Dr. Tollander takes a personal approach with each client to assess and meet their individual needs and emphasizes the importance of the therapeutic relationship part of the healing process.

Danell Bjornson

Co-Owner, Psychiatric Mental Health Nurse Practitioner

For the past several years Danell has been treating adults and children with a variety of psychiatric issues in an outpatient mental health clinic.

A commitment to helping clients obtain a comprehensive evaluation, accurate diagnosis, and evidence-based care led her to co-found Northwest ADHD Treatment Center.
