“I can do an operation, but the patient is the one who has to do the wound care, the healing, and to manage their nutrition afterwards. So it’s important that we set up a relationship in the beginning and work together as a team.”

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.
