Dannell Landscaping and Lawn Care was built on a simple belief: people deserve a crew they can actually trust. One that shows up when they say they will, does clean work, and stands behind it. The owner is on every job — not as a talking point, but because that's the only way to make sure the work meets the standard we set for ourselves.
We work in the neighborhoods where our clients live, and that means something to us. Every yard we maintain and every landscape we build is a direct reflection of the pride we take in this business. We want you to pull into your driveway and feel good about what you see.
The Process
From first contact to a beautifully maintained yard — we make the process simple and stress-free.
Fill out the form, call, or text. We respond same day.
We come out to see the property in person, walk you through what we'd do, and give you a clear price upfront. No surprises.
We show up when we say we will, do the job right, and clean everything up. You don't even need to be home.

Very humble and easy going dude. He arrived early and got right to work. Will definitely call him for future lawn work.
Jalen is amazing. After speaking different landscapers, Jalen was hands down the best. Honest, direct, and professional. I’d strongly recommend asking for him.
