Care Philosophy

I am a board certified General Surgeon whose area of interest is laparoscopic surgery, hernia surgery, and diseases of the breast. My philosophy is to inform the patient of their condition, "the more you know, the better off you are", making certain every patient understands the surgical procedure, options and risks. I make sure what they can expect after any procedure or what they can effect if a procedure is not necessary.
