About Us

Green Horizon Landscaping, Inc. has been shaping landscape dreams in the Conejo Valley since 1987.  We take pride in providing for every detail "From Creation to Completion".

Owner and President, Glenn Thompson, was raised on a family owned nursery in Simi Valley.  He launched his own gardening and maintenance company in 1984.  Quickly developing an aptitude for seeing a yard and having the vision for it's transformation, he moved into the "creation" part of the business in 1987.

The lion's share of our business comes from repeat business and client referrals.  Glenn was raised on the principle that you can do things quick and shoddy, or you can do it "right".  It has always been Glenn's passion to explain the options thoroughly to help his clients understand the value of doing it "right" the first time.  "Right" is not always the cheapest, but is always most cost effective, in the long run.

Glenn has been a member of the California Landscape Contractors Association since early 1990.  A multi-year receipient of awards for "Landscape Design and Build" projects that range from newly constructed homes to partial or complete renovation.
