Customer Reviews

Philip DeFranco

I have been using the services of GreenKnights landscaping since they took over for Killeen Bros for both weekly lawn service, seasonal bed maintenance &yard cleanup and for some bigger landscape and design projects ( came up with a solution to make a stone walk way with sitting area through an area with poor drainage) They are always prompt, professional and masterful at what they do. Lots of props to Dom for being a great owner who stands behind his work, easy to work with, personal and ensures things get taken care of for his clients!

Rita Masterson

GreenKnight is very dependable and show up timely for lawn service. They listen to me when I make any requests. They are quick and efficient and my yard and lawn look well groomed. Dom is also always personable and easy to deal with as are his employees. I would highly recommend them!!

Sherry Gangloff

Greenknight Landscaping is very professional and prompt! I have used them for my landscaping needs and for snow removal for over 9 years! They have always plowed the driveway early morning so we are able to go to work on time. Never have they been late! They have exceeded my expectations in every way!

Ryan LaCotte

I have had a variety of services from Green Knight with great satisfaction over the past 10 years. Spring cleanup and mulch – outstanding. Always on time for our lawn service weekly and snow plowing is the best I have had in 25 years of home ownership.

Marcia Hunt

GreenKnight has been cutting my lawn for more than 5 years. They are like clockwork arriving on Tuesday to cut & edge my lawn. It’s always perfect. They now do my Spring and Fall cleanup too. Delightful to work with DOM & team.
