About Us


Sierra Landscape began as a one man operation providing residential and commercial landscape maintenance under the name of Sierra Gardening Service. Started by Richard Watchler in 1983, Sierra Gardening Service provided quality maintenance throughout the San Gabriel Valley.

Finding the need to further his knowledge of the various aspects of landscaping, Richard returned to college and earned a Bachelor of Science degree in Ornamental Horticulture from California Polytechnic University at Pomona in 1987.

Fresh out of school, Richard obtained his California State Contractor’s License in Landscaping. (C-27 # 514938) As a result, the business name changed to Sierra Landscape Co. and began providing quality residential and commercial landscape installations as well as continuing to provide landscape maintenance services.

As the business grew and additional employees were added, the company was incorporated and is now known as Sierra Landscape Development Inc.

We pride ourselves on providing our clients with the utmost in customer service from simple irrigation repair work to full fledged landscape development of large institutional, commercial, residential and estate properties.
