About

At CRISSP Physical Longevity Clinic in San Francisco, Dr. Kunj Patel and Dr. Rachita Navara deliver advanced care spanning longevity medicine, regenerative medicine, and pain management. The practice name stands for Center for Rejuvenation, Interventions for Senescence, and Strategies for Physical Longevity. That mission shapes every clinical decision the team makes.

The clinic draws on a wide diagnostic toolkit. Cardiopulmonary fitness testing, VO2 max assessment, whole genome sequencing, and advanced imaging interpretation all inform individualized care plans. Treatments range from lifestyle and dietary interventions to PRP injections, orthobiologics, and minimally invasive spinal procedures. The practice has worked with professional athletes from the St. Louis Cardinals, Atlanta Braves, and Atlanta Hawks, as well as performers from Cirque du Soleil. Remote patient monitoring lets patients transmit blood pressure, weight, and heart rhythm data directly to the clinic. Longevity shared medical appointments run via Zoom for patients who prefer a virtual format.
