1975:

The Senior Adult Activity Center of Harleysville Area and The North Penn Senior Adult Activity Center were each incorporated in 1975. Each Center functioned as its own 501(c)3 non-profit until the merger almost 40 years later.

1981:

The Harleysville Senior Center first operated in Alumni Hall, a building belonging to Lower Salford Township. In 1981, the Township purchased and remodeled a former factory (coincidentally named SPARK!) which has been the Center’s home in Harleysville ever since.

1983:

The PEAK Center was located at 315 West Main Street in Lansdale, from 1983 - 2013.

2013:

Encore Experiences merged with The PEAK Center in 2013, creating Greater Harleysville and North Penn Senior Services as the umbrella organization which oversaw the operations of both facilities. At this time the PEAK center moved to a temporary location at the Advanced Living Communities Campus known as Schwenckfeld Manor, where it remained during the construction of the North Penn Commons.

2016:

The Peak Center found its current home within the North Penn Commons upon the completion of the construction of this facility in October of 2016.

2025:

In June of 2025, Greater Harleysville and North Penn Senior Services officially rebranded as SPARK Senior Centers of Montgomery County. Encore Experiences is now known as SPARK Senior Center of Harleysville, and The PEAK Center is now known as SPARK Senior Center of Lansdale. This change promotes unity between our two centers and sets us up for a bright future of “Sparking Connections and Enriching Lives” for local seniors.
