Dr Lok is clear about what he can and what he cannot help you with. He is efficient and quick and runs a tight ship in his business. He helped me with a frozen shoulder which turned out to be a torn rotator cuff from an MRI which my orthopedic surgeon states will need surgery. By 2 months of treatments 2-3 times a week I went from unable to raise my right arm more than 1" forward and laterally to having full function. He stated to me that this was a quicker than normal recovery and that normally this nearly frozen shoulder could taken up to 6 months of treatment. His staff has been with him a long time. The office is in an older building. The waiting room seems like your average medical waiting room with very little natural lighting due to lack of windows. Nevertheless I don't go there for ambience. I go for the treatment which is excellent.k
