Dr. Chastain and his staff are top notch and the gold standard for service providers. I had blood work completed (HIV/AIDS/STI) and my HIV results came back as reactive/abnormal. Dr. Chastain immediately called me and talked to me about what the results meant. By the time we talked the second HIV came normal/non-reactive. He reassured me and made sure I was completely informed. He advised me that the first test was most likely a false positive and that a backup sample would be tested and it would determine which one was correct. He assured me he would contact me as soon as the results came in. He ended up contacting me that same night at 9 PM with the results (normal/non-reactive). He is truly amazing and I am glad he is my doctor.
