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).

"If I could give 10 stars...I would, and even more.
Dr. Larsen and his staff are exceptional!!! The care and genuine concern for their patients far exceeds any office I have been too. Dr. Larsen takes alot of time explaining to his patients what is going on, and what treatments there are to move forward. The delicate nature of what he is discussing is very personal to each individual, and his heart is in it with you. Thank you all for your caring hearts!"

"Our family is incredibly grateful to both Dr. De Resisi and Dr. Larsen for the exceptional care they provided to my mother-in-law during one of the most difficult times in her life. Dr. De Resisi performed a partial mastectomy with incredible skill and compassion. The surgery went smoothly, and we felt confident and reassured throughout the entire process thanks to his expertise and calm demeanor.
Dr. Larsen, the breast surgeon, was equally amazing. After the surgery, my mother-in-law experienced significant pain and discomfort. Dr. Larsen was attentive and responsive, quickly addressing her concerns and draining fluid buildup to relieve her pain. Her compassionate approach made a huge difference in my mother-in-law’s recovery and peace of mind.
We couldn’t have asked for a better team. Their professionalism, kindness, and dedication to patient care truly set them apart. Thank you, Dr. De Resisi and Dr. Larsen, for everything you did for our family."
