I would like to go from A cup to D cup...can you help me find a surgeon?

Keep looking and try to understand there are limitations to amount of volume that your breasts can hold.... 

It certainly sounds like you are unhappy with the first surgeon, so why not see another 1 or 2 plastic surgeons before making a decision.  Much depends on your dimensions, how much breast tissue you have, have you had any children etc.  I am not a big fan of the axillary approach with silicone, but that's a personal choice.  Go on several more consultations including one that may have 3-D imaging to see how you might look.  Good luck, Dr. Schuster from Boca Raton.
