Carolyn Seen, MD

Primary Care

Read Bio

After graduating from Dartmouth Medical School, Carolyn came to the Bay Area to do her internship/residency at California Pacific Medical Center. She has enjoyed a marvelous medical odyssey which has given her opportunities to practice in both the outpatient and inpatient settings. The breadth of this experience has resulted in a deepened appreciation for the social, emotional, physical and cultural nuances that make each patient’s story unique. Carolyn is an empathic listener who renews her goal each day to be better, to do better. While she marvels at the promise of emerging therapeutics and technologies to improve the quality of
people’s daily lives and to transform health care delivery systems, she remains firmly grounded in the “old school” truism, perhaps most famously stated by Sir William Osler, that “it is much more important to know what sort of a patient has a disease than what sort of a disease a patient has.” The approach of coordinating services in an accessible fashion is not only sensible, butnecessary. Thus, it is with great excitement that the adventure continues in the healing spaces at Crossover. Among Carolyn’s favorite mindfulness activities are: singing with the choir and practicing on her yoga mat. And, of course, for finding her center, she is found happily throwing at the potter’s wheel!
