Associate

My passion includes walking alongside our members, guiding them through their financial journey. With more than 30 years in the Financial Services Industry and more than 15 years with Thrivent, my greatest strengths include the ability to listen and understand our clients' goals. I enjoy growing through challenges and succeeding together. The financial confidence we have provided our members is validated as we receive introductions to their family and friends.


My husband and I were married in 1998 and have two adult children, Michael and Christina, that make us proud every day. My time is fulfilled as I participate in community events and serve on the boards of our local police department’s pension fund and our park district.
