HIGHLIGHTING the best of the best

SERVING The Greater Olney MD Area


PH: 301.450.SUST (7878)

The First in Maryland!

Green MowCo has expanded its service in Montgomery acquiring another local, all-electric mowing business, and has rebranded as Sust.

Sust is the first AGZA Certified Service Pro in the state of Maryland.  Sust owner William Zimmerman is not only running an ultra low impact all electric landscape maintenance business, but is contributing to the outreach and education of our changing industry.  William attended an AGZA workshop co-sponsored by NALP (National Association of Landscape Professionals) and Montgomery County.  He was not only an attendee but was a featured guest speaker in front of an audience of nearly 100 grounds maintenance operators.  William was able to speak to the locality of operations in the Montgomery County area and how his experience has been so far.  AGZA would like to thank Sust for their participation and being a true example of responsible change.  

With over a decades worth of industry experience, Sust has excellent customer reviews and prides itself on providing a reliable professional service to go along with their dedicated low impact approach to the business. AGZA encourages folks in Montgomery County to contact Sust if interested in quieter, lower impact land care and maintenance operations.  

Currently servicing these zip codes:  20852, 20817, 20816, 20815, 20814, 20853, 20833, 20832
