Who We Are

Challenge Design Innovations (CDI) was established 40 years ago by Jim Wall, who built his first ropes course and zip line with the belief that quality products and services stem from strong relationships.

The company, originally called Walls Outdoor Associates, evolved over the years and is now owned by Jim's son, Corey Wall, and staffed by industry leaders with extensive experience.

Partnering with CDI assures that your best interests are always at the forefront.
