Dr. Kathryn Pearson Peyton, Women with Heart for October 2017


(Pictured Above: Kathryn Pearson Peyton, MD – Founder, CEO & Chief Medical Officer, Mammosphere, Inc.)

Born in San Francisco and raised in Northern California, Dr. Pearson graduated from Stanford University, followed by medical school, Radiology residency, and Breast Imaging fellowship training at the University of California San Francisco, and was a dedicated breast-imaging radiologist in San Francisco and Jacksonville for 15 years. She is a passionate advocate for women’s health, having personally had 3 generations of her family afflicted with breast cancer. In 2012, she retired from her radiology practice and founded a non-profit technology company, Mammosphere, Inc., that stores and exchanges mammograms and other breast imaging studies in the cloud. This provides immediate patient and physician access to essential prior mammograms, improving the accuracy of mammogram interpretations and thereby resulting in earlier detection of breast cancer while reducing unnecessary additional imaging, follow-up, and biopsies. Mammosphere was acquired by lifeIMAGE, based outside of Boston, in 2016, where she continues to serve as a medical consultant and Chair of the Women’s Health Advisory Board.



Kathryn has been actively involved in the community, serving on the Boards of the Jacksonville Zoo and Gardens, University of Florida Proton Therapy Institute, American Cancer Society, Advisory Board for the Cathedral Arts Project, and member of the Women’s Giving Alliance. In 2009, she was awarded the Girl Scouts of Gateway Council Women of Distinction honor, and she was a Florida-Times Union EVE Award Finalist in 2016. Her passions include anything that involves her two young boys (ages 11 & 9) and husband, John, playing the violin with her Passatempo Trio, reading, yoga, snow skiing, and travel with girlfriends.
