1 Testimonial for Todd M. Colonna

"Dr. Colonna is excellent. If the option was available, I would give him a five-star plus (“+”) rating. Dr. Colonna is highly knowledgeable, thorough and friendly; and, he clearly and concisely answers questions. Additionally, Dr. Colonna looks at the patient as an individual — one with individual needs and wishes. Equally, if not more important, Dr. Colonna is true to his word. (See the Google advertisement about his dermatology practice.) Dr. Colonna only discusses and prescribes what I need and want. What also stands out in my mind about Dr. Colonna — particularly from my second appointment with him — is his high level of expertise and ability to put you at ease. I was there for a skin biopsy. It took Dr. Colonna only minutes to collect the skin sample and I didn’t feel a thing — no stinging or pinching. In fact, he collected the skin sample before I knew it. Afterwards, he clearly outlined the next steps. Dr. Colonna also took the time to get to know and address my individual wishes, needs and worries. He explained that the skin sample he took for the biopsy would not prevent me from engaging in my athletic activities. We also talked about several topics in this brief, but almost fun (I am not kidding), appointment. I have already recommended Dr. Colonna to family and friends."
