"We have had many compliments on our flower beds. We were particularly grateful that you were able to utilize many of our existing plants; they are all doing very well after being transplanted into their new locations. Thank you for doing such a great job, you have a good eye!"

"Hennessey Landscaping was everything that we were looking for and more! Our project was complicated as we live on a lake and have wetlands. Mike took care of everything to make sure the proper permits and proper governing bodies had given their permission to do the project. It looks better than what we could have imagined! "

Without a doubt, I would hire and recommend Hennessey Landscape Services for any landscape needs.
