In the beginning…
In 1987, the forerunner of GUY Engineering Services, Willard Engineering, was founded on hydrology and hydraulics (“H&H”) contracts for the Tulsa District Army Corp of Engineers. Stream modeling, reservoir in-flow, hydro-power installation evaluations, reservoir water control manuals, sediment surveys, and river forecast models were some of the early projects. Work partners included Mark Swift, Janet Meshek, Monty Karns, and Bill Blackard. Julie Guy joined Willard Engineering in 1987.
1988: County bridge design work begins
In 1988, Mark, Monty, Julie, and Bill bought out Troy Willard and we became Swift, Karns & Guy Engineers, Inc. as Julie drew the short straw. H&H work for the Corps of Engineers continued for several years. Bill Blackard guided the bookkeeping requirements and closed the books monthly until 2009. We also started doing small drainage projects for the City of Tulsa. Monty marketed County work since his background included work for ODOT. County bridge design was a natural fit for our H&H background.
1990: Bridge inspections and more counties
In 1990, Mark and Julie bought out Monty’s interests and we became Swift & Guy Engineers, Inc. City of Tulsa street maintenance projects, county bridge design for Mayes and Nowata counties, and off-system bridge inspection for Nowata, Osage and Craig counties were our work staples. We performed this work with a staff of five people, with Mark and Julie sharing the bridge inspection duties. Our clients liked our small firm and the fact that everyone could answer questions on the status of their project. ODOT Local Government liked the detailed plans we prepared as we learned the “ODOT way” of plan preparation.
1996: New name and new office
In 1996, Mark and Julie recognized that they each had different goals in business and decided to part ways. GUY Engineering Services was formed and continued to pursue transportation work, including utility relocation management. In 1997, Julie Guy and Jim Harden founded Harden & Associates Surveying and Mapping. In 1998, the office building at 10759 E. Admiral was purchased and we moved out of downtown Tulsa. GUY and Harden shared office space until 2004. Julie sold her interest in Harden & Associates in 2005.
2006: Survey department is formed
2012 and beyond: Acquisitions and ownership changes
In 2012, GUY acquired Perez Engineering of Edmond, and began working in Washington, Choctaw, Bryan, Leflore, Pittsburg, and Pushmataha counties.
In 2014, GUY became an ESOP, an employee-owned company, with the employees joining in ownership with Julie Guy and John Blickensderfer. With this change, Julie became semi-retired and John was named President. Julie remained involved in the company as a part-time employee and led the corporations as the Chairman of the Board of Directors.
In 2015, Julie sold her remaining interest in the company to John. From 2015-2020, John owned 51% of the company and was both President and Chairman of the Board of Directors. The employee ESOP owned the remaining 49% of the company.
In 2020, John sold his 51% of the company to Rebecca Alvarez, making GUY a woman-owned small business again as well as a Native American owned business.
