Professional Statement
I am the Richard M. Kleberg, Sr. Professor and Chair of Family and Community Medicine (FCM) at Baylor College of Medicine. FCM is dedicated to continually improving primary care services through comprehensive training and research. I am committed to working with various teams on lung cancer prevention and screening, tobacco cessation, alcohol and opiate use disorders, community engagement, antibiotic stewardship, and physician and researcher training. I further oversee FCM faculty and staff who provide exceptional patient care across numerous private clinics and centers throughout Greater Houston. We also prioritize educating and mentoring our residents, fellows, and medical students interested in family medicine.Websites
