Leadership

We tend to grow our own: Most of our top executives have been with the firm for decades and have deep ties with our clients and the professional community. Our leaders are employee-shareholders of the firm and no shareholder holds more than 6% of outstanding shares. To ensure an infusion of diverse experience and fresh thinking, we also hire many mid-career professionals, and seek and cultivate young candidates from across the globe.

Our commitment spans a wide range of pro bono and philanthropic work -- from our founding of the ACE Mentor program, to supporting a local food bank, the STEM education of young girls, or sharing our expertise with disadvantaged communities.
