Dr. Peterson was wonderful.
January 2025
Dr. Peterson is an amazing, compassionate doctor, whom explained everything in detail. He listened to all of my concerns, answered all of my questions. I was very emotional at the appointment and he held my hand and told me how he will help me through my journey. I could not have asked for a better physician. My Son who came with me and I were extremely pleased and grateful for the time spent with him. I would highly recommend him to anyone. I felt very comfortable with him after meeting him
