GSI EXECUTIVE TEAM


Peter W. Ghiorsi, MBA, FAHP and Dan Sorrenti have devoted their entire professional careers to the field of philanthropy. In 1989, after many years of service to a major teaching medical center, they combined their professional ambitions and skills to form Ghiorsi & Sorrenti, Inc. Together, and with a team of talented executives who are experts in all aspects of philanthropic consulting, they have built a firm that has experienced steady growth as it has partnered with hundreds of non-profits throughout the United States in raising billions of dollars in philanthropic support. They are committed to being actively involved in serving all of the firm`s clients. This is as true today as it was when GSI opened its doors in 1989.Click on a name to learn more about that GSI team member.
