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.

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.

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.
