Greetings to all, My experience has been the opposite of the gentleman in the above review, I regret very much what does sound like a nightmare experience. My son has MoyaMoya disease that has required two brain surgeries by Dr. Mericle and his staff, and both times it went well. And associated tests went well too. We have been to the office and hospital about 6 times for different services and have always been happy with the doctors and the office personnel. We are fortunate to have Dr. Mericle here in Nashville, and to serve patients from around the U.S. charles coryn, lancing, tn.
