Company History 2017-12-29T18:25:46+00:00


Formed in 1994, by John Wheaton, P.E., LEED AP BD+C, and Richard Sprague, WS is a professional services company with a staff of designers, consultants, engineers, and LEED AP’s, with technical focus on building facades, building envelopes, and custom and standard curtain wall systems.

Steady and strategic growth ensued throughout the years as Wheaton Sprague’s reputation and staff grew to accomodate larger projects.

In 2008, in response to increased client demand for expert knowledge of building envelope systems, and the desire to be a complete building envelope specialty company, WS formed a Building Envelope Consulting Division. Mark Coulis, a highly qualified senior design consultant with a distinguished career in the building envelope consulting field, was appointed as Vice President.

The BEC Division advises architects, owners, and related clients on all matters related to curtain wall and other exterior cladding systems and system design, solving complicated design problems and providing workable solutions.

WS added a Minnesota branch in 2010 which was expanded and moved to a more accommodating space in the Fall of 2012. Also in 2012, Wheaton Building Envelope, PLLC, (WBE), a separate, but affiliated company authorized to do business in the State of North Carolina, was created to provide professional services for North Carolina based clients and North Carolina projects.  WBE PLLC is led by North Carolina PE’s, Craig Mertz, and John L. Wheaton. This office was expanded and moved in the summer of 2013 to a larger space in Cary.

The addition of Michael K. Smith, RA, RRC, RCI as Design Consultant to the Building Envelope Consulting Division, afforded WS with the opportunity to expand yet again to an office in Cincinnati, OH in early 2015.

Headquarters in Stow, OH is bursting at the seams, so a construction project has commenced in 2016.

Presently, with a staff of designers, consultants, engineers, and LEED AP’s, that exceeds 40 professionals, the company is poised for continued growth and expertise with consultants servicing projects and clients in any of the WS Office regions throughout the U.S. and around the globe.
