HPSI is one of the longest surviving organizations of the Chicago Hellenic Community. Since its inception, HPSI has served as a meeting ground for professional individuals of Hellenic descent
. HPSI hosts many events throughout the year, including: lectures on cultural, historic and business topics, social events, including the annual Membership and Christmas parties, as well as philanthropic events. Over the years, HPSI has raised money to support many organizations and causes such as: Hellenic Foundation, Hellenic Museum and Hepatitis-C Research.
