"My visit with Dr. Andrew Collins wa unique in that I haven't been to a Dr. with such professionalism and caring of a patient in many years. Dr. Collins was so caring compassionate and informative that I was so impressed. He took his time with me and was patient with me as I was very nervous. The whole experience from the time I entered the office until I left left me very calm and reassured. I would highly recommend Dr. Collins to any who needed his type of services. Gaye Karlin"
