My first visit with a new doctor, with my previous one retiring after 30+ years with me. Found Dr. Coll to be most pleasant, well-informed on my history, and I look forward, with confidence, to have him care for me.

Always a wonderful experience. Office staff and nurse super nice. Dr. Coll always spends ample time with me and explains everything.
