I have a problematic back that rears up every few weeks. Everytime Sean manages to fix my problem. The worst time I put it out so badly that I couldn't sit down for a couple of days (I couldn't get in the car to get to him). Anyway, after a couple of days when I was again able to sit, I walked into their office virtually crippled, and walked out and got into the car unassisted! Very impressed!

Approximate cost: $60
