Russell L. Clark has extensive real estate brokerage experience.
As one of the founders of Grandmark Realty, Inc.,
he brings innovative insight to the commercial real estate
business. Mr. Clark began his
career while a college student, in 1970, as one of the youngest licensed brokers in the state.

Subsequently, in the real estate business, as the principal owner of four
real estate corporations with five residential brokerage offices in metropolitan Oklahoma City, he gained
valuable entrepreneurial
expertise. His background
includes academic and “real world” experience, with an
MBA degree and his study as a PhD candidate.

Additionally, his professional background includes
business consulting and teaching university courses in
marketing, management, and finance. He enjoys family
time with his wife and their children, and sharing his
lifetime interest in aviation with those less fortunate
souls who possess no easy exit plan.
