Cassie Dieudonne

Growing up in a small town in Central Texas, Cassie Dieudonne learned the values of community, relationships, and hometown pride at a young age. Whether she was cheering on Friday nights at a high school football game or competing in High School Rodeo, her outgoing personality and love of competition shined through from a young age.


After graduating from Sam Houston State University, Cassie started her career in customer service and retail management, moved on to the insurance and financial services industry, and also worked at a non-profit professional association, before deciding to make her move to the real estate business. Each step of her professional journey has fueled her passion for sales and helping people, and through her experiences, Cassie has created many valuable professional and personal relationships. Her outgoing and approachable personality, along with her knack for building relationships with everyone that she meets, makes it simple for Cassie to cater to the needs of each individual client and deliver them an enjoyable experience and complete satisfaction.


Cassie has been married for 17 years and has lived in Katy for the last 13 years with her husband Aaron, and children, Vance and Sidney. She enjoys traveling, working out, decorating, drinking wine, and spending time with her friends and family. Cassie loves that she gets to call Katy, Texas her home and would love to help you find your perfect home too!
