WCM Physician (What is this?)

Personal Statement

I went into primary care primarily because of the opportunity it affords me to develop meaningful relationships with patients as we work together on health and wellness. Whether it's a short visit for a cold, or a years-long longitudinal partnership, I love being able to listen to patients' experiences and use my expertise to work together on developing a diagnostic, treatment, and follow up plan. Working at Weill Cornell, with the incredibly talented and dedicated staff that I am blessed to be able to work with each day, I am able to offer the highest quality, efficient, patient-centered care possible to help patients acheive, or regain, their optimal state of physical, emotional, mental, and spiritual health.
