WE’VE BEEN SERVING THE LOWCOUNTRY FOR OVER 25 YEARS
Winthrop Tree Service is a fully insured and licensed company owned and operated by Arborist Gren Winthrop.
In 1994, at age 28, Gren and fellow certified Arborist Chris Gerards moved to Hilton Head, South Carolina to start new lives and a new company called Historic Tree Preservation Inc (HTP). With a keen focus on customer satisfaction and exceptional service, Gren and Chris grew HTP to five offices throughout SC, NC & GA. By 2003 Historic Tree Preservation had become synonymous with quality and was the fastest growing residential and commercial tree care company in the southeast.
In September of 2003 they accepted an offer of acquisition from renowned international giant Bartlett Tree Expert Company and in doing so they signed a five year non-compete agreement that expired in September 2008.
With renewed energy and a core group of employees, Gren was excited to be back in business as Winthrop Tree Service, LLC.
As we enter our 14th year in business, Winthrop Tree Service continues to grow with state-of-the-art equipment and nearly 25 employees. Our focus remains on quality work practices and exceptional service for our customers in the Charleston, South Carolina area.
