Where Smart Home Buying Begins.

Hi, I'm Sonja Schuman.
I believe smart home buying begins with trusted guidance, honest advice, and having someone in your corner from day one.
Since becoming licensed in 2004, I've helped buyers, sellers, and investors navigate one of life's biggest financial decisions with confidence. My goal isn't simply to help you buy or sell a home - it's to help you make smart, informed real estate decisions that align with your goals, your lifestyle, and your future.
As a Broker Associate with The Cassina Group, I combine more than 20 years of experience with strong negotiation skills, local market knowledge, and a commitment to serving my clients with integrity and excellence. Whether you're relocating to the Charleston area, purchasing your first home, investing, or planning your next move, I believe informed clients make the best decisions.
Originally from the high desert of New Mexico, I relocated to the South Carolina Lowcountry in 2020, though Charleston has felt like home for much longer. After spending more than two decades vacationing here with family, putting down roots in Mount Pleasant felt like coming home. My husband, Daniel, and I are raising our three children here and are grateful to be part of this incredible community.
When I'm not serving clients, you'll often find me kayaking, creating something artistic, walking the beach, or serving alongside local non-profits.
I'd love the opportunity to help you start your own Buying Smart journey.

FAVORITE STREET IN CHARLESTON Church Street is my favorite because it perfectly captures Charleston's timeless charm. Every time I pass the Dock Street Theatre, I'm reminded of the city's rich history, beauty, and enduring character.
FAVORITE RESTAURANT IN CHARLESTON Oku is my go-to spot because their sushi is consistently outstanding, and their warm, attentive service keeps me coming back.
FAVORITE ACTIVITY OUTSIDE OF WORK Nothing recharges me more than spending time on the water with my family, soaking in the beauty of the Lowcountry waterways and the joy of being together.
FAVORITE LOCAL PRODUCT My favorite local product is Elu Cook Designs because every handcrafted piece reflects creativity, quality, and the unique beauty of the Lowcountry.
FAVORITE ANNUAL EVENT Nothing says Christmas in Charleston quite like the Holiday Market in Marion Square, where local makers, festive lights, and holiday cheer come together in one beautiful tradition.
MUST-SEE SPOT IN CHARLESTON For me, the Pineapple Fountain is more than a landmark - it's a place where Charleston's welcoming spirit shines as families gather and children splash, play, and simply enjoy being together.
