Dr. Jamie M. Nuwer, M.D. / RegenCore Method Creator

Sports Medicine Specialist located in Palo Alto,  CA

Jamie Nuwer, M.D. is a lifetime resident of California. She fell in love with the Bay Area while attending college at Stanford University. Jamie returned to her hometown of Los Angeles for medical school at UCLA.

She returned to the Bay Area for residency in Family Medicine and fellowship in Sports Medicine at O’Connor Hospital in San Jose. There she was able to cover local sports teams including San Jose State and the Women’s Pro Soccer team, FC Gold Pride. She has continued her research in sports medicine injuries in Ultimate Frisbee. Dr. Nuwer also currently sits as the Chairwoman of both the national and international medical and anti-doping committees for Ultimate Frisbee.

Over the recent years, Dr. Nuwer took great interest in stem cell research and Regenerative Medicine. This quickly became her main area of focus. She has personally helped 100’s of patients in the last year alone regain function and a better quality of life through RegenCore‘s safe and effective Regenerative Therapy approach.  She is currently producing a research paper of her own on this cutting-edge medical treatment.

As a former competitive athlete, Dr. Nuwer had an old knee injury that she had treated with the same exact process that she uses in her office today. Needless to say, her injury had significantly improved, but more importantly, this had given her direct experience of the RegenCore process.

Outside of medicine, Dr. Nuwer enjoys time with her family, friends, and dog Montana. She also enjoys ultimate Frisbee, cycling, softball, outdoor recreation, cooking, and traveling. She recently won the World Championship coaching the USA under-19 girls ultimate Frisbee team. She currently coaches the women’s club ultimate Frisbee team at Stanford University.
