Inside Our Classroom

CEO Shares Her Vision

Stephanie Thornton Plymale is the owner and CEO of Heritage School of Interior Design. Heritage is headquartered in Portland, OR, and also operates in Denver, CO and Seattle, WA and now offers an entirely Virtual Program. Heritage School of Interior Design is an intensive program designed to fully equip students for a career in interior design by combining a hands-on education with a full complement of technical courses.

Stephanie owned an independent design firm for eighteen years, serving hundreds of residential and commercial clients, prior to taking over Heritage School of Interior Design. Stephanie is also a mother of three and has been married for thirty years to her high school sweetheart. In addition to her career with Heritage, Stephanie is the best-selling author of American Daughter, her memoir, and recently founded the Heritage Home Foundation, which serves our foster youth and homeless community.

Stephanie’s greatest joy in owning and operating Heritage is fostering and promoting the success of its students. Heritage graduates over 100 students each year and these students have gone on to win prestigious awards and start wildly successful businesses and careers. A key reason for our success is the broader community support we’ve received for Heritage and its students.

Stephanie recently joined the Board of Directors for Humble Design and is the Decor Stylist for Link2Us Magazine.

It’s long been Stephanie’s dream to broaden the reach and impact of HSID, creating opportunities for more students in new locations. That desire has led her to create an opportunity for new owners to join the HSID team and share in the joy of changing lives and empowering the success of others with our proven methodology and the support of a team dedicated to your success.

Success Stories

Rhonda Larson, Alumni & Owner and Executive Director of HSID Denver, Colorado

Rhonda had always been a maker, finder and curator of beautiful things, an artist in jewelry and metalsmithing, mixed media painting, bookarts, collage and assemblage, and a natural designer. Her life took an exciting turn when she decided to turn her lifelong passion for design into her career and discovered Heritage School of Interior Design. At the time she enrolled she had no idea that she would become a vital piece of the school’s expansion to Denver. While in Portland, Rhonda became an independent interior designer as “RL Design Studio” and shop owner of “Velvet and Burlap Home”. Stephanie and Rhonda grew close throughout Rhonda’s creative journey which is when it became apparent that Rhonda was a perfect fit for an Executive Director role at Heritage’s first new location. Rhonda had been looking for excuses to move back to Denver so this couldn’t have been a better opportunity! Learn more about Rhonda here.
