I had my breast reduction performed a year ago and am delighted with the results. Dr. Mahoney is kind, patient, knowledgeable and a skilled surgeon. I was extremely anxious to get the surgery, but after years of shoulder and neck pain and carrying very large pendulous breasts on my small frame, I was eager to do the procedure. I did have to pay out of pocket for side liposuction, but Mahoney clearly explained why it was pertinent for the pleasant aesthetics of my chest. I would highly suggest that you be patient and wait to see this amazing surgeon. She is extremely busy; numerous times my appointment and surgery dates got changed. However, it was well worth the wait!! Thanks to the entire team!! I am very grateful for my smaller chest! It has made a significant difference in my life.

I feel incredibly lucky and grateful to have had Dr. Mahoney as my breast surgeon. From the very first appointment, she was everything I could have hoped for and more !so pleasant, so kind, so smart, and unbelievably reassuring. She made a very difficult time feel a little easier with her calm, compassionate presence. Her communication was always clear and comforting, and I knew I was in the best hands. Dr. Mahoney did an amazing job with my surgery. I truly have no words to express how thankful I am for her skill, her care, and her support throughout this journey. She is, without a doubt, one of the best doctors I’ve ever met. Thank you, Dr. Mahoney, from the bottom of my heart!

I cannot express enough gratitude for Dr. Mahoney and the incredible care she provided. From the very first consultation, she has been incredibly kind, compassionate and attentive. I was very nervous about my surgery and her warmth and understanding immediately put me at ease. Her skill and dedication played a critical role in helping me heal — not just physically, but emotionally as well. I will be forever grateful to Dr. Mahoney.

Dr. Mahoney is a fantastic doctor with excellent communication, people skills and bedside manners. She made me feel comfortable to want to work with her, when I was left without a plastic surgeon to fulfill the rest of my much needed recovery plan on expansion removal and implant insertion. She has been nothing but supportive and amazing throughout this entire process and even here after. She has a great team as her entire staff are very welcoming. If you have the pleasure of being tended by her, then rest assure you are in great hands!
