The Grounds Professionals Difference

Our talented team of designers, landscapers and contractors all work hard to provide you with high quality service and gorgeous landscapes. We offer a broad range of options to incorporate into any landscape design. In addition to landscape installation and plantings, we also design and build custom outdoor landscape features.


  • Redesigned Outdoor Living Space
  • Decks
  • Fences
  • Firepits
  • Pathways
  • Patios
  • Walls
  • Water Features

I have always felt that if you are planning to spend money on your outdoor living space, it is a good time to review how you currently use it & how you want to use it, what you love about it & what challenges you have. That way you can get the most for every dollar spent.
