Prior to working with OCSN, I worked in the field of Occupational Therapy. Served as a rehabilitation director for many years. Assisted with the development of new rehab and wellness programs within the community. Also, started a family daycare, working with Great Start to Quality in the State of Michigan to become a star rated provider. Have been with Coopersville Area Public Schools in other roles for the past 5 years. During that time I worked with the Special Education team in programs from prek-12th grade, and provided direct Occupational Therapy services to students.

I love that every day is so different. I love that I get to support families, connect with my community and develop programs for our kids. I love that I get to be part of the bigger picture of what kids need to be successful and then help implement those things. I really enjoy making a difference every day.

Things that make me happy include spending time with my husband and our two boys. We love camping, boating and anything outdoors. If I get some quiet time, I enjoy reading-- just about anything, jogging, cross country skiing and all things art.
