Dr. Greenawalt is a truly gifted healer. Everything the other reviews say about him is spot on. My pinched nerve is no longer a problem also I have brought my daughter to see him and he totally corrected an issue none of the other Doctors had a clue what to do with. Needless to say they were going to run a ton of expensive and scary tests on her. As for the appointments, my daughter and I book two and go in together for both. Also he is that Doctor that cares enough to take an extra minute with you if you need it - those add up during the day so if you're time sensitive always shoot for one of the first appointments of the morning or right after lunch.
