I've been a patient for 8 years and have never had a negative experience. Dr. Carroll is highly competent and compassionate. He treats problems aggressively, but he would rather keep you in optimal health. He doesn't over-prescribe nor refer out to a specialist unless it's necessary. His PA Barb is outstanding! She is very compassionate and highly capable. The staff at Renaissance has always been courteous and helpful to me. The wait times are minimal. I don't hesitate to recommend him to others.
