About
Jim Lebret is Medical Director of Biograph's New York City clinic and an internist board-certified in both internal medicine and lifestyle medicine. He studied neurobiology at Cornell, earned his MD at the University of Minnesota, and trained in internal medicine at New York Presbyterian / Weill Cornell. Before Biograph, he served as Assistant Professor at Icahn School of Medicine at Mount Sinai, Senior Medical Director at Mount Sinai Health System, and practiced in Manhattan concierge and preventive-care settings.
What to Know
Signature approach
Lebret treats nutrition, movement, sleep, stress, and social connection as primary clinical levers, not wellness extras. His lifestyle-medicine training and Manhattan concierge background show up in the results review: dense diagnostic data gets translated into practical next steps a member can act on between visits.
What sets them apart
- Lifestyle medicine board certification. DipABLM gives formal grounding for treating diet, exercise, sleep, stress, and social connection as core medical tools.
- Neurobiology research background. Cornell distinction in research and a co-authored 2003 Science paper give him unusual bench-science depth for a preventive internist.
- Academic plus concierge track. He has worked at Icahn School of Medicine at Mount Sinai, Mount Sinai Health System, and Manhattan concierge practices before leading Biograph New York.
Before You Book
- New York clinic only. Lebret practices at Biograph New York City. The Bay Area clinic is led by Gilberto Hernandez, MD, PhD.
- Shared NYC roster. Yihan Chen, MD, MPH also practices at the New York clinic, so physician assignment depends on scheduling and fit.
- Keep primary care separate. Biograph gives baseline assessment and results review; routine medication management and acute issues still belong with a primary care physician.
- Multi-state licensure. NY, NJ, CT, and CA licensure may matter if follow-up crosses state lines.
