Marc Lampkin, Will Moschella, Al Mottur, Greta Joynes and Zach Pfister, all members of Brownstein Hyatt Farber Schreck’s Government Relations Department, were listed among the most influential lobbyists in D.C. by The Hill. In its 2025 Top Lobbyists list, the publication recognized the industry’s “savviest, most influential and well-connected advocates across Capitol Hill.”

Marc Lampkin is a highly respected advisor and veteran Republican lobbyist, bringing years of political, legislative and campaign experience to bear for his clients. His years on the Hill, campaign experience and extensive relationships with administration officials and staffers at policy think tanks, trade associations and the media have made him a trusted unofficial advisor for numerous members of Congress, cabinet officials and other leading Washington policymakers. Lampkin puts his political acumen to work navigating matters from both ends of Pennsylvania Avenue, from the White House to the Capitol and across the Senate to the House.

Will Moschella serves as co-chair of Brownstein’s Government Relations Department. He leverages his experience in the Justice Department and Congress to counsel clients on a range of matters, including antitrust, financial services, legal reform, intellectual property and criminal law. Moschella served at the Justice Department as principal associate deputy attorney general and as assistant attorney general in the Office of Legislative Affairs. In Congress, he served on the House Judiciary Committee as chief oversight counsel, chief legislative counsel and parliamentarian and was involved in numerous high-profile legislative efforts.

Al Mottur is a member of the firm’s Executive Committee and a senior Democratic strategist who solves the most complex and thorny political issues clients face in Washington, D.C. He connects organizations with leaders at the highest levels of Democratic politics and uses his legal and policy intellect to build consensus around solutions. As co-chair of the firm’s technology and telecommunication practice, Mottur engages federal policymakers as they develop legislation and regulations to address emerging technologies, data privacy, Big Tech, competition law and infrastructure.

Greta Joynes is co-chair of the firm’s technology and telecommunications practice. As federal policymakers consider industry-altering laws and regulations on data privacy, supply chain security, artificial intelligence, cybersecurity, energy, infrastructure and transportation, Joynes positions companies for success. Her technical understanding of clients’ businesses and political intuition on when and how to engage the government on their behalf has resulted in market-changing outcomes for small business coalitions, Series-A startups and Fortune 15 corporations. Joynes leverages her experience as a senior congressional aide to frame issues and pitch policy solutions in ways that resonate with key Republican decision-makers.

Zach Pfister has 20 years of experience in government, politics and advocacy and has built a large network of personal relationships with his former peers on Capitol Hill that extend across the House Democratic Caucus. Pfister’s reputation as a trusted intermediary and advocate, coupled with his substantive policy expertise and political instinct, have created a long record of success in shaping client outcomes in Congress.
