The Parker Seminars will celebrate a major milestone January 17-20 in Las Vegas. "Celebrating the Past, Exploring the Future" is the theme of the 50th anniversary gathering of more than 8,000 chiropractors, clinical associates and their families at the Rio Suites Hotel and convention center.

Celebrity speakers will include on Dr. Deepak Chopra, world leader in the science of mind-body medicine; Mark Victor Hansen, co-author of the popular "Chicken Soup for the Soul" series; Dr. Wayne Dyer, author and expert in the field of self-empowerment; Morris Goodman, who summarized a story of motivation and courage in "The Miracle Man;" and Dr. Nathaniel Branden, author of "Six Pillars of Self-Esteem."

The seminar will provide four days of presentations by an exceptional line up of chiropractic speakers on subjects crucial to the professional and practical success of the D.C.s and C.A.s as well as activities for spouses and children.

Sharing the spotlight in a half-century celebration of its own will be Foot Levelers, maker of custom-made orthotics that help patients sustain spinal and pelvic alignment.
