Leadership Team

With over 125 years of combined experience in the design, construction and operations of high availability facilities, alternative energy and telecommunications projects, RPS’s leadership team understand the needs and challenges of facility owners, end users and alternative energy manufactures. As a result, we have a unique stakeholder’s perspective to design, construction and energy conservation by managing costs, reducing risks, and meeting critical project schedules. On every RPS project, we draw upon our knowledge and expertise to drive efficiencies, challenge assumptions and prudently apply capital against legitimate business risk and returns.
