## About

The Oakland County Treasurer’s Office was established to manage public funds for Oakland County, Michigan. Robert Wittenberg holds the dual role of Treasurer and Chief Investment Officer. The office allocates across public equities managed by Graystone Consulting and Harding Loevner, fixed income through ASB Capital Management and Cumberland Advisors, and private equity commitments to Hamilton Lane, Capital Dynamics, Portfolio Advisors, and Marathon Asset Management. It also oversees a Delinquent Tax Revolving Fund of $200 million and a Local Government Investment Pool of $1 billion. Geographic focus remains within the United States, primarily Michigan. The office employs no disclosed headcount beyond key staff. It maintains the Oakland County Land Bank Authority, which holds over 400 tax-foreclosed properties.
