Our Team

With extensive experience and deep relationships in the Capitol, our team is ready to successfully pursue Clients' policy objectives. 




With over 30 years experience in the Missouri Capitol, David has become a trusted policy resource for members of the executive and legislative branches.  His well-earned reputation for issue-area expertise and legislative strategy is built on two decades of successes in the policy and appropriations arenas.  With deep relationships and unparalleled knowledge of clients’ issues, David has a proven track record of achieving policy objectives. 

His work in the Capitol began in 1992 as Government Affairs Director for the Jewish Federation of St. Louis.   Since 1994, David has represented a wide array of clients and issues, ranging from education to utilities.  With this breadth of experience, David understands how to move, oppose, and negotiate complicated legislation.  In addition to leading legislative and appropriations efforts as the sole lobbyist, David has developed close working relationships with his lobbying colleagues, allowing him to seamlessly work in coalitions.  This ensures clients have access to his support, but also other allied groups that may see value in a particular area. 

David has developed expertise in human service policy and the appropriations process.  This places him in a unique position to protect existing budget items, explore funding mechanisms for new initiatives, and strategically maximize available revenue. 

David’s commitment to hard work and accountability extends beyond the legislative session.  After bills pass, he works closely with the Executive Branch on gubernatorial approval as well as department implementation and rule making.  During the Legislature’s off-session, you’ll find him in Jefferson City or Legislators’ home districts, building relationships, gathering information on emerging issues, and consulting with clients on responses to opportunities and challenges.

He earned a degree in Economics and a Master's in Public Administration and Public Policy from the University of Florida at Gainesville.  David lives in Columbia with his wife, Beth, and their younger son. Beth holds a PhD in Education from the University of Missouri.  She teaches Gifted Education at Jefferson Middle School and directs the Gifted Education Program for the Columbia Public School District.  Their oldest son, Jacob, graduated with a degree in Astrophysics from the University of Alabama and is now earning his MBA. David and Beth's younger son, Noah, is a student at Rock Bridge High School. He has earned a top position in the Missouri Valley Tennis Rankings. David enjoys spending time with his family and can often be found on weekends at his son’s tennis tournaments.

He also works as managing partner of the Grote Group L.L.C., a law firm specializing in campaign finance, election law compliance, and government relations.  In addition to his practice at Grote & Associates and the Grote Group, Mike began working with the WPG lobbying team in 2018.  He works alongside David and Jessica in the Capitol to support clients' legislative priorities in the Capitol.
