Meet Dr. Sneed

I love meeting and getting to know people, and leveraging UCSF expertise to treat the problem that brought them here.

Dr. Sneed is a senior Radiation Oncologist at UCSF who specializes in radiotherapy and radiosurgery for brain metastases and various primary brain tumors. She earned a summa cum laude undergraduate degree in Electrical Engineering from the University of Missouri in 1976, graduated from Stanford Medical School in 1981, and did her Radiation Oncology residency and a one-year research fellowship at UCSF, joining the faculty in 1986. She officially retired as of July 2018 and then returned in August 2018 as a recalled faculty member, working 43% time. She has tremendous expertise in Gamma Knife radiosurgery–dating back to January 1992–for brain metastases, meningiomas, schwannomas, pituitary adenomas, arteriovenous malformations, trigeminal neuralgia, and other conditions. She greatly enjoys interacting with patients and their families and working with multidisciplinary colleagues and trainees.
