Robert A. Stinson

Architect Emeritus



CEO (Chief Entertainment Officer)




In 1988, Susan founded CDG Interior Design + Architecture (Chelsea Design Group, Inc.), in the Century City area of Los Angeles.  The firm has grown as a direct result of its superb customer service, supporting local, regional and international clients in reaching their goals.  Since commencement of her career in 1983, she has planned and designed successful environments for a broad range of clientele including corporate, legal and entertainment industry tenants, property management/ownership firms and federal and local government agencies, as well as non-profit organizations that offer housing and healthcare services.  Together with co-founder, Robert A. Stinson, AIA,  the firm has specialized in offering full scope architectural, planning,  interior design and technology services,  to support and integrated design process where all elements are coordinated by a cohesive in-house team. 

Susan is registered as both an Architect and Certified Interior Designer in California. She is a professional member of the American Institute of Architects and the International Interior Design Association. The firm focuses on providing personalized service that delivers projects, which are creative, functional, and respectful of budget and schedule requirements. Susan graduated from the University of Texas, in Austin, in 1982, with a Bachelor of Science degree in Interior Design and a Bachelor of Business Administration in Marketing.  She then joined Regency Development Company in Houston as a space planner within the Department of Architecture.  This experience gave her an in-depth understanding of commercial real estate and the important role that effective space planning plays in a successful lease transaction, as well as the foundation from which architectural and design solutions are developed.


After transferring to Los Angeles in 1986 as part of a development team to renovate, space plan and lease a 450,000 sq-ft commercial property, Susan joined Reback Design Associates as a Project Manager.  While there, she was responsible for the space planning and design requirements of several West Los Angeles properties.  Successful relationships with commercial real estate brokers and satisfied clients supported her goal to establish the firm in 1988. Many of these initial contacts continue to refer consistent business to CDG today.  We believe that the greatest value within the business community is long-term, trustworthy relationships that are mutually supportive for all parties. 


Susan has served as Chairman of the Board for the Century City Chamber of Commerce.  As past Co-VP Advocacy, on the SoCal Board of International Interior Design Association (IIDA), she continues to participate as an ongoing professional member, she supports endeavors to advance the profession through outreach efforts to educate the public and legislation about the role of the interior designer in the design of commercial environments and the value of future licensing for commercial designers.  Concurrently, Susan maintains professional membership status with the Los Angeles chapter of AIA.  Susan has received commendations from the City of Los Angeles for outstanding community service.  She feels immense satisfaction from helping people and businesses improve their quality of life by contributing to efforts that support our community and the well-being of its citizens.


Susan makes her home in Sherman Oaks, CA enjoying the ‘empty nest’ while her daughter pursues her post-college career goals. She enjoys hiking, travel, sailing, coffee, wine, and spending time with friends and family.
