Tompkins Excavating, an award-winning large-scale excavation company with a longstanding commitment to Westchester and Putnam counties, is celebrating its 30th anniversary.

The woman-owned, family-operated company has developed a reputation for delivering a diversified portfolio of detail-oriented, quality work and maintaining a strong commitment to giving back to the community.

Company founder Mark Tompkins started cutting lawns during his high school years and his business eventually evolved into a full-service excavating company. By 1986, he incorporated the company as Tompkins Landscaping Corporation and when his wife, Stacey, joined the business in 1990, she helped shift the company’s focus toward landscape construction and excavation work.

The company’s turning point arrived in the mid-1990s, when Tompkins landed its largest to date commercial excavation project: site work for the BJ’s Wholesale Club in Yorktown Heights.

Some recent work includes a five-lot subdivision in Cortlandt Manor, infrastructure work for a condominium complex in Brewster and its largest commercial contract to date, Main Street Commons in Peekskill. Anchor tenants at the project will include an Auto Zone and Family Dollar stores.

This year, Westfair Communications bestowed Tompkins Excavating with its annual Family-Owned Business Award and the Putnam Valley Education Foundation honored Stacey and Mark the firm for their community service contributions over the past 15 years. In 2015, Tompkins Excavating received the Habitat for Humanity Cornerstone Award for volunteer work performed on a Habitat home and in 2013, the Putnam County Chambers of Commerce honored her with a Mature Trailblazer Success award.

Over the years, Tompkins Excavating has helped support various charities and organizations, including Putnam Valley Central School District, Armonk Outdoor Art Show, Jan Peek House Shelter for the Homeless, Community Cares of Mahopac, Support Connection, Community Center of Northern Westchester, Project Yellow Light and the Lustgarden Foundation. –
