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. Part of that includes helping clients find a balance between wholeheartedly accepting themselves and changing what they can.

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. Much of her practice was spent learning how to screen for other causes of attention problems such as depression, anxiety, stress, and fatigue. 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. She earned a Master of Nursing degree from Oregon Health and Science University. Danell is nationally accredited in adult and family psychiatric mental health.
