About
I’m a Realtor® based in Edwardsville, helping people buy and sell homes throughout the Metro East and nearby Missouri communities.
I take a thoughtful, strategic approach to every move—whether it’s pricing a home, marketing it effectively, or negotiating the details that matter most. My goal is to make the process feel clear, well-managed, and aligned with what matters to you.
Clients often tell me they appreciate my communication, attention to detail, and the level of care I bring to each step. Whether you’re buying, selling, relocating, or building, I’m here to guide you through it with confidence.
If you’re thinking about your next move, I’d be happy to help you get started.

If you’re looking for a real estate agent who knows the actual market and actual homes but keeps things fun, Sandie is your person! Sandie is smart, responsive, on top of every detail, and somehow makes the whole process feel way less stressful!
Sandie answered all our questions, if there was an unknown we always had a follow up, kept everything moving smoothly, and made us feel totally confident from start to finish.
Bonus: we discovered we share an extreme love for pizza 🍕 — which clearly means Sandie has excellent taste in both homes and food!
We’d recommend Sandie in a heartbeat!

I cannot recommend Sandie enough as our Realtor in selling my mother’s home of over 45 years. She managed an unusually high number of involved parties with ease, keeping everyone on track and ensuring we met our goals and closing date despite multiple challenges and hurdles. Sandie is patient, thoughtful, determined, creative, knowledgeable and exceptionally well-organized—all traits you want in any real estate transaction, whether simple or complex. We deeply appreciate everything she did for us. Sandie is a true gem!
