About Columbine Landscape, Inc.

We are a licensed C-27 landscape contractor. Owners Mark and Nicolette Sterk first opened our door for business in the fall of 1986 as a commercial landscape installation and maintenance company, but found our niche and enjoyment of the industry in estate and residential landscape maintenance, improvements, construction and renovation, where working directly with clients and being involved creatively proved to be most satisfying for us.
