Julie Boutilier-Berghorn

As the daughter of a full-time artist and small business owner, Julie Boutilier-Berghorn has never lacked ambition and has always been a visionary. In her twenties, Julie moved to Maine and began her secondary education at the University of Southern Maine focusing on small business studies. Moving to Washington DC 6 years later, Julie started working for an upscale luxury design firm. During this time, she realized she had a gift for designing unique livable luxurious spaces through her sensitivity to each clients' personal tastes and goals. Julie says, "It's about developing relationships, listening, and letting love guide the process." She realized designing livable luxury spaces could become a thriving business. After years of living in Washington, Julie moved back to Indianapolis in 1999, where she began working at her mother's design firm. She studied Interior Design at Purdue University and bought Cornerstone in 2012.
