Lisa Weissmann, M.D. is an attending physician at Mount Auburn Hospital in Cambridge, Massachusetts, dedicated to breast cancer care, with an appointment at Harvard Medical School. She is the author of numerous articles on oncology, the recipient of many prestigious teaching awards, and a much-sought-after speaker. She can take the driest information — even statistics — and turn it into a fascinating, even funny, talk (a presentation on tamoxifen was applauded long and loud by a transfixed audience). Lisa is a dedicated clinician first and foremost, but her concern for the health of all women has led her to agree to devote time from an overloaded schedule to working for Breastcancer.org, to spread the word to one and all women "who need to know."
