Our Story
Built by a Family That Loves the Outdoors
GROUNDWORK CO. was founded in 2011 by Marcus and Julia Harmon, two landscape architects who left corporate design firms to build something of their own — a company that treated every client's yard like it was their own backyard. Starting with just a truck and a trailer, they've grown into a 24-person team serving over 300 active clients across Orange County. What hasn't changed: the personal attention, the honest pricing, and the obsession with doing the job right the first time.
"We don't just maintain yards. We help families fall in love with their outdoor space."

"Groundwork completely transformed our backyard from a dead grass wasteland into something we actually use every day. The design process was collaborative, the crew was clean and professional, and the result exceeded every expectation. Highly, highly recommend."

"We've had three landscapers over the years. None of them came close to Groundwork. They remembered our preferences, showed up when they said they would, and our yard has never looked better. We're on the monthly maintenance plan and it's been flawless."
Tom & Renee B.
Newport Beach · Google Review
"I manage several commercial properties in Irvine and Groundwork handles all of them. Reliable, professional, responsive, and their crews are careful with the properties. They've saved me from two HOA violations just by staying on top of things I would've missed. That's value."
