"Peter Anthony Landscaping has done an amazing job on my yard! We spend a lot of time with family & friends now that we have a yard that everyone enjoys!" Earl Garrison


"All of us are amazed by the quality and the overall beauty of your work. It truly exceeded our expectations and it was a great pleasure dealing with an individual that did exactly what he proposed." M. Sanator


"I recently bought a house and the landscape was in ruins. I knew it would be a large job so I met with many candidates. When I first met with Pete, I immediately noticed a difference between him and any other landscaper. He was clearly sophisticated, experienced, and creative. He listened carefully to everything I wanted, and quickly came back with a 3D computer image that blew us all away. His extremely creative design and competitive price made all the other landscapers pale in comparison." Jon Fuss
