Biography & Education

I choose to approach the diagnosis and management of breast disease as part of a multidisciplinary team, in partnership with an informed patient. My role is to educate the patient on all her options and help her make decisions that reflect her priorities. My special interests include • young and high-risk patients • male breast cancer • the interplay of breast cancer with lactation and pregnancy • surgical approaches which maximize the cosmetic appearance of the breast and, in younger women, preserve the ability to breastfeed • skin-sparing and nipple-sparing mastectomies when appropriate for the patient

Patient Ratings and Comments
About Our Survey

The Patient Rating score is based on responses given during the CAHPS Patient Experience Survey. Responses are measured on a 10-point scale, with 10 being the best score. These scores are then translated to a 5-point scale in order to display results in a 5-star rating. Comments are also gathered from the same survey and displayed in their entirety with the exception of any language that may be considered slander, libel or contain private health information, which will be removed prior to publishing the comments.

I have recommended Dr. Tierney to friends and have also bragged about having the best breast surgeon in the world. I have had great feedback from my massage therapist, radiation therapists, and any of the mammogram therapists.
