Operating through two business segments, the firm partners with management teams, entrepreneurs and business owners to facilitate management buyouts, majority and minority recapitalizations, growth financings, and acquisitions. It emphasizes relationship-building and tailored transactions, positioning itself as 'Main Street, not Wall Street' across diverse industry sectors and geographic regions.
