GreenTech was founded in 2019 by Shawn Rathjens and Jenel Russell. Our motivation in creating this company was the growing need for professional lawn and tree care services in the East end of Long Island. Not only was there a severe need for such services, but there was also a serious lack of providers who offered sustainable solutions.

As professional landscapers, we recognize the need to safeguard the environment for the future. As such, we set out on our mission. That is to not only deliver excellent landscaping solutions, but to also protect and nurture the environment while we’re at it.

We also wished to prioritize client satisfaction above all else, so we made our programs adjustable to each person’s needs. Everyone on our team was handpicked with these objectives in mind. So, our clients can rest assured knowing they have a team of highly skilled professionals working for them.
