"I was a skeptic that didn't think anyone really needed lawn care. I tried fertilizing myself a few times, but never got results. That was before GRASSMASTERS. After just one season, my lawn FINALLY looks as good as the other lawns. It's no coincidence that they also have Grassmasters signs in their yards six times a season!"

"I'm getting older, and even though I typically enjoy getting my spreader out for some fertilizer, I equally enjoy having an iced tea while Grassmasters does it. Plus, they are getting me results I never thought possible--and that's after 30+ years of doing it myself!"

"I'm the laziest yard guy there is, but once I got my new house landscaped, I figured I'd bite the bullet and have the yard done. I'd say it was 90 percent dandelions when Grassmasters first started. One season later, my lawn looks just as good as my lawn-obsessed friend down the block! Unreal!'
