Knazs, Ross

Ross Knazs is the co-owner and lead landscape architect for L&L Landscaping in Alamo, California. He began his career as a designer and project manager for a landscape architecture and planning firm in southern California, after serving his country honorably for seven years on active duty in the United States Navy. While at this design firm, Ross managed and collaborated with team members on over 100 projects including sports complexes, urban and dog parks, private residences, apartments and condos, commercial properties, streetscapes, medians, campus master plans, golf courses, wetland mitigation, and rehabilitation projects.

Ross’s career as a licensed landscape architect has further progressed as the lead landscape architect and project manager at L&L Landscaping. His finely honed sense of detail and understanding of the land has taught him the importance of designing spaces that encourage, rather than inhibit, the community. His experience working for both landscape architecture and planning firms and land development companies on large master planned communities provides him a distinct perspective to carry landscape design from concept through construction while balancing quality of design, materials, and budget with client expectations.

Ross holds a Bachelor of Landscape Architecture from LSU. Additionally, he is a licensed landscape architect in the state of California.
