Breast Surgery
Dr. Larsen earned his medical degree at the University of California, San Francisco. He completed a general surgery residency at New York Presbyterian-Queens and a fellowship in breast surgical oncology at the Allegheny General Hospital, a large urban facility in Pittsburgh, Pennsylvania.
Similar to many who join this field, the personal experience of having close family members battling breast cancer solidified Dr. Larsen's commitment to serving this patient population. He has worked with diverse populations throughout his career, including time spent in Guatemala and Zimbabwe. He is bilingual, fluent in English and Spanish, and is excited to return to New York City to join NYCBS and provide the highest level of care to its diverse and unique community. Dr. Larsen has specific training with nerve preservation and resensation at the time of breast surgery. Dr. Larsen has experience with several localizing techniques and oncoplastic closures for partial mastectomies. In addition, he performs both electrocautery and tumescence-based mastectomies. He enjoys learning new languages and has traveled to 20 countries (and counting).

"I saw Dr. Larsen as a last minute emergency - he was absolutely phenomenal. He is a skilled doctor with a stellar bedside manner. He went above and beyond! I know few doctors who truly care for their patients the way Dr. Larsen does and would stay late to make sure the patient gets the care they need. I wish I could give him more than five stars!"

"From my very first visit with Dr. Larsen, I knew I could put all my faith and trust in him. He was patient, gentle, friendly, and incredibly knowledgeable. He took the time to break everything down in a way I could truly understand — explaining every detail so clearly that I left his office with complete confidence and peace of mind.
Throughout the entire process, from consultations to surgery, Dr. Larsen made me feel safe and supported. He was exceptionally thoughtful about where he placed my incisions, making sure the scarring would be minimal because he cared about my comfort and self-esteem just as much as my health.
Now, five weeks after surgery, my incision looks clean, precise, and better than I ever expected. I am deeply grateful for the care he provided, and I have absolutely no regrets about trusting him to remove my cancer. Dr. Larsen is truly a gifted surgeon and a compassionate human being. I cannot recommend him enough."
