Award-winning landscape architects David Retzsch, RLA, and Shane Friese, RLA, have joined Freese and Nichols’ urban design team. David and Shane, who are based in Dallas, will strengthen our team’s capabilities in urban design, parks and trails, streetscapes, downtown revitalization and other services. We now have eight landscape architects serving cities and counties throughout Texas, Oklahoma, North Carolina and Georgia.

“Shane and David’s combined experience in landscape architecture is a tremendous asset to Freese and Nichols,” said Brian Coltharp, P.E., President and CEO of Freese and Nichols. “Their expertise and insight will help our growing team provide innovative solutions in parks and recreation, transportation enhancements and urban design.”

Throughout his 35-year career in Dallas-Fort Worth, David has gained diverse experience in architecture, engineering and landscape architecture contexts. He has worked extensively in transportation-related urban design, as well as urban parks, higher education and commercial site development. Having served in numerous leadership positions, he is adept at design collaboration, consensus building and delivery of multidisciplinary projects.

David earned his bachelor’s degree in landscape architecture from the University of Illinois at Urbana-Champaign. Among other recognitions, he is a former Trustee, a Past President and a Planning and Design Awards recipient of the Texas Chapter of the American Society of Landscape Architects.


Shane, who received the 2015 National Award of Excellence from the American Society of Landscape Architects, has experience in all facets of landscape projects – from complex analysis to design and management. His career has spanned a wide range from mixed-use to parks to residential developments, and he has handled program development, space planning, design and construction administration.
