Dr. Herrington received his medical degree from the University of Virginia School of Medicine and his master's degree in public health from The Ohio State University. He is dual board-certified in Addiction Medicine and General Preventive Medicine & Public Health — a combination that reflects both his depth of expertise in treating substance use disorders and his commitment to whole-person, population-informed care.
Dr. Herrington served as medical director for several in-person addiction medicine clinics, where he saw first-hand how stigma, visibility, and logistical barriers prevented people from getting care they were ready to receive. His work at Bayani Health & Wellness solves that problem — bringing specialist-level addiction medicine into a private, flexible telehealth model.
Dr. Herrington approaches every patient relationship with the understanding that addiction is a medical condition, not a moral failure. His clinical philosophy is grounded in evidence, delivered with respect, and committed to long-term outcomes rather than short-term compliance.

Dr. David received her medical degree from The Ohio State University College of Medicine and her master's degree in public health from the University of South Florida. Her training spans internal medicine, occupational and environmental medicine, and lifestyle medicine — a breadth that directly informs the whole-person recovery model at Bayani Health & Wellness.
Dr. David brings decades of personal and clinical experience with plant-based nutrition and physical fitness to her practice. She is the founder of Bayani Health & Wellness and the architect of the clinic’s lifestyle medicine component — the nutrition and movement guidance that distinguishes our program from practices that treat addiction with medication alone.
She understands that recovery involves the entire body, not just abstinence from a substance. Her goal for every patient is not just stability, but genuine restoration of physical and mental health.
