Dr. Pepper is a second-generation family medicine physician with five generations of family roots in the Bay Area. He grew up in Marin and Fresno, where his family moved for his father’s medical training.

He studied Civil and Environmental Engineering at UC Berkeley and is a proud alum of the UC Berkeley–UCSF Joint Medical Program, where his master's thesis mapped the relationship between air quality and asthma. He graduated from UCSF School of Medicine as a member of Alpha Omega Alpha Honors Society and was selected to be a Pisacano Leadership Scholar, which recognizes future leaders in family medicine. He completed his residency training at UCSF, caring for an urban, underserved population at San Francisco General Hospital.

Following residency, Dr. Pepper worked as a hospitalist in the East Bay before transitioning to full-time primary care at Panoramic Medicine in Mill Valley, where he managed a panel of 2,500 patients and served as Medical Director.

Throughout Dr. Pepper’s career, he has remained deeply engaged in the Bay Area humanistic medicine movement—serving as UCSF faculty for the Healer's Art course and volunteering as a medical preceptor at UC Berkeley's student-run Suitcase Clinic.

At Marin Family Medicine, Dr. Pepper provides comprehensive primary care with particular interests in preventive medicine and office-based procedures. He is especially drawn to areas of medicine without clear-cut answers—such as reproductive health, addiction medicine, and palliative care—where the patient-provider relationship is central to care.

When not caring for patients, Dr. Pepper can usually be found in his garden, the kitchen, or hiking the trails of Mt. Tam and the High Sierra.

Dr. Angela Mendoza grew up around the kitchen table in a multicultural home in Novato and Petaluma, CA. There she learned that food was the universal language of love and care. She studied the intersections of biology and agriculture, nutrition and environmental sciences at the College of Creative Studies at UC Santa Barbara, and had a short but rewarding career as a pastry chef in Sonoma County. Her passions for food and community health were a natural pivot to the field of family medicine.

Dr. Mendoza is a graduate of the UCSF School of Medicine and the Lifelong Family Medicine Residency Program, a member of the UCSF Family Medicine Educational Alliance. Her training emphasized outpatient medicine, including pediatrics, women’s health and breastfeeding medicine. She has facilitated group medical visits around menopause health and holistic management of chronic disease, and served as a primary care doctor at the Tahoe Forest rural health clinic in Truckee, CA.

At Marin Family Medicine, Dr. Mendoza provides primary care with a particular interest in accompanying patients through transitions in life and health. As a mother of two, she brings deep empathy and lived experience to her work with families, aiming to foster resilience and connection through all of life’s seasons.

Dr. Binstock is a board-certified Family Medicine physician. He is a Marin native and graduated from Redwood High School. He received his Medical Degree from UCSF and his Master's in Health Sciences through the UC Berkeley-UCSF Joint Medical Program. He completed his residency training at Contra Costa Regional Medical Center, which is known for its full-spectrum, community-oriented, and procedurally rigorous family medicine training. He is a graduate of UC Santa Barbara with Highest Honors and Phi Beta Kappa.

Dr. Binstock’s lifelong interests have centered on interdisciplinary and integrative health. His early work in environmental education, small-scale farming, and the study of herbalism and Ayurveda cultivated a deep appreciation for traditional healing systems. He draws from these approaches, alongside his biomedical training, to provide holistic care to each patient.

Before co-founding Marin Family Medicine, Dr. Binstock worked as a hospitalist in rural California settings, including Truckee and Fort Bragg, where he was often the only internist in the hospital. These experiences honed his broad clinical knowledge and procedural skills and shaped his current approach to practicing medicine, which prioritizes evidence-based therapies, partnership, presence and curiosity, and a deep respect for each patient's path toward health.

Dr. Binstock is thrilled to bring his wide-ranging medical expertise home to his community in Marin. He aims to provide relationship-based, preventive, and integrative care that bridges traditional and modern to promote healthful aging. He lives in San Anselmo with his family and feels honored to serve the community that shaped him.

Dr. Lily Barnard moved to San Francisco in 2016 to begin medical training and quickly became rooted in Northern California. She fell in love with the rolling golden hills, rocky sea cliffs, and the relationships she found among healthcare providers with shared values. Over the years, she has built a life in the Bay Area alongside her partner, friends, and the communities that continue to shape her work and sense of home.

She earned her MD degree and completed residency training in Family Medicine at UCSF, where her training emphasized whole-person care and serving patients navigating complex medical and social circumstances. Dr. Barnard was drawn to family medicine because of its breadth and humanity: the opportunity to build long-term relationships, care for people through different stages of life, and support families and chosen families over time.

Dr. Barnard practiced primary care at Marin Community Clinics in San Rafael and at UC Berkeley Student Health for three years, caring for patients with a wide range of acute, chronic, and preventive health needs. She provides care in both English and Spanish. Her clinical interests include pediatrics and adolescent health, women’s health and contraception, and gender-affirming care. She is especially passionate about creating affirming healthcare spaces for LGBTQ+ patients and caring for people whose past experiences with healthcare may have left them feeling unseen or unheard.

She believes good primary care starts with relationships and that meaningful healthcare happens through trust, curiosity, and collaboration. Her approach to care is practical, evidence-based, and grounded in the understanding that health looks different for everyone. Outside of the office, Dr. Barnard enjoys cooking for loved ones, hiking both near and far, and cat parenting (ask me about Potato).
