About G&M

A Company Built on A Positive Attitude

Our Story

After years of working for other landscapers and contractors, brother-sister duo, Garrett and Marlena knew they wanted to form their own company. Previous companies had divided teams with negative attitudes toward co-workers, projects, and customers. They wanted to work within a different culture.

In 2017, Garrett and Marlena founded G&M Outdoor Services with the goal of creating a positive and uplifting environment for their employees and customers. Thanks to their community and customers, their goal for a positive culture was rewarded. G&M has become one of the fastest-growing and most-trusted residential and commercial excavation teams.

Proudly operating as G&M Companies in 2026, we look forward to learning your story and putting a smile on your face!

Our Team

Garrett Williams

Founder / Sales & Business Development

Hi, I’m Garrett! I am a co-owner of G&M and oversee our sales and business development. I love coming into work everyday and seeing a smile on everyone’s face. My passion for landscaping started from a young age. When I was 11 years old, I started operating heavy equipment and have loved it ever since. When not in the office or operating equipment, you can find me starting a conversation with a potential customer or new employee or filming my latest YouTube video.
