Catherine Donnerstag, NP, is a Board-Certified Nurse Practitioner at Gladwell LLC, a psychiatry and mental health practice in Renton, Washington. Catherine provides high-quality and compassionate care via telehealth in Maryland and Washington, with an on-site office opening in Seattle soon.

Catherine always takes a traditional and evidence-based approach to care. Her style of practice also involves lifestyle modifications, therapy, and medication management. 

She is kind, patient, and qualified to practice psychiatry, including diagnosing, treating, and prescribing medication for children, adolescents, and adults.

Catherine specializes in diagnosing, managing, and treating numerous conditions, including attention-deficit/hyperactivity disorder (ADHD), depression, anxiety, panic attacks, insomnia, schizophrenia, bipolar disorder, addiction, and substance use disorder.

She is on a mission to simplify access to high-quality, affordable mental health care for all her patients. General mental health care that makes sense.

Catherine understands mental health care is a very intimate and highly personal experience. There's no one-size-fits-all approach to high-quality care. She invites you to allow her and Gladwell LLC to assist you in finding a therapist that is a good fit for you and your unique needs.
