I am sorry, an error has occurred.

Rose Zulewski

It is with great sadness that Advantage One announces the passing of former CEO, Rose Zulewski. Rose was with the credit union for over two decades, until she retired in 1999. She was instrumental in the growth of our organization and built a foundation that led to future successes. After her retirement, she continued to serve as a CU volunteer for many years. Rose was the sister to our current Board Treasurer, Bob Mattern.

The family will be holding a service for Rose at St. Vincent Pallotti in Wyandotte, MI.
