I can't say enough good about Dr. Hughes. He thoroughly understands my medical history and was totally up to date on my recent scans. He listened to all of my concerns and took steps to follow up on them. So patient with me. He made me feel like I was the only thing on his mind.

Dr. Hughes has a wonderful bedside manner. He was kind, considering this was my first time meeting him. Dr. Hughes was very patient and he took his time getting to know how I felt. He is very knowledgeable and he gave me good advice about my issues and reassured me that he was eager to be my PC doctor. He informed me of several new tests that I had never had and I appreciated that. I felt so good after I left his care. I would give Dr. Hughes 20 stars if I could because he is that good!
