Gary Nussbaum began his career in building under the tutelage of his grandfather, Matthew Gregory, and father, Robert Nussbaum Sr., premier custom homebuilders in Joliet, Illinois from 1951 to 1975. Gary has gained valuable building expertise from years of working as a structural framer and finish carpenter. From 1975 to 1980, Gary continued to perfect his craft in structural framing and finish carpentry while working for his father Robert Nussbaum Sr. in Champaign, Illinois.


In 1980, Gary relocated to the Dallas/Fort Worth area, establishing a successful construction business that has achieved continued excellence in the field of premier remodeling, manufacturing of fine custom cabinetry and furniture, structural framing, finish carpentry, and general contracting.

Throughout the many years of his construction experience, Gary’s engineering mind has contributed the technical capability needed to execute the most challenging remodeling and new construction projects.
