Concierge Doctor in San Francisco
About Dr. Leah Tessler
Dr. Leah Tessler is a board-certified internal medicine physician offering personalized concierge primary care at Golden Gate Concierge Medicine in San Francisco. With nearly 30 years of experience caring for patients in the Bay Area, her guiding principle has always been to place the patient at the center of every medical decision. Her clinical interests include preventive care and supporting women’s health throughout all stages of life.
Dr. Tessler earned her Bachelor of Science in Biology from UCLA and her medical degree from McGill University in Montreal, where she was born. After moving to San Francisco in 1992, she completed her internship and residency in Internal Medicine at UCSF–Mt. Zion Hospital. She has been continuously board certified in Internal Medicine since 1995.
Dr. Tessler cared for many of the same patients and worked alongside a consistent core group of clinicians for nearly three decades, even as her medical group evolved across different models. Throughout her career, Dr. Tessler has prioritized long-term relationships with her patients—delivering high-quality medical care grounded in clear communication, clinical excellence, and mutual trust. What distinguishes her most is her long-standing presence in the Bay Area medical community and her deep commitment to continuity of care. Her focus has always been on building strong doctor-patient relationships. She prioritizes preventative care and evidence-based medicine. Although she enjoys the intellectual challenge of medicine it was the connection with patients she missed most, and what ultimately drew her back to practice after retiring in 2023.
