Dr. Greenberg is very well known. He is often seen on tv and also has a long island radio show. HOWEVER, I had lipo done by him about 4 years ago (on my love handles, not chest) and was not thrilled w/ the results. Not terrible, but could have been much better.
Also, back when i got the lipo, i had asked him if he could also do my chest. His response was "just work out." In my opinion, this is not someone who is overly knowledgeable w/ gyno.
