About Me

care philosophy

I listen to what the patient has to say so I can learn as much as possible about their concern before diagnosing them. I also believe in educating patients so they have the knowledge necessary to be active participants in their own health care.

biography

I believe that health care should be patient focused. I am passionate about working with each patient and the rest of the care team to determine the best treatment plan to meet their healthcare needs – and achieve the best outcomes.
