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.

Unhappy with the Results
Fifteen years ago I had breast cancer. I had a mastectomy of my right breast. Dr. Kneessy performed the implant surgery on both breasts. My breasts are NOT symmetrical. My right breast looks like I’ve never had an implant, and now my left one is sagging. They look terrible. I couldn’t bear the thought of another surgery, after all I went through. Dr. Kneessy was very nice, but I would never go to him again.

I recently had to have breast surgery for a ruptured implant that I’ve had for five years. I was terrified to learn these implants have just been recalled and could cause a rare cancer. My situation was complicated for many reasons. Another cosmetic surgeon I saw terrified me even more and I left her office in tears. I called Dr. Kneesy’s office and Virginia answered the phone. I was crying and she was so caring and helpful and so compassionate. She made sure I was able to get an appt that same day. From the moment I met Dr. Kneesy he made me feel so comfortable. He is extremely professional, patient, knowledgeable and caring. He took the time to calm all my fears and answer all my questions (on more than one occasion). On the day of my surgery I was so nervous. The staff gave me hugs. They showed me immense kindness and support. My surgery was flawless. Dr. Kneesy is such a skilled surgeon and I had such peace of mind knowing that I was in good hands. I highly recommend Dr. Kneesy.

BEWARE. I went to dr. Kneessy for a "consult" for breast reduction surgery. I met with him, nice dr it seemed, but not someone I felt entirely comfortable with. I had a second consult with a different doctor, one more personable and thorough, and someone that really listened. Now I have 2 doctors, one I vibed with and dr. Kneessy. After hours of research online, reading reviews and testimonials, I made the best decision and chose the other doctor. Let me tell you, Dr. Kneessys office does NOT take rejection well. His office staff are argumentative and not professional at all. Like little kids stomping their feet because you chose not to go with them. My "free" consultation turned into a $425 bill. Unless you want to throw your money out, just don't bother going through the same headache I am.

I could not recommend Dr. Kneessy more highly. From my first encounter through my complete follow-up I was 100% comfortable and well taken care of. The attention he and his staff paid to me throughout our time together was as if they were taking caring of their own family. He was always interested in my opinions or concerns. Never rushed and fully invested in my experience being the best possible, which it was. Not to mention the wonderful outcome. I'm so grateful to have found him.

Dr. Kenneth Kneesey MD, is the utmost professional and caring doctor I’ve met in a long time. His calm and caring demeanor keeps you feeling confident that you’ve made the right decision and are in the right hands for your surgical needs. The entire staff at Suffolk Plastic Surgeons, the doctors, nurses and administrators are extremely caring and helpful all the same. There is a feeling of family in this practice and this is what separates them from the rest. Thank for your excellence!!Joanne R

Dr. Kneessy performed a Belt Lipectomy with Bilateral Inner Thigh Lift on me on 1/9/18 and I could not be happier with my results so far. I don't have enough words to commend the work of Dr. Kneessy and his staff at Suffolk Plastic Surgeons. Everything that he promised me pre-op, he delivered...and MORE. Dr. Kneessy has incredible bedside manner and makes you feel very comfortable at all times. I will be going back to have an arm lift and breast augmentation and will not use anyone else.
