Tasker Landscaping was established in 1978 by Gary Tasker upon his return home after 4 years of active duty with the US Air Force. The company began as a small one-man operation that provided grounds maintenance for private homes and a select few small businesses. In the early 1980's the business continued to grow and Gary's interests diversified to include landscape construction, excavation, home building, home renovation, and real estate development. During this period of diversification Gary also received an Associates Degree in Business from the New Hampshire Technical Institute in Concord.

In the late 1980's, as the economy changed, Gary decided to get back to basics and concentrated his efforts on commercial landscape maintenance and commercial and residential landscape construction. At that time, Joseph Supry joined the company as its landscape construction supervisor. To this day, Tasker Landscaping contines to grow and has received numerous awards for excellence for projects completed in Concord, Londonderry, Manchester and Amherst. The most recent being a Gold SAM Award for the landscape project completed at Concord Orthopaedics Professional Association in Concord as well as the national Concrete Pavement Award, given by Concrete Products Magazine, for brick work in Amherst.

Gary resides in Loudon with his wife Roxanne who is also his partner and office manager. Their daughter Jennifer also works for the company.
