After completing her interior design degree at Brooks College of Design in Long Beach California, Beth worked as an intern with MVA Architects, where she focused on commercial tenant improvement projects. Challenged to advance in the field of design, she returned to school to complete her Bachelor of Architecture at the University of Oklahoma, where she graduated at the top of her class in 2003.

Beth spent six years with Miles Associates as an architectural intern and project coordinator where she gained valuable experience. In 2006, she relocated to southern Oklahoma to manage her former husband’s construction company while he was deployed overseas. In 2009, Beth became a Registered Architect and established Southern Design Group, LLC (now referred to as SDG Architects) in Ardmore, Oklahoma to return to her commercial design background.

In 2015, Governor Mary Fallin appointed Beth to the Board of Governors of the Licensed Architects, Landscape Architects and Registered Interior Designers of Oklahoma. She also serves on the University of Oklahoma Division of Architecture’s Professional Advisory Board and the Ardmore Historic Preservation Board.

Day Center Building | 1,575 SF | Ardmore, Oklahoma

The Grace Center of Southern Oklahoma is a homelessness prevention organization located in Ardmore. The organization's Day Center Building provides shelter, laundry, pantry, and restroom facilities for those in need. The Day Center Building underwent a significant remodel to update the interior finishes and rework the layout to make better use of the space. The existing pantry and storage areas were reorganized to maximize storage space for food and clothing. The layout of the lounge and lobby was modified to be more open and inviting, while also creating new controlled access points for security. SDG is proud of the important work the Grace Center does in the Ardmore community, and we are pleased to have donated our resources to the design of this project.


Chapel Schematic Design & Color Rendering | Approx. 2,000 SF | Ardmore Oklahoma

In 2014, SDG worked with Oak Hall Episcopal School to produce a schematic design and conceptual renderings for a new chapel building on their 14-acre campus. With a central location and unique oval shape, the new chapel building would become the anchor to the campus. The shape also allows for a 360-degree view of the pastor during services. The exterior of the building incorporates brick and stucco finishes to complement the existing campus style.
