They use bait and switch tactics. Example your listing is free, then you sign in and it wants credit card information. Total scam. Doctors do not need to be verified by these idiots in order to be great doctors and no doctor on spine health is better than any other doctor. If you want to know about a doctor then look at the state website for discipline. Dont use some third party non chiropractors feeding off the chiropractic profession for their financial gain.
