Owner of Mr. Greenthumb LLC Colorado | President

"There’s a great sense of satisfaction working with Clients to design and install their new outdoor space. We take great pride in providing our Clients with quality work and an exceptional experience.”


Devin started Mr. Greenthumb in 2006 with a 1954 Chevy and a couple of lawn mowers. To this day, we still work for many of our original Clients. Mr Greenthumb grew into a family business when Devin's wife, Annie, left the dental field to work side by side managing business operations.

I love getting to know our Clients and be part of making their properties beautiful. Working behind the scenes is just as rewarding as creating the new landscape on site. Talking with the Client from day one, being part of the vision and seeing it come to fruition is wonderful!
