What People Say About Dr. John Wiley, MD

Dr. Wiley is simply the best doctor. He thinks out of the box and he is very compassionate. I actually look forward to our appointments. Am I completely healed, no, but he has tried everything and continues to do so. Some patients are complicated, me! He helps me remain positive as I struggle with taking in food for 7 years. He makes me think, a doc/patient relationship is a 2 way street. Patients need to be fully engaged to work with Dr. Wiley on their treatment plan to get closer to healing.

Had a list of questions and a tracking calender. Doc showed zero interest in nu calendar. Answered each question with a question. Basically told me he don't know what is wrong and scheduled me 1 test and told his staff to schedule me with his NP in 6 months. I waited 6 months for answers and help to wait 6 more months. After stating he was referring me to colleges who specialize in IBD only. Maybe in 6 months?? Who knows. No point asking another question. Fingers crossed it ain't serious

Dr. Wiley is very knowledgeable. I have no issues with his clinical skills. However, don't expect to get a return call from his office, even if it is urgent. Multiple times they have failed to return my call and it often takes days to get an answer to your question. Unacceptable.
