As a Board-Certified Psychiatric Mental Health Nurse Practitioner at Rooted Willow, I specialize in the medication management of mood disorders including major depressive disorder and bipolar disorder; anxiety disorders including obsessive-compulsive disorder, generalized anxiety disorder, social anxiety disorder, and panic disorder; attention-deficit/hyperactivity disorder; and post-traumatic stress disorder. My practice fosters a collaborative environment where clients' input is valued, and treatment is adjusted to align with their personal goals and progress. Rooted Willow is LGBTQIA+ friendly and an advocate of neurodiversity.
I focus on providing care to adults aged 16 and up, including women who are pregnant or in the postpartum period, offering compassionate support for the unique mental health challenges they may face. My treatment approach is comprehensive, addressing not only mental health but also the impact of overall physical health, and underlying medical conditions.
With individualized medication management, each client receives tailored care that supports their unique mental health needs. My practice does not support long-term benzodiazepine use, and I help patients find safer, evidence-based alternatives. If seeking ADHD medication, past medical records or psychological testing may be required.
