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.
