Origins of Clyde Wilber LLC

In 2011 after 37 years of service to Greeley and Hansen LLC including serving on the Board of Directors and running the firm’s Washington DC operations, Clyde Wilber  decided that he would like to devote more time to solving complex technical, regulatory and planning challenges and less time assisting in the management and operation of a large engineering consulting firm.    To facilitate this, Clyde formed his own engineering and management services company (Clyde Wilber LLC). He continues his long-standing relationship with Greeley and Hansen.
