Pillar Icon



True Partners was founded during turbulent times. Since 2005 our leadership team, led by Cary McMillan (2005 – 2020) and now Tim Costello, has successfully navigated economic, legislative and generational change resulting in consistent, high-percentage growth for the firm.

In 2015 firm ownership was transitioned from a Chicago-based private equity firm to True Partners managing directors. This highly talented group, many of whom enjoyed extremely successful careers in large public accounting firms, protect and help evolve the vision of our founders; to build a nationally recognized tax and business advisory firm dedicated to collaborative client service, innovation and providing rewarding career opportunities for our people.
