I chose a career in medicine because I enjoy understanding and helping people. I also love the fact that in medicine, scientific innovations continuously empower physicians to cure diseases that have been hard to manage in the past. I believe caring for patients as people is really at the heart of medicine, and it’s a great privilege to be able to help people in need. My practice approach is simple: listen carefully, examine thoroughly, then tailor care as much as possible to an individual’s needs.
