“As a physician leader, I’m a product of the many communities I have served that have changed my life and my perspective over the years: the LGBTQ and undocumented immigrant populations of East Los Angeles; the underserved communities of Pasadena; persons living with HIV throughout Southern California; and intellectually and developmentally disabled patients living in Suffolk County. As a primary care provider who has spent the last fourteen years working in various FQHC settings, I care very much about supporting our providers and staff in sustaining long, healthy, and deeply fulfilling careers in spite of the physically and emotionally challenging work that we engage in; and I have an equal passion for addressing the innumerable barriers to quality healthcare that deepen the suffering and shorten the lives of the patients that we serve. For all these reasons, I am very proud to join Harmony Healthcare Long Island, an organization with a noble mission, an inspiring leadership team, and a proud history of advocating for all of our local communities”.
