Get In Touch

I see patients in my office at the Ridley Tree Cancer Center-Sansum Clinic, and operate at the Foothill Surgery Center & Cottage Hospitals in Santa Barbara and Goleta, California. I offer prenatal and postpartum house calls, as well as telemedicine consults .

We are able to utilize your health insurance for these visits.

Katrina B. Mitchell, MD, IBCLC, PMH-C


My name is Katrina Mitchell, and I am a board-certified general surgeon, fellowship-trained breast surgical oncologist, international board certified lactation consultant (IBCLC), and certified perinatal mental health provider (PMH-C).  My practice focuses on the surgical management of benign and malignant breast disease, care of lactating patients, and medication management for perinatal mood and anxiety disorders in collaboration with mental health therapists.  I have a special interest in young women’s breast cancer and patients with cancer that develops during pregnancy or the postpartum period.  I also support lactation in those patients with a history of breast cancer.

I teach a free prenatal class, “Breastfeeding your Baby.” It currently is available remotely and registration is via the Sansum Clinic website

In addition to clinical work, I am active in the American Society of Breast Surgeons and Society of Surgical Oncology. I also collaborate with Academy of Breastfeeding Medicine (ABM), the Institute for the Advancement of Breastfeeding and Lactation Education (IABLE), Postpartum Support International, and local and state breastfeeding organizations.  I contribute to the ABM’s blog, IABLE podcasts, and speak regionally, nationally, and internationally on breast cancer and lactation topics. Locally, I serve as the medical director of Santa Barbara County’s Welcome Every Baby (WEB) visiting nurse program and the Ventura Coast Milk Bank.
