Dr. Larsen has specific training with nerve preservation and resensation at the time of breast surgery.

"I cannot say enough positive things about Dr. Larsen. He is, without a doubt, the best doctor I have ever had. His bedside manner is exceptional—he is kind, patient, and truly compassionate. He takes the time to thoroughly explain everything, ensuring I understand my options and feel empowered in my care. No question ever feels rushed or dismissed, and he approaches every conversation with a level of humanness and empathy that is rare in medicine. Most importantly, I feel safe under his care, something I have never experienced with any other doctor. I always leave my appointments feeling heard and cared for. I only wish all my doctors were like him!"

"If I could give 10 stars to this office and practice, I would! From the moment you walk in, you're greeted with respect. The nurses are thoughtful and put you at ease. Dr. Larsen is absolutely wonderful. He's attentive, knowledgeable and really takes the time to explain results and made me feel so at ease. I was comfortable asking him any questions or concerns. Excellent bed-side manners. Test and follow-ups are planned ahead of time at every visit, and the front desk assists in the scheduling!"

"Dr. Larsen is probably the kindest, most caring and respectful doctor I have ever met or gone to. And I have many doctors! He put me at ease right away and allowed me to put my aunt on the phone in the office while explaining to me, in very understandable and layman’s terms, the results of my testing and imagery. Otherwise I would have been all alone and was afraid I wouldn’t understand what the diagnosis or explanation for anything was. And he spoke to her as well right over the phone and explained everything in clear detail and always asked if we had any questions or concerns. He even recommended a new OBGYN for me as well after I asked for one. And the staff that you speak to and who help behind the front desks were just as helpful and supportive. So understanding. And to top it all off I didn’t have to wait long at all either in the waiting room or the examination room. I was basically in and out. However there was no rushing at all. They were just very proficient and timely. Would recommend Dr. Larsen and his practice to anyone who has to go through such a stressful situation. If I could give ten stars I would."
