Andrew Williams is a Vice President at Cornerstone Business Services, where he advises business owners through mergers, acquisitions, and ownership transitions. With more than 18 years of M&A experience, Andrew works closely with founders and family-owned businesses to prepare for sale, execute competitive marketing processes, and successfully navigate the complexities of a business transition.
Prior to joining Cornerstone, Andrew held senior investment banking roles with several middle-market advisory firms, where he advised business owners through sell-side M&A transactions across a variety of industries. Before becoming an investment banker, Andrew was the co-founder and Chief Operating Officer of a family-owned business that he helped launch, grow and ultimately exited. That firsthand experience as both an owner and advisor gives him a unique perspective on the financial, operational, and personal considerations involved in selling a business.
Andrew is a Certified Exit Planning Advisor (CEPA), a Certified Merger & Acquisition Advisor (CM&AA), and previously served as an EOS Implementer, helping leadership teams strengthen accountability, execution, and long-term business performance. He also holds FINRA Series 82, 79, and 63 licenses and is the author of Second Wave Life and Don’t Leave Life on the Table, where he shares insights on preparing business owners for life before and after a successful exit. Andrew earned a Bachelor of Engineering from Michigan State University.
