Instructors share interior design theory and application through their personal and professional knowledge. Each instructor has their own design business and have a wealth of design experience to share. The instructor’s passion for interior design is only surpassed by their passion for teaching interior design.


Stephanie brings her passion for empowering others and helping them grow personally and professionally to Heritage School of Interior Design. Her professional background includes 18 years as an independent interior designer with experience in commercial design, residential design, staging for realtors, and custom window treatments and furnishings. The knowledge she gained helped her to grow not only as a designer, but also as a leader and business owner. She also worked as a top producing in-home designer for Calico Home. After a successful design career, and a thorough understanding of the value of hard work, her passion turned from working as an Interior Designer to empowering and inspiring others. It was soon after this realization that she was given the opportunity to purchase Heritage School of Interior Design, and the timing couldn’t have been more perfect. Since purchasing the school she has utilized the rich history and success of Heritage to transform the program. She has integrated the artistic and creative elements and principles of design and its history with the business and technology of design. To support this transformation, she has developed several new courses, which provide students with the well-rounded education they need to succeed in the industry. Stephanie is currently an active member of the Oregon Entrepreneurs Network as well as a volunteer and speaker for Dress for Success Oregon. Stephanie is devoted to the highest quality education and making it accessible to anyone who wants to start or enhance their career in the interior design industry. She does this by providing the educational experience and ongoing support that students need to be successful.

She is currently serving her sixth year on the Board of Directors of the Portland Chapter of the Interior Design Society (IDS) as immediate Past President and Chair of the Swatched event committee.
