About HICKSVILLE GREGORY MUSEUM

Hicksville Gregory Museum is a community-based natural history and earth-science museum housed in the historic Heitz Place Courthouse in Hicksville, New York. Founded in the mid-1960s and named for William Gregory, the museum preserves collections of fossils, minerals, lepidoptery and local artifacts and emphasizes hands-on, classroom-aligned programming for school groups.

The museum operates as a 501(c)(3) public charity (EIN 11-2124537) and partners closely with Hicksville Public Schools to provide tours, outreach, and community events. In the past 2–3 years the museum has continued regular school programming, hosted community events, and maintained fiscal filings and modest operating revenue to support educational activity and building maintenance.

Notable achievements

Established multi-decade educational presence

Founded in the mid-1960s, the Gregory Museum has provided more than five decades of earth-science and local-history education to Hicksville and Long Island schoolchildren and residents.

Sustained student and public reach

In recent reporting years the museum reports serving several thousand visitors annually — including roughly 3,500–4,000 students through organized school tours and outreach programs and approximately 6,000 general visitors — supporting hands-on learning outside the classroom.

Facility improvements and active programming

The museum has invested in building systems and programming continuity (for example an HVAC upgrade in recent years) and continued to host community-oriented events and special programs, demonstrating operational upkeep and ongoing public engagement.
