Group Dynamix evolved from the construction of a small indoor ropes course at the Dallas Fun & Fitness Center in 1995. It was called the "Adventure Course" and it quickly became one of the most popular activities for teenage youth groups in the area. The course was unique in several respects. Although built indoors, it modeled a traditional outdoor challenge course. But far from traditional, the vast majority of the programs conducted on it were recreation in nature, a departure from the highly-focused team building and therapeutic programs commonly associated with outdoor challenge courses.
The owners of the Dallas Fun & Fitness Center, brothers Ken and Steve Fleming, joined with Stephen Mackintosh in September of 1997 and formed the business that is now Group Dynamix. At that time, they decided to expand their business to include recreation events and team building programs for corporations and organizations. Since then, Group Dynamix has assembled what many consider to be the best "people, programs and place" in the industry. In the summer of 1998, Group Dynamix moved into its new 13,600 sq. ft. facility in Carrollton expanding to 17,600 sq. ft. in 2008 making it the largest team development center of its kind in the nation.
