During my first visit to his office, after a consultation about a hip issue, he did a lower back adjustment that seemed pretty hard. But then he did some kind of very sharp, twisting, pushing adjustment to a part of my back that was not hurting when I went in, but caused an intense back spasm as a result. Left in terrible pain. While he and the assistant were kind and concerned, they also blamed my alleged out-of-alignment back. I entered his office with a mild but persistent hip problem and left with an upper back injury that is severe enough to not be able to move. Hard to trust a practice after that - definitely do not recommend.
