About Us


Designing gardens for people is a business we love.

Since graduating Cal-Poly San Luis Obispo, Karen has been developing her award-winning practice for over 35 years, working on a variety of important projects including Bonfante Gardens, the Santa Cruz Boardwalk, and numerous high-profile residential landscapes. Karen continues her practice from beautiful Gilroy, California, and serves clients in and around the LA and Bay Areas.

Karen founded Aitken & Associates as a Landscape Architecture firm serving the unique needs of Northern California.  Our reputation is based, in part, upon listening and responding to our clients’ unique needs, and in creating delightful environments tailored to their wishes and desires.  We take pride in creating thoughtful, innovative and environmentally conscious landscapes, which will serve you for years to come.

A project we are very proud of is the Landscape Master plan and plant selection for the world-famous Bonfante Gardens Horticultural Theme Park located in Gilroy, California. We have been most gratified by the reaction from the public, especially from the children who use this park.

With a commitment to community service, Karen has long been active as a member of both the Gilroy Rotary Club and Gilroy Assistance League. Additionally, she has been a member of A.S.L.A., the American Society of Landscape Architects, for over 30 years.

Aitken Associates has been honored with the 2001 Best Small Business of the Year,  by the Gilroy Chamber of Commerce for success in business and commitment to community service.

Recently, the American Horticulture Society Garden School at the Franklin Park Conservatory in Columbus, Ohio honored Karen as their featured speaker and guest lecturer.

We are so proud of our work. If you are interested, take a look at our portfolio! Or if you want to move forward on your project now you can contact us as well.
