Care philosophy
My job as a general internist isn’t just to provide sound medical advice — it’s to make sure patients understand their conditions so they can make informed decisions for themselves. I also guide patients and their families through the healthcare system, which can be overwhelming. Trust and mutual respect are the foundation of a long-term doctor-patient relationship, and I strive to create that with every person I care for.
