From Our Clients

This is a 5-star company. Excellent in every way. I reached out to 7 companies before John Mennonna .  None of the others bothered to contact me. John is punctual, and dependable a real gem to work with. I appreciated the job he did.

 Hired on the spot. Amazingly the job was done the same day with great care and performance. Cleaned all the beds of weeds, prepped for mulch installation, installed the mulch, edged the grass, and cleaned everything up. This is the start of a beautiful relationship. I can’t wait for my list of improvements and the weekly lawn service to be started. Five stars. I couldn’t be happier!
