Chelsea Hardin, MD, FACS
About Me
“I believe that every patient deserves compassionate, quality health care delivered in a timely fashion.”

Dr. Chelsea Hardin is a board-certified general surgeon with a special interest in the surgical treatment of breast cancer. She has had specialty training in placement of accelerated partial breast irradiation (APBI) catheters, skin and nipple-sparing mastectomies, as well as hidden-scar oncoplastic techniques for the surgical management of breast cancer.
Prior to practicing in Portland, Dr. Hardin helped to open and run a breast center in San Diego. She chose to become a surgeon because it gives her the opportunity to use both her mind and her hands to repair a problem for someone who is suffering. She likes being able to offer a solution that helps get a person back to their regular life.
Outside of the office, Dr. Hardin enjoys running, cooking, and being active with her two young children.
