FDC building might be slightly confusing for anew person and the phone system is not that great but what makes this review 5 stars is Dr Zang. He took the time to listen to me, answer all my questions, and help me come up with a treatment plan that we both agree on without just throwing some pamphlets at me about my disorder and a script. I will continue to see him and am so glad that I have him to be there to answer questions and concerns along the way. Even though a quiet and a man of few words, Fayetteville is lucky to have a specialist like him.
