Jeff Ambrosia
Owner and Principal

jeff@yamasaki-la.com

With decades of experience in multi-disciplinary collaboration, design development, and creative problem solving, Jeff brings a vast well of knowledge to Yamasaki Landscape Architecture.  He has gained fundamental "hands-on" experience through both in landscape architecture design and construction. His experience has fostered an acute attention to detail and a deep understanding of all phases of a project from conceptual design through construction. 

When Jeff's not busy with work and community projects, he enjoys camping and boating with his family. Look for him at the local early-morning masters swim, one of our local golf courses, or out on the trail with his dog.
