About
Gilberto Hernandez leads Biograph's San Mateo / San Francisco Bay Area clinic as Medical Director. He earned his MD at UCLA, completed a PhD in biology at Caltech focused on gene-regulatory networks in skeletal muscle, then trained in internal medicine at Highland Hospital in Oakland. Before joining Biograph, he spent seven years as an internist at The Permanente Medical Group. That mix of molecular biology, large-system primary care, and personal endurance training gives his preventive work a data-literate but practical frame.
What to Know
Signature approach
Hernandez brings a bench-scientist habit to the results review: treat each result as part of a system, then ask what pattern it creates across imaging, labs, fitness, and history. His Kaiser primary-care years keep the plan grounded in what a person can actually do after the visit, not just what the data reveals.
What sets them apart
- Caltech PhD in biology. His dissertation work on gene-regulatory networks gives him molecular-biology depth uncommon in a preventive clinic director.
- Large-system primary-care experience. Seven years inside The Permanente Medical Group means he has managed chronic disease in a mainstream medical setting before pivoting to preventive diagnostics.
- Endurance-athlete lens. As a triathlete, he can read VO2 max, recovery, and metabolic data with personal familiarity as well as clinical training.
Before You Book
- San Mateo only. Hernandez practices at the San Mateo / SF Bay Area location. New York visits route through Jim Lebret, MD or Yihan Chen, MD, MPH.
- Keep primary care separate. Biograph is a diagnostic and monitoring layer; acute care and routine medication management still belong with a primary care physician.
- Expect a team-based day. Dietitians, exercise physiologists, and technologists deliver parts of the assessment; Hernandez owns the physician synthesis and care plan.
