I have been treated by several dermatologists in my time, in another state. The last one was a skin cancer specialist, and she recommended Dr. Liotta to me when I moved to Maryland. They had found one basal cell skin cancer on me, and I have to get checked yearly. Dr. Liotta was competent, thorough, sensible, and courteous. And so was her staff. She found a site that was pre-cancerous, and she quickly prevented that one. She found a fairly large basal cell cancer on the back of my upper arm, and was very accommodating to my needs during the necessary small surgical procedure. I am allergic to the usual antibiotics, so they questioned me carefully to find one I could tolerate. When my surgical site seemed a little too pink, they found an opening that day, and again they carefully questioned me to adjust the medication . Furthermore, when I later found a small spot on my hand that had been obscured by a bad bruise at my first appointment, Dr. Liotta's staff found a time within two days, and Dr. Liotta spent time explaining how this was different from a spot of basal cell cancer. The doctor and her staff were nice at this return visit even though my payment, mailed a few days earlier, had not yet reached them.
