Leaders in the area of Upper Cervical (UC) Chiropractic care are gathering in Las Vegas, for the UC Evolution conference, taking place at the Green Valley Ranch Resort, Spa and Casino, April 16 – April 18, 2009. While there are hundreds of techniques taught to chiropractors worldwide, UC approaches to care focus primarily on the upper two first vertebra in the neck. Vegas is almost always a great place for a conference.
