Leaders in

Government Relations & Public Affairs 


Strategic Planning

Policy success takes more than passion; it requires 

dedicated planning and meticulous execution. At MAC, we collaborate with our clients to tailor strategies that uniquely fit their organizational goals, combining social media and grassroots outreach with direct contact with decision makers.

Direct Lobbying

At MAC, we specialize in direct and constant interaction with influence makers because we believe the best relationships are built in person. It's hard to see eye-to-eye if you never meet face-to-face, so we are constantly in front of decision makers in DC.

Congressional Fly-ins

Whether your group consists of 15 executives or 1,500 activists, MAC can help with every aspect of your DC fly-in. From speakers to scheduling meetings to activist training, when your membership is on Capitol Hill, MAC has your back.

Coalition Building

Even the most-independent organization will sometimes find itself with common allies in a policy fight. MAC has helped build strong coalitions on healthcare, trade, transportation and taxes, and can help your organization coordinate efforts with likeminded groups on common issues. 

PAC Strategy

With finite political resources, the best-run Political Action Committees are efficient and effective. MAC can help put together a plan and strategy to help your organization get the biggest bang for its political buck.

Strategic Communications

In this age of heightened partisanship and shrinking attention spans, the use of social and digital media platforms are more critical than ever. From whiteboard animations to social media campaigns to influence videos, MAC will help craft the precise message for your exact audience.

Brian Kerkhoven


Brian Kerkhoven, a seasoned Capitol Hill veteran turned clean energy and labor advocate, has joined McCarthy Advanced Consulting (MAC) to provide energy, labor and infrastructure subject matter expertise. Brian joins MAC after seven years leading energy policy for North America’s Building Trades Unions. A relentless advocate for good-paying, unionized, American jobs in the energy sector, Brian has advised companies and trade groups of all sizes as they try to thread environmental and energy policy through the needle of project development and labor strategy. 


Along with his notable experience working in organized labor, Brian’s knowledge of the cleantech space (renewables, carbon mitigation, nuclear, offshore wind, and energy infrastructure), along with the oil and gas industry, provides MAC clients with a unique perspective as our nation transitions from traditional forms of energy. 


Known for his straight-shooting approach, Brian’s background includes nearly a decade of service on Capitol Hill as Legislative Director for Representative Mike Kelly (R-PA), a Ways & Means Committee member, and on the legislative staff for his hometown Congressman, Jim Walsh (R-NY), a former House Appropriations Cardinal. 


Between his two stints on Capitol Hill, Brian spent time as a cleantech energy analyst for a Wall Street investment bank. While at R.W. Baird, he helped expanded the firm’s coverage into key energy sectors, including hydraulic fracturing, electric vehicles, and renewable fuels for clients and sell-side analysts, bankers and sales teams. Brian’s unique experiences allow him to effectively decipher a wide range of interests for MAC’s clients.


Outside of work, Brian can be found skiing, golfing, and tinkering around in his woodshop. He is a proud native Western New York who received his degree in Business Administration from Colby-Sawyer College in New Hampshire. Brian now resides in Olney, MD with his wife and young daughter.

Overseeing all financial aspects of the firm, including invoicing and payroll, Richette brings a level of reliability and professionalism that have become a hallmark of MAC's financial operations.

Before joining MAC, Richette spent more than a decade at Greener & Hook, a premier Washington-based strategic communications agency. Upon her arrival, she immediately put her organizational and management experience to use streamlining and improving the day-to-day office operations. As a result of her efforts, agency clients and strategic partners, including high-profile political and corporate clients, came to know her as a key member of the G&H team.


Richette came to the Washington, D.C. area in 2001 to work for Rothfuss Engineering Company in Jessup, MD. As the administrative assistant for the engineering firm, she was responsible for supporting the engineering consultants and clientele, as well as finalizing all company reports.
