This historic farm was owned and operated by the Grossmann Family from 1895 to 2007. In recent years, uncertainty over what would become of the village landmark troubled many of Malverne's residents, but in late 2009, Thomas Suozzi, then current Nassau County Executive, announced that the County intended to purchase the property and preserve its farming roots. Soon after taking office, Suozzi's replacement, Ed Mangano finalized the deal on Feb. 8. 2010.
Nassau County purchased the five-acre farmland for $6,538,233. The Grossmann family retained 0.2 acres of the property, which includes the original homestead, the white house that faces the intersection at Hempstead Avenue and Ocean Avenue. The village of Malverne secured slightly less than a half acre.
The County acquisition was made possible through the 2006 Environmental Bond Act, a $150 million dollar environmental program that has enabled Nassau County to purchase and protect open spaces and renovate parks. After putting out a call for proposals in the summer of 2009, the County selected Nassau Land Trust to operate the farm and a contract between the two parties was finalized in late 2010.
The Nassau Land Trust hired a farmer, Bill Walsh, established committees and recruited local volunteers and opened the farm again on April 30, 2011.
On July 1, 2011 the trust announced that in cooperation with the Grossmann family, they changed the name of the farm to Crossroads Farm at Grossmann's to reflect both its roots and new beginning.
