Dr. Maddox is the most fantastic physician I've had the pleasure of interacting with. My wife and I both work in healthcare and have had experiences with thousands of physicians. Dr. Maddox stands out. He is kind, caring, thorough, intelligent. He is everything you could want in a physician.

I almost never do these reviews, but Dr. Maddox is just such an amazing pediatrician. He is so patient and well-mannered with KIST, but at the same time, so amazing. He always remembers us. It's clear he's looked at the kids' charts. And he's also just so amazing at figuring out what's going on and helping out. Yeah, he's just an amazing pediatrician.
