The Early Years

My name is Brett Kallias and I want to be your landscaping contractor, providing Accelerated Green Works, Inc. as your personal ground maintenance firm.


I was raised in Minot, North Dakota, where my grandfather owned and operated a business for 35 years. Watching my both my father and grandfather work in a customer-service business helped to develop my interest in establishing a community service business of my own.  Over the years, I have found that there is no greater pleasure than seeing the satisfaction of my customers for a job done well.


My career began when I worked for “Olson’s Landscaping” in Minot, ND, while I was in high school. At Olson’s, I had a teacher who mentored me in all aspects of the landscaping/lawn care company.  In 1998, I decided to open up my own mowing and landscaping business in the Minot area. This successful endeavor continued for four years while I attended college until I graduated with a degree in Construction Engineering from North Dakota State University in 2002.


After graduation from college, I went to work for the ND Department of Transportation (ND DOT) in the Devils Lake District where I continued to work in the transportation industry for 4 years.  The ND DOT provided me with new exposure and job experience while I worked on constructing new bridges and roads across North Dakota.  Even as invigorating as the jobs were, I found there was something missing.  I remembered the pleasure I received from working with people and I missed that interaction.  My mowing and landscaping days were still near and dear to my heart.  It was those memories that drove me back into the business in 2006.


At Accelerated Green Works, Inc., we handle commercial and residential spring and fall clean-up along with weekly mowing, monthly fertilization and weed control, edging, shrub trimming, aeration, sod installation, hydro-turfing, rock installation, landscape block/paver installation, concrete installation, flood cleanup and renovation, snow removal and all your other yard needs.  My father was very particular and that attention to detail seemed to rub-off on me, resulting in a final product much different from most other lawn care specialists.  We do the job “right the first time” and we make sure you are completely satisfied with the finished product before we leave the job site.  You can count on that.  Customer satisfaction with our professional work is our number one priority as we continue to serve the West Fargo, Fargo and Moorhead areas (as well as our recent expansion to the lakes region and western North Dakota).


To be sure we are always on top of new innovations in the landscaping field, we continue to attend classes each winter and early spring to learn about new products available as well as installation techniques and other tips.  I am confident that there is nothing my crew cannot handle.  Since graduation from North Dakota State, I look to them for students in the same program and other engineering fields and hand select my workers to ensure that my clients are always (1) safe, (2) comfortable and (3) happy with their project from start to finish.


Thank you for the opportunity to serve and get to know you!
