Meet the team

St. Louis Design Alliance was incorporated in 1977 and has been under present ownership since 1982. The composition of our experienced professional staff is diverse and covers both architecture and interior design.

The size and depth of our staff allows us to maintain production schedules even on substantial projects but without the cumbersome management layers typically associated with larger firms.
