  • Phase One Landscapes was a delight to work with, and I am a very picky consumer. From the design to the execution, they were professional in every way. The on-site crew was hard working, quiet, and respectful of my needs. The job came out better and more beautiful than I had imagined. I highly recommend this company for their knowledge, work ethic and creativity!

  • Let me just say how fabulous your design is! I knew from experience that we would be happy after the project was done, but I am absolutely delighted with the way this turned out. The new finishes and retaining wall not only made an ugly porch beautiful, but it balanced out the entire look of the front of the house. Neighbors walk by and take notice - sometimes they just stand out there for minutes at a time just to look and enjoy the changes! You're a genius - and we're grateful!

  • Just a note of thanks to you for a wonderful job on our back yard. Michael and I have been happy from start to finish. Our Designer was terrific and Modesto and his crew were exceptional. We would recommend your company to anyone.
