“I found Dr. Shahin to be very straight-forward from the first visit. He is extremely intelligent, kind, understanding, and takes time to answer any and all questions. I had a robotic-assisted hysterectomy from Dr. Shahin and was AMAZED at my healing and recovery time! I feel truly BLESSED to have him as my doctor and would HIGHLY recommend him to anyone in need of his care!”
