My wife swears by this place. I've never had back problems, so have less use for it, but did have good results with some shoe inserts they recommended for chronic foot pain that subsequently disappeared. Per the one-star review below, in my experience, no, they're not terribly professional - If you're looking for someplace cold and clinical, this is definitely not the place for you; they have more of a laid-back, family-friendly, mom-n-pop approach, which I consider part of its appeal.
Pros: Dr Steve is very personable and easy to talk to
Cons: Friendly manner may be considered unprofessional, free consultations can be a bit of a hard-sell
