a dual board-certified physician in both Family Medicine and Sports Medicine. My goal is to provide compassionate, comprehensive care to all patients to recover from any injury or illness. This involves sharing the latest up-to-date information to guide patients in the best way possible. I provide primary care for patients of all ages, including preventive care and treatment for all injuries and diseases. I enjoy staying active by running and playing golf and basketball. I also enjoy spending time with my family and traveling the world.

I love Dr. Hsu, he listened to everything I had to say, even though I had a long list. He addressed all my concerns very thoroughly. I received all the test that I needed, and he explained everything in detail to me. He also explained why I was doing the test and prescribed medication. He let me know when to take it and the side effects and what are the benefits of it? He also gave me options on what I wanted to do. I felt that he did a great job in informing me and he seemed to care about me and made me feel at ease and happy with my decisions I would most definitely recommend Dr. Hsu for anyone who needs a doctor.
