R.D. Sewald | Co-founder & Principal

The co-founder of Sewald Hanfling, RD Sewald works with Josh Hanfling to chart the course for the firm and to ensure every client engagement has the bold, strategic and outcomes-driven approach that has defined Sewald’s 30 years in state and local government. RD’s deep connections in the community and his vision for the possible are key factors in the results he consistently delivers for clients. From efforts to modernize and restructure regional cooperation to support some of Colorado’s most prized community assets to fostering business environments that allow new businesses to thrive and positioning Colorado as a national and global leader for the future economy, RD has led some of the firm’s most impactful engagements. His skills navigating complex political and regulatory environments led 5280 to include him among the Power List’s Rising Stars.

When it came time to look to the future, Adams County officials looked to RD’s expertise and vision as they sought FAA approval for Spaceport Colorado. In August of 2018, with the issuance of its operators license, Colorado became one of only 11th facilities of its kind, setting the stage for continued growth of the robust aerospace industry in Colorado. In 2013, RD was instrumental in the firm’s efforts on behalf of Uber and creating a regulatory environment that allowed the growing business to operate and create jobs for thousands of Coloradans. These successes on behalf of clients come from RD’s understanding of Colorado’s long history of leading the way for the nation through the community’s frontier spirit and his experience navigating complex regulatory environments. RD also understands the value of some of Colorado’s most loved institutions and the need to ensure they have the foundations to grow into the future. In 2018, he worked with the Denver City Council to create the Metropolitan Football Stadium District, navigating the political and financial challenges of crafting the District that includes all or part of the seven counties in the Denver metropolitan area and establishes long-term strategies for the management and growth of the home of the Denver Broncos.

RD’s ability to craft effective strategies that deliver results for Sewald Hanfling clients and his leadership of the firm’s growth is built on his decades of experience inside local and state government. Prior to founding Sewald Hanfling in 2012, he was the Senior Strategic Advisor and Director of Government Affairs for Colorado’s Governor John Hickenlooper. Drawing on his skills bridging divides between stakeholders and building consensus, RD served as one of the Governor’s primary relationship managers among state and local elected officials, government agencies, community boards and a wide range of stakeholders. RD’s trusted position representing Governor Hickenlooper in the community was a continuation of the role he previously served in as then  Mayor Hickenlooper’s Council Liaison where he was responsible for all contracts and ordinances going through Denver City Council, monitored and evaluated legislative actions for the administration and was responsible for the administration’s legislative team. During his time in the Mayor’s office, RD was the Mayor’s lead on the zoning rewrite and redesign, setting the foundation for Denver’s balanced and robust growth.

Sewald has more than 20 years of experience in state and local government with an emphasis on public policy and political management. Before his mayoral appointment, Sewald was the Director of Government and Community Affairs for the Denver Auditor’s Office, appointed by Auditor Dennis Gallagher. He also was the Deputy Director of Denver’s Planning Department and Zoning Enforcement for the Webb Administration and worked as Director of Neighborhood Inspection Services from 1998 to 2002.

Sewald’s political experience includes work on several campaigns, including Roy Romer for Colorado Governor in 1994, Wellington Webb for Denver Mayor in 1995, Denis Gallagher for Denver Auditor in 2003, Hickenlooper for Denver Mayor in 2007 and Hickenlooper for Colorado Governor in 2010 and 2014. In 2014 Sewald was tapped as Political Director for Latino Outreach for the state and ran the “Get Out The Vote” effort in the last 60 days of the campaign.

Outside of the office, boardroom and capitol, RD is an active member of the community and makes giving back to the community part of every week. He serves as the varsity lacrosse coach at Denver East High School and as a volunteer lacrosse with Cherry Creek Youth Sports. RD has served as Board of Trustee of The Denver Academy and on dozens of planning committees, boards and non-profit organizations in his community. RD lives in Denver with his wife Abigail and the two have three sons.
