Client Services Associate

After completing a financial services internship in high school, Lizy Castillo discovered she is passionate about helping people plan for their future. At MainStreet Financial Group, she is a new business and client services associate. Lizy facilitates a seamless and stress-free transition for new clients, as their investments move to MainStreet’s management.

Lizy is a great example of two of the most important financial planning principles: She is actively saving for her future and makes it a priority to eliminate debt. She is attending Northern Illinois University, where she’s a junior majoring in business. In her free time, she finds great joy in party planning and decorating to a theme.  At home, Lizy enjoys spending time with her daughter, her boyfriend of many years and their pets — a dog and two birds.
