Over a decade of excellent service and healthy lawns

Meet The Grass Authority

Established in 2010, The Grass Authority prides itself on growing and maintaining healthy lawns. The Grass Authority founder, Lu, was a lawn care aficionado and loved solving any yard problem that came his way. While he tragically passed in 2020, his knowledge, technical expertise, and love for the business lives on through the acquirement by Valley Green Inc. Owners, Jon and Michelle McDermeit, are committed to continue providing exceptional lawn care services to the Portland Metro area.

We get to the root of your lawn’s problem and offer customized and effective treatment for a healthy, thriving lawn. But don’t just take our word for it! See what our customers are saying:

“They provided fertilizer on a frequency that left our lawn looking great.”

— Jonathan B.

“My lawn has never looked better. They analyzed the problematic area, made a plan, and it is working!”

— Susie T.

  • My name is Jon McDermeit, the owner and operator of Valley Green Inc. When I founded Valley Green in 1990, my focus was to offer our customers a high quality landscape health care program at an affordable price. In 2002, my wife Michelle joined the company and has been managing the office for Valley Green ever since. She loves the opportunity to talk with customers and make sure they fully understand what technicians are trying to accomplish in your landscape.

    When Lu Vanderburg, the founder of The Grass Authority tragically passed away, Valley Green Inc, was honored to be given the opportunity to carry on Lu's service to his customers. Lu was a true professional and worked extremely hard to provide a premier service with unmatched results. We were very fortunate to have Austin Spencer, who had been the lead technician for the Grass Authority stay on and continue with us.

    As a lifetime resident of the Willamette Valley, I am very familiar with the lawn care needs of lawns in this area and look forward to sharing what I have learned.

  • Austin is our Lawn Care Technician; he’s been with the company for over four years. When he’s not working, he’s spending time with his wife, daughter, and two dogs, going for walks to the local park or cooking something delicious on the Traeger.
