Happy to inform, I am in remission and my mammograms have been clean. I feel my best decision in finding a qualified surgeon for treatment was when I found Dr. Sigalove. P.S. Staff and timeliness for appointments were also above reproach! Was never in waiting room for more than five minutes!" C. Nelson
