Gary Charles and Associates Salon was opened in 1972 in Philadelphia, PA by Gary and Maureen Muhlberger and has been on the "cutting edge" of the beauty industry ever since. Gary Charles and Associates has been named one of the top World Class Color Salons in the country and has had their work published in various trade and fashion magazines. The salon has been completely departmentalized since 1995.

Maureen created their specialized color department and hired Kristina Rosato, a former L'Oreal technical educator, as the director. The Color department consists of nine professional colorists that have been trained in the latest hair designs and haircoloring techniques. The salon also features a special Bridal department and full service wig center.

In 1997 the salon was expanded to include the Rebel Academy, an advanced training center offering ongoing education for salon owners, hairstylists and beauty manufacturers. By this time the artistic team had already been named by the American Board of Certified Master Colorists and was being listed by Salon Today Magazine as one of the 200 fastest growing salons in the country.
