      Associate

      My passion includes working alongside our members and guiding them through their financial journey. With more than 25 years in the Financial Services Industry and more than ten years with Thrivent, one of my greatest strengths is the ability to listen. 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 teenagers, Michael and Christina, that are active with school, sports and work. My time is fulfilled as I help coach my daughter’s softball team, participate in community events and serve as an appointed trustee for our local police department’s pension fund. We appreciate the quiet time we occasionally have during the weekends when all four of us are home together.
