About White Surveying Company:

White Surveying was established in 1940 by W. Kirk White. Kirk grew the business until his death in 1956, after which his family formed a partnership with Earl Denton. The company was renamed Denton & White Surveying.

Upon Earl’s death in 1964, Kirk’s widow, Lorraine White, and his son, David C. White, established a partnership and returned the company to its original name. Following Lorraine’s death in 1975, David became the sole owner of White Surveying.

Paula Koehn and John Libby moved from the Dallas/Fort Worth area to Tulsa in 2013 to be closer to family and founded Route 66 Surveying. About the time it became obvious they needed to make a major step up in size to continue to serve their growing client base, Paula and John learned about the possibility of acquiring White Surveying Company.

With its 80-year history, long-time loyal employees, and deep ties to the community, Paula and John decided this was an opportunity they had to take advantage of. In September of 2020 they purchased White Surveying from David White.
