About Us

Tierra Group is . . .

a female-owned  Landscape Architectural firm  with more than 25 years experience in residential  and commercial  design, as well as other municipal-based projects, including  parks, streetscapes, master plans, and military facilities. 

Tierra Group is owned by Lisa Pierce, a  licensed  California Landscape Architect and a 1984 graduate of Cal Poly University, Pomona  with a BS degree in Landscape Architecture.  Lisa  began her career working for large,  award-winning Landscape  Architecture/Planning and Engineering firms that gave  her a broad  knowledge of the industry. Following several years of experience, Lisa  developed a greater interest  in residential design, especially custom  residential projects, where she began  enjoying the challenge and  creativity of unique properties and the personal relationships with her clients. 

Lisa began her company, Tierra Group, in 1990  and has since developed a  strong client base throughout Southern California. She has mentored  young students interested in the profession, provided expert witness testimony for various projects, and is  currently a reviewing Landscape  Architect for a custom residential Homeowner Association community in  the area. 

Tierra Group is . . .


a full service design firm,  capable of managing a project from the initial site  meeting to final  completion. Throughout  the design process, the client’s specific needs and budgetary constraints are respected. Lisa’s attention to detail and keen ability  to successfully listen and implement every idea, wish,  and dream of her clients  is what distinguishes her work. It is  her  thoughtful balance of integrating site issues, building styles, and  function, as well as aesthetic quality, which guarantees that every project will be a successful one.

Tierra Group is  experienced in a wide variety of design styles, including formal, traditional, tropical, contemporary, country cottage, and several other region-specific styles such as Italian, Mediterranean, Asian, and English. Lisa’s expertise also extends to Xeriscape design, which incorporates California native and drought tolerant plant species into a  more natural landscape that lowers maintenance costs and water consumption.
