David’s extensive strategic planning and corporate development experience makes him effective at leading and executing strategic planning, mergers and acquisitions and strategic partnerships. His expertise includes managing and executing acquisitions, advising on tax-efficient structuring and compliance and monitoring equity investments. He has also been responsible for day-to-day CFO functions, including debt structuring, bank compliance, financial reporting and treasury management.

Prior to joining Armanino, David served as a vice president of investments and CFO for a St. Louis-based family office, where he managed the controlling and non-controlling investments of the firm’s sole fund. David accelerated their newly adopted acquisition strategy, closing six acquisitions over eight years and diversifying revenue streams across multiple industries, sectors, product lines, end users and service types. He also formalized the M&A process, restructured legal entities, decentralized day-to-day operational management of the portfolio companies and completed a management buyout of existing shareholders.
