About

Amy Bremner, MD, is a breast oncology surgeon at MemorialCare Medical Group in Laguna Hills and is the Medical Director for Breast Surgical Oncology at Saddleback Medical Center. Dr. Bremner completed her medical education at Georgetown University. She went on to complete her residency at Huntington Hospital for general surgery. Following her residency, she completed a fellowship at the University of Southern California for breast oncology.

Growing up, Dr. Bremner knew she wanted to pursue medicine because she was inspired by her father, who was also a physician. She decided to become a breast oncology surgeon because she always enjoyed women’s health, especially treating breast cancer.

As a physician, I enjoy working with my patients from the time of diagnosis to the completion of their treatment. Helping them through their journey and providing them cancer treatment and emotional support brings me the most joy. I want my patients to know I sincerely care about their successful treatment. I am committed to the most current, evidence-based, high-quality cancer care available. I am my patient’s most passionate advocate.

Dr. Bremner grew up in Sacramento, California and speaks Spanish. Outside of medicine, Dr. Bremner enjoys volunteering with her daughter through the National Charity League. She also enjoys working out, watching her children play sports, and traveling the world.

She gave us as much time as we needed, even though we were scheduled for a short appointment due to booking error. She explained things clearly and slightly and gave options.

A True Advocate for Her PatientsDr. Bremner is always professional and personable. She truly cares about her patients and never glosses over questions or concerns. From my very first visit, she has been both thorough and compassionate. It’s clear that she is committed to excellent care and the best possible outcomes for the people she treats.She is also a strong advocate for her patients and goes to bat for them like no one else. With Dr. Bremner on your team, you truly feel that you are not fighting alone. I would recommend her without reservation to anyone facing breast cancer.
