He has been treating me for over three years now. He is very knowledgeable, kind, thorough, compassionate, professional and refuses to take any possible risks with me when prescribing me my meds. He has helped me immensely and prescribes me exactly what I need to relive my symptoms and treat my conditions. He also encourages me to eat healthy, exercise, take vitamins and use spiritual methods to help to relieve my anxiety, pain and depression. My anxiety, pain and depression are under control now and I feel great thanks to Dr Maddex. He takes his time and answers all my questions and spends time talking with me. He is always available to talk on the phone if I need to talk to him. His office staff are wonderful, organized and always get my prescriptions called in asap. They are all great. Although, I do know he has a ton of patients due to his popularity, I never have to wait more than 10-15 minutes to be seen. He is the best doctor I have ever had. And I have had many over the years.
