Hamm Consulting Group

What Hamm Consulting Group does

Hamm Consulting Group (HCG) is a privately held, founder-owned federal advocacy and government relations firm founded in approximately 2005 and headquartered at 1717 K Street NW, Suite 900, Washington, D.C. The firm is led by President Ron Hamm and operates with a small team of approximately seven professionals, including a former U.S. Department of Transportation Deputy Director who created the TIGER Discretionary Grant Program (Robert Mariner), a 26-year federal lobbyist with U.S. House, Senate, and White House staff experience (Bill Hanka), and a 35-year Bryce Harlow Scholar federal advocate (Leslie Mozingo of Strategics Consulting, operating as a strategic partner).

HCG provides federal government relations, lobbying and advocacy, government affairs consulting, strategic counsel, federal competitive grants support, federal business development, and legislative and regulatory advocacy services. Engagements are customized quote-based arrangements, typically structured as multi-year contracts, and the firm serves municipal and county governments, higher education institutions, private sector organizations, and natural resources clients across the United States. Documented client outcomes include securing $10.6 million in USDOT RAISE grant funding for the City of Yuma, $10 million for California State University Fullerton's Titan Gateway Pedestrian Bridge, $2.2 million for Cumberland County wastewater infrastructure, $1.25 million for Hennepin County emergency shelter, and facilitating over $100 million in public and private investment for Yuma's waterfront redevelopment over twelve years.

The business model is professional services fee-based, with revenue generated through retained engagements rather than transactional or productized offerings. GTM is consultative and sales-led, leveraging referrals, case studies, a weekly newsletter ('HCG This Week in Washington in 1 Minute'), a Grants Opportunity Alert, partner referrals through Strategics Consulting and Hanka Advisor, and direct outreach to enterprise and government buyers. The firm has no disclosed funding rounds, no parent company, no subsidiaries, and no technology platform; its competitive position is grounded in two decades of relationships with legislators and federal agency officials rather than proprietary technology.
