Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Outstanding surgeon
Dr. Gillego is not only an outstanding surgeon with a wonderful bedside manner, but she is a really special person as well. From the moment I walked in her office, I felt comfortable and knew I was in good hands. I can’t recommend her enough!!

Exceptional surgeon and most caring doctor
“You are going to be ok” were the first words I heard from Dr Gillego. This set my overall outlook towards the year ahead of me . I have grown to trust my amazing surgeon and am great full to her for the results and care she provided me with.From the time I first met her she has provided me with incredible clarity all the details, facts and options available, I thank her for that. It was the clear facts that helped me make decisions for direction of my care.

Excellent Dr and I highly recommend her.
Dr Gillego has a wonderful, nurse-like bedside manner. This is unusual for a surgeon. But is just what a patient needs when seeing a breast surgeon. She was truly kind, patient & helpful. Throughout the entire experience she made me comfortable. The surgery, an incisional biopsy, went very well and the incision is thin and neat. I very highly recommend Dr Gillego as you will be in great hands under her care.

Wonderful surgeon! Highly recommend
A doctor with skill, expertise and amazing bedside manner can be hard to come by but Dr. Gillego truly has it all! I am so incredibly grateful to have been in her care during my breast cancer journey. Not only did she perform my lumpectomy absolutely flawlessly, she took great care in helping me with all my care procedures with the Yale oncology staff and following up with me to check in every step of the way. When you’re overwhelmed with a cancer diagnosis, this kind of help really goes such a long way. There is no need to look any further once you’ve found Dr. Gillego. She is a life saver in the most literal way and I highly recommend her.

Dedicated, Knowledgeable, Professional, Kind
I am so grateful to Dr. Gillego for her knowledge, professionalism and kindness. I told her from the beginning that she was a second opinion, recommended by a friend; her office was out of state and too far for more than a consult. Still, she spent a lot of time with me, encouraging me to ask questions. After my surgery, Dr. Gillego called me to learn about my recovery. A dedicated surgeon who genuinely cares for each person's well-being, I highly recommend her.

Dr. Gillego is one of the most attentive and thoughtful doctors I have ever met. Last month she performed my lumpectomy to remove DCIS. It was a scary situation to be in but she brought so much knowledge and comfort that I felt that I could trust her immediately and completely. I highly recommend Dr. Gillego as a breast surgeon and would insist upon my family and friends seeing her if the need ever arose.

Dr. Alyssa Gillego is the BEST breast surgeon I have ever met, and I've talked to quite a few over the course of 2 breast cancer occurrences. What makes Dr. Gillego so impressive is her bedside manner and respect for her patients. Furthermore, you walk away from appointments with Dr. Gillego with your dignity and your hope INTACT. She is truly a remarkable medical professional and 5 stars is simply NOT enough to demonstrate how strongly I feel about her practice.

Dr. Gillego is the kindest physician I have ever encountered. I'm very sorry she is leaving for Connecticut at the end of the summer, but patients there will now have the benefit of her high-quality care. Once she saw me on the same day when I had a breast concern. All of the nurses and other helpers were friendly, but her secretary was quite prim and grim.

Dr. Gillego was my surgeon for a mastectomy I recently had and I could not be happier to have been in her care for this surgery. Not only is she very knowledgeable in her field but she has the best bedside manner I have ever seen in a doctor. She was very attentive to me, answered all my questions, took the time to explain everything to me. She performed the surgery flawlessly, she is a true professional, a real doctor who treats you with the care you'd expect from a doctor when you need a ma
