Amazing surgeon, human being, professional. Dr. Allen is the best and I would not consider ever going anywhere else. My reconstructive surgery is amazing, and I am forever grateful for his care, kindness, and ability.

Extremely impatient with questions - listened superficially and gave only abbreviated answers. He evidently becomes rather annoyed if asked to provide any explanation to the patient. The sole bad doctor I’ve encountered at MSK over the past 10 years.

Dr Allen was disappointing. After my double mastectomy my healthy right breast dropped 4 inches ower than my left due to the stitches coming out of the breast expander. His response was cold and uncaring, stating that happens sometimes. He offered no apology or remedy. It has been 7 months of pain and I am now seeking my reconstruction at a different hospital. Its a shame thar MSK is not what it once was.

Absolutely love Dr.Allen. Had TNBC and had dmx with prep for reconstruction. Ran into a problem from no fault but my own putting a heating pad on and had to get one expander out because of necrosis. Dr Allen was so patient and understanding and also very funny. Have been seeing him for the last year and half and he was very thorough in his explanations of procedures. Decided to go flat in the long run and explained in full detail what I would go through. His bed side manner is wonderful! The office in Basking Ridge is very efficient and his staff are amazing. I highly recommend Dr. Allen for any type of reconstruction you have to get due to Breast Cancer.

Dr. Allen and his team did a wonderful job reconstructing my breasts after a double mastectomy. The visits to his office were a bright spot in a difficult time in my life. Dr. Allen is attentive and caring. He will take time to explain anything about the procedure and why they do things the way that they do. I always felt like he took my care and my feelings very seriously. I would highly recommend Dr. Allen!
