About RK&K

Since our founding in 1923, the RK&K team has satisfied both public and private sector clients by providing multi-discipline planning, engineering, environmental, and construction services. RK&K's technical expertise places us 73rd on the Engineering News Record's 2015 listing of the Top 500 Design Firms. Our award-winning and diversified staff is experienced in an array of planning and design disciplines. Every one of our nearly 1,000 team members understands what it takes to deliver success to our clients: Responsive People and Creative Solutions.


Our Team Works

Our Team Works

"Teamwork is working together — even when apart."

At the heart of RK&K's success is the high value placed on teamwork and collaboration. Teamwork is important to RK&K's partners and senior leadership and is reflected in the operation of the firm, our projects and our culture. Although RK&K has many offices throughout the eastern United States and Texas, the firm functions as one. We do not have multiple profit centers nor do we encourage "silo" building. Our leaders and their teams do what it takes to achieve a successful project and satisfied client. Whether that means helping out another department or another office in another state, teamwork is the name of our game.

Our "pull together" mentality isn't limited to RK&K employees working on RK&K projects. We have a reputation for developing successful teaming relationships with joint venture partners, subconsultants, design-build contractors, and, of course, our clients!
