Our Boards include local government administrators and elected officials who are accountable to you.

Lone Star Investment Pool is overseen by the Board of Trustees, which is comprised of active members of the Pool and elected by participants for three-year terms. Their work is guided by the Advisory Board, which also includes member representatives as well as an independent advisor.

Each quarter, Board members get together to review the Pool's operations, fine-tune investment policy, analyze audits, or approve contractor agreements. Pool members can rest assured that this dedicated Board — not a distant agency or corporation — is taking a careful and considered approach to every investment decision.

Our Advisory Board is made up of participants from many forms of local government. They meet annually to provide information, input and feedback about members’ needs and Lone Star services. The Advisory Board is also tasked with reviewing and evaluating the performance of the First Public leadership team.

RSM US LLP, a full-service accounting firm located in Austin, conducts an annual audit of the Pool's financial statements.
