Jay Hagen

Founder/EVP

DP Guardian’s founder, Jay Hagen, grew up in Mason City, Iowa and graduated from Iowa State University in 1980. Following 12 years in the bustling Southern California marketplace, Jay moved to Colorado in 1992, where he started DP Guardian, filling the need for proper cleaning and maintenance in computer and telecom facilities throughout the western US. As DPG’s first employee, Jay developed the company into a full-scale data center services and products company. He has witnessed the unprecedented evolution of computer facilities and their infrastructure – including technological advances and the skyrocketing cost of downtime – and has continued to innovate solutions to avoid downtime risks. In his spare time, Jay enjoys bicycling, competitive league tennis, and traveling with his wife, Lisa, and his daughter, Vanessa.
