Cassandra Noien is a trusted Sugar Land and Greater Houston REALTOR® with over two decades of experience helping families buy, sell, and invest with confidence. As part of the award-winning Audra O’Neal Team at ONTX Realty Partners, Cassandra is known for her deep local knowledge, strategic pricing expertise, and client-first guidance from start to finish.

She has successfully represented hundreds of clients in Sugar Land, Richmond, Katy, Missouri City, and surrounding areas — specializing in luxury homes, relocations, first-time buyers, downsizing, and new construction.
