I help sellers to position their homes to maximize value through strategic pricing and straight forward advice on how to prepare a home for market- ensuring the property shows at its best and attracts strong buyer interest from day one.

About Bryrie

As a fifth-generation Osceola County native, I’ve had the privilege of calling Central Florida home my entire life. Growing up on a working cattle ranch instilled in me a strong work ethic, integrity, and a deep appreciation for our community’s unique way of life. Now, as a wife and full-time Realtor®, I bring that same dedication and care to every client I serve. Whether you’re buying your first home, selling a property, or searching for your forever home, my goal is to make the process as smooth and stress-free as possible. With over 20 years of living in Central Florida, I know the market inside and out. From hidden gems to the latest new construction communities, I love helping clients discover the place that feels just right for them. Real estate isn’t just about transactions—it’s about people, relationships, and building a future. That’s why I take the time to truly listen, understand your needs, and advocate for your best interests every step of the way. If you’re ready to buy or sell in Central Florida, I’d be honored to help you turn your real estate dreams into reality.

Guidance through difficult buyer financing

Chris was absolutely amazing! We were faced with buyers that had difficult financing. He guided us through every step of the process. He kept us informed, and guided us on negotiations during all of the difficulties. His knowledge of the current market made our pricing competitive, and made sure we got showings an offers quickly!

Highly recommend

Stephanie felt like family through this process. She was great with communication, always kept us in the loop. She did all the necessary things to sell the house (brokers open, social media posts, giveaways) no corners were cut and was so professional every step of the way. She prayed with us and we got to lean on the Lord together. During a time of our lives that could have felt like a hard struggle, didn’t feel like that, Thanks to Stephanie! She will get the job done!

First time buyer. Erika went above and beyond for us!

Erika was very professional, understood our priorities and did not waste time. (FOUND OUR DREAM HOME WITHIN 1 WEEK!) .She gave us personal recommendations that would benefit us regarding price, locations, commodities, etc. Erika also helped us in negotiations and was available 24/7 if we had any questions. She has many reliable and affordable contacts for inspections and any other projects you want to do as a homeowner. She also responded our text quickly even when it was after regular work hours. She became our family’s go-to realtor and we will be buying our next properties with her.
