Licensed Architect / Inspired ADUs
Carrie is the Principal at Inspired ADUs and Larson Shores Architecture & Interiors. She dedicated to timeless architectural and design excellence rooted in a sense of place and purpose. She is a licensed architect and LEED AP, who received her master’s degree in architecture from UC Berkeley. Carrie’s fierce commitment to ADUs and aging in community began when she, herself, faced serious spinal problems. She realized, firsthand, that her home was fighting rather than supporting her. The wisdom gained from her 10-year battle for wellness and personal independence opened her eyes to the environmental needs of the disabled and elderly, and informs every Inspired ADU.

Builder / That ADU Guy
Derek is a real estate investor and ADU builder over 25 years experience in the building/development trade.
His first ADU build was a high school project in 1996. That led to a carpenter apprenticeship and a career as one of the youngest licensed building contractors in Oregon.
Derek founded ThatADUGuy.com and began an open-source video series designed to guide homeowners through the process of building or converting their own ADUs. As a pioneering ADU developer, builder, and investor, Derek brings one of the most comprehensive skill sets to any ADU discussion or instruction. He spends his days running, skiing, talking about ADUs with homeowners, policy makers, builders, and anyone else who will listen.
Derek is a content developer and instructor for ADU Specialist trainings.
