Abby Refsland
FOUNDER & EXECUTIVE DIRECTOR
I believe that every student in the state of Minnesota should have access to school social work services and have an experience at school that is full of joy.
I believe that better student outcomes are linked to teacher well-being and a joy-filled, regulated school experience.
What I Do:
I am a Licensed Independent Clinical Social Worker and am also licensed as a School Social Worker.
I have been a social worker for over 20 years, most of that time was spent in schools as a school social worker and a special education coordinator, with some earlier career experience in hospital social work.
I currently supervise our team of 14 school social workers that support students from around the state of Minnesota.
I also coordinate Agate's professional development offerings and am working to support schools across the state with the new Third Party Billing and Medicaid Reimbursement for Mental Health in Special Education.
