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. Read more about Stephanie here.

J.D. is a serial entrepreneur and designer with nearly 15 years of experience in the design industry. His experience includes high-end residential, light commercial, custom hardware, publishing, graphic and kitchen & bath design both on the West Coast and in the Midwest. With his original education and work experience in Corporate Accounting, J.D. is proficient in both the financial and technical aspects of the industry. 

After working in high-end residential design with another designer for several years, and while still in design college, he started his own residential and light commercial firm with his business partner/husband. What started as a desk in the corner of their apartment became an accomplished local firm serving clients throughout Central Indiana from a magnificent one-hundred-year-old home. 

During this time, J.D. also co-founded a successful publishing company that produced a local, county-wide home magazine created to not only serve as a marketing vehicle for the design firm, but also to support the community by giving small business owners a more affordable way to advertise directly to their target local market. 

After several years, J.D. and his family made the decision to sell everything and move to Seattle to facilitate the next steps in his career. A contemporary designer at heart, the Pacific Northwest and Seattle in particular, was the perfect choice. 

Now starting his sixth business, J.D. is excited to bring his knowledge and expertise to the students at Heritage.

Amy Troute is a 2008 graduate of Heritage and a top Interior Designer in Portland. She’s always had an eye for color and design and a passion for the comforts of home. Amy earned a Bachelor’s Degree in Communications and enjoyed a successful decade-long career in Marketing and Advertising. When Amy found out she was expecting twins in 2003, she knew she would continue to work after they were born but wanted to love what she was doing while she was away from them. She decided to pursue her passion for interior design. She built her portfolio over the first three years of her daughters’ lives with referrals from friends, and eventually met Jennifer Adams, an established designer and Heritage graduate. Jennifer hired Amy to work with her Portland clients and recommended she attend Heritage to gain the education she was missing.  Amy recalls Jennifer saying “you have about 80% of what it takes to be successful, Heritage will provide the rest.” After graduating from Heritage, Amy moved her design firm from home to a small studio in the Pearl District and the fledgeling “Design for Home” became Amy Troute Inspired Interior Design, a full service residential and commercial interior design firm working throughout northwest Oregon and southwest Washington. Her services range from furnishings design to specification and selection of surfaces and finishes for new construction and renovations. Amy was listed among the area’s “Top 15 Interior Designers” on in 2014 and was featured in Oregon Home Magazine in 2016, completing a Dream Bedroom Makeover for a lucky client in Washington.  Amy Troute Inspired Interior Design has been recognized as “Best of Houzz” for 2014, 2015 and 2016. Amy is truly inspiring and continuously supports the school by coming in each term to speak to new students and is always happy to provide insight to our graduates who reach out to her. We are so excited to welcome Amy to our Advisory Board!



Reyna Badillo has always admired art and fashion and she grew up in an environment where she learned a lot about the beauty of wood. She channeled her passion and knowledge for design into her own business, Summit Wood Creations, which specializes in custom, craftsman style furniture made from sustainable raw materials. After successfully running her business for 15 years, she wanted the opportunity to be more creative. She felt that her vision was limited to furniture and she wanted to be able to help her clients create a cohesive look in their home. She decided to take that next step by becoming more educated in interior design and enrolled at Heritage School of Interior Design. After graduating from Heritage, she had all the tools she needed to make her dream come true. Reyna now has her own manufacturing company which produces her line of sustainable furniture and she also offers interior design services. Her line of furniture includes custom kitchen cabinets, dining tables, bedroom furniture and more. She is committed to sourcing local wood and environmentally-friendly production practices. Her team draws inspiration from the inherent, natural beauty and rough, untamed texture of raw materials. Reyna is a perfect addition to our advisory board, we are so thankful to have her!




Michael was born and raised in Texas and had an apparent talent and passion for design at a young age. Growing up he would redesign his bedroom every couple of years, with his mom’s permission, with new paint, drapery, art and bedding. He loved rearranging furniture, redecorating and moving art around his house. Whenever his mother left the house she would come home to a rearranged and redecorated home – always a nice surprise! While Michael was in design school, he got his first job working in a trade showroom. He later started his own firm in addition to owning three retail stores. He did extensive traveling to do design projects for clients around the world. But in 2008, Hurricane Ike hit Texas. Damages from the Hurricane added up to $37.50 billion USD, the costliest hurricane on record. The hurricane destroyed his business and his home, in the midst of a recession so Michael was forced to restart in the toughest conditions. Michael decided to take a trip to Portland and quickly fell in love with it. While in Portland he started working with a client on a project and found out the furnishing and decor options in Portland were extremely limited. Being the entrepreneur that he is, he saw the potential for a showroom and created Nest. Nest Showroom caries over 10,000 fabrics to choose from and 50 other lines of designer products including upholstery, case goods, lighting, rugs and more. Michael is well-known throughout the design community and is a true expert in the field. He values long-term relationships and trust with his clients, which is apparent in the way he runs his business. He has been extremely supportive of the school and provides our students with invaluable knowledge. Michael’s advice for aspiring interior designers is to let your personality and style shine, be confident, work hard, listen to your clients, ask for help, do it right the first time, clean up mistakes and thank your clients.
