About Sonia Kingslien

Founder, The Kingslien Group | Designer | Investor

With a foundation in architecture and years of experience as both a real estate investor and home flipper, Sonia Kingslien brings a rare balance of design expertise, market knowledge, and investment strategy to every client relationship. She sees homes not just as properties, but as places of possibility — where lifestyle and legacy come together.

As the founder of The Kingslien Group, Sonia is dedicated to guiding clients with care, insight, and integrity. Her architectural eye allows her to uncover potential and value in every home, while her pursuit of the WELL AP certification reflects her commitment to sustainability and the future of healthy living.

Known for her personable approach and tireless work ethic, Sonia makes the process of buying, selling, or investing seamless and empowering. Clients trust her not only for results, but also for the warmth and clarity she brings to each step of the journey.

Beyond real estate, Sonia is a devoted mother, active community volunteer through the National Charity League, and finds balance in yoga, running, and Austin’s hiking trails.

At the heart of her work is a simple philosophy: real estate is more than a transaction — it’s about creating a home and a future that truly reflect who you are.
