I had a couple of issues that I didn't add while making my initial appointment, but didn't feel rushed at all. Dr. Maddox even gave me a referral.

I couldn't ask for a better doctor. Dr. Maddox always takes the time to understand the issue, share his expertise while including me in the discussion, and makes sure I understand next steps fully. What a great guy
