Our Advisory Board

Ken Wanko | ESOP Strategies

Board expert. Investor. Operator. Financier.

Ken has, for the last 20 years, advocated equality and progress through the use of employee ownership as a positive economic construct.

Ken’s journey as an employee ownership zealot began at the investment banking firm, Houlihan Lokey. While there, Ken was a founding member of Houlihan’s ESOP Corporate Finance Group, providing expert-level guidance to companies, their boards and employee groups that wished to become employee-owned.

After his tenure at Houlihan, Ken spent 14 years at the 100% ESOP-owned investment company, Alliance Holdings. At Alliance, Ken was first Director of Acquisitions and then Chairman and CEO - Alliance was one of the largest ESOP-owned in the U.S., with more than 15,000 participants. Alliance’s unique, internally diversified approach to employee ownership has since been copied by several ESOP companies.

Currently, as Managing Director of SES ESOP Strategies, Ken advises companies, owners and other stakeholders on various corporate transactions, focusing on ESOP ownership transitions, M&A advisory and private capital raises. To accomplish this, Ken brings his breadth of experience as a former board member, business leader, and investor of many ESOP-owned businesses.

Ken’s professional career began as an engineer for Lockheed, where he designed software to manage the orbital analysis of the US Government’s surveillance satellite system.

Ken holds an MBA from Duke University, the Fuqua School of Business, and a B.S. from The University of Michigan, B.S., Aerospace Engineering.
