Our Team

Without question, GSI’s greatest asset is our team of accomplished professionals. We draw on decades of experience in the philanthropic sector—not only as consultants but as front-line, hands-on fundraisers and development executives.

When you work with GSI, you gain access to our entire firm of experienced consultants and benefit from close, regular interaction with the most senior members of our team.

 We wanted an organization that worked collaboratively and seamlessly with clients, teaming with them to raise donor sights, to think big and not be satisfied with current standards. More than 30 years later, we are proud to say we’ve never wavered from that ideal, reinforcing it daily with great success. We’ve managed it with a team of like-minded staff professionals who bring extraordinary skills and dogged pursuit of excellence.
