G&M History: 

After years of working for other landscapers and contractors in the area, It made sense to merge the skills set that brother-sister duo Garrett & Marlena Williams had, in June 2017 G&M Outdoor Services, LLC was formed. G&M is recognized as a growing team with passion for technology, education, and building strong lasting relationships with our clients, employees, and vendors. 

G&M has become one of the industry's fastest growing and most trusted residential and commercial outdoor services team, proudly serving the greater Monticello / Big Lake area. We offer a comprehensive selection of outdoor services: landscaping, excavating and snow removal. From planning and design, to a mature and thriving landscape into the ground. 

We look forward to continuing to serve our valued clients, employees, vendors, and community for years to come.
