I believe everyone has the equal right to high-quality medical care regardless of race, ethnicity, religion, disability, sexual orientation/identity, or background. In my internal medicine role, I find satisfaction in the diverse range of cases and the collaboration with a multidisciplinary team from the point of case admission to discharge.”

“Patients come to me at a difficult, low point in their life and share information they may have never talked about with anyone. I am honored to have the opportunity to listen, validate, and partner with them to create an individualized treatment plan to help them move forward and feel better. 

“I take a trauma-informed care approach to providing care to my patients. This helps me see the patient from a holistic perspective and to understand that things may have happened in their lives that shaped their outlook and responses to life. I strive to create a comfortable environment for my patients, so they feel safe sharing their symptoms and story with me.”
