5 out of 5 stars Mommy Makeover

Amazing Dr and amazing experience. Feeling great!

Dr. Kneessy gets 5 stars plus from me. He performed Breast augmentation 10 years ago and they came out beautiful. I went back to him and had them done again to refresh and went a bit larger. Scars are minimal pain not too bad and have to say he was awesome all around. His office staff too was excellent. Im 47 and a mother of 2 and had c-sections 17 and 19 years ago. I'm in great shape and...

5 out of 5 stars Mommy Makeover

43, 4 Kids, Full TT, BA with Mastopexy for slightly tuberous breasts with Allergan 400cc HP Silicone Round unders

Dr Kenneth Kneesey was the first and only consult i had for this procedure. He took alot of time explaining everything that he could do to correct my situation. I learned(and kind of already knew) i had slightly tuberous breasts so to achieve optimum results i'd need a periaeriolar mastopexy. I wanted larger breasts as well so we decided to up the game with some 400cc HP silicone rounds under muscle. It took me two years to finally make the decision and book the consult. During those 2 years i researched docs and actually met some women who had work done by him. The dsoc also beiev it or not had some of his patients call me that had same procedure done to say how much he changed their lives!! His TT incision was low and linear and his patients had very positive feedback about him. Although knowing i could have had this done out of country, i was more comfortable staying in the US for post op concerns etc and could not give up 14 days to be in DR (although i would have gladly done it bc DR is beautiful!) Upon my 2nd and final consult before giving my deposit dr. kneesey took alot of his time once again going over both the TT and BA where we tried on so many sized implants. He had a room full of patients and i had a list of questions. Still he took his time with me. I like that in a doctor and i'm very excited to go for my preop on August 8. Also his patient coordinator Kathy is amazing. So excitied!

Super nervous!! Hoping for more fullness and cleavage. I've always wanted to do this and finally now i've decided it's the time! Currently about A/B is but not really I would like to end up a full C cup. I'm not really sure how many CCs it would take for that from what I already am. I haven't had my Pre-op appointment yet so hopefully I can get a better idea once I do =) It's looking like...
