Heather Tollander

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. Over time she developed a specific interest in treating ADHD as many of her clients, regardless of age, profession, or educational background presented with problems concentrating.

When ADHD was truly the primary diagnosis, she collaborated with her clients to optimize treatment. Over time it became increasingly apparent to her that medication alone was rarely sufficient to treat all problematic symptoms of ADHD. She feels strongly that both children and adults have the best outcome when medications are paired with skills training, education, and individual therapy. A commitment to helping clients obtain a comprehensive evaluation, accurate diagnosis, and evidence-based care led her to co-found Northwest ADHD Treatment Center. Danell graduated magna cum laude with a Bachelor of Science in Psychology, University of Mary Washington and magna cum laude with a Bachelor of Science in Nursing, Oregon Health and Science University.
