About Us

Studio-based Landscape Architecture firm committed to personal client service and thoughtful design.

SGA Group is a Service-Disabled Veteran-Owned Small Business (SDVOSB), formed in January of 2011. We are a corporation under the laws of the State of Minnesota and certified as a Small Business Enterprise (SBE).

We approach each project with the idea that the natural environment is the basic foundation for developing memorable spaces that people use and enjoy. SGA assists clients through all phases of project development, from initial concept and construction documents to landscape establishment and next use scenarios. We incorporate environmental, cultural, and economic aspects into every step of our design process to produce solutions that are unique to each client and each location.

Going forward, we will utilize “blue-green” natural infrastructure systems as a method of addressing the wide variety of increasingly complex ecosystem issues. SGA will integrate planning, design, writing, and research to achieve the best possible outcomes with the least environmental cost.
