Shannon N. Tierney, MD, MS

Breast Surgeon
Languages: English
Accepting New Patients
Professional Statement
Dr. Tierney is a 2017 Seattle Met Top Doctor Award winner. Philosophy of care: 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

While I'm sure Dr. Tierney is an excellent surgeon, I believe the type of surgery she recommended is in excess of what I need. I'm very concerned that the two reasons she seemed to conclude made this surgery necessary are based on use of less than full info available to her, i.e., I tried to discuss the rest of the info but didn't realize she had concluded otherwise until I went over it in my mind later.

My goodness, what can I say - I appreciated the time Dr. Tierney took to answer all of my questions, as well as those of my sister and my husband. It is not an easy topic to discuss and she made the conversation very comfortable.

Dr. Tierney was recommended to me and I quickly discovered why! She is intelligent & an amazing surgeon. As a bonus - she is absolutely delightful & confident! What a combo.

Dr. Tierney is knowledgeable and caring, with a great sense of humor, and as the adage instructs, laughter is (among) the best medicine(s). She made a scary surgical procedure less scary by listening carefully to my and my mother's questions and concerns. Neither of us felt rushed or intimidated when speaking with Dr. Tierney.


I arrived sad and concerned. I left happy and confident.
