Our Story

Irrigation Northwest is a family owned business, operated by Terry and Heidi Dougherty since 1992.  In the early years Terry focused on mainly installing irrigation systems, for both residential and commercial projects.  After a few years he really enjoyed the creative side of landscaping so he decided to take on some landscaping projects.  He has found great satisfaction in seeing his clients happy with the design and implementation of his creativity. Matt Dougherty, their son has proven to be a very talented and creative hardscape designer and installer.
