I am a Psychiatric-Mental Health Nurse Practitioner (PMHNP) who provides medication management across the lifespan, including children, adolescents, adults, and older adults. I have experience treating depression, anxiety, ADHD, bipolar disorder, other mood disorders, trauma-related symptoms, irritability, impulse control concerns, behavioral issues, emotional dysregulation, psychotic disorders, and substance use disorders, as well as supporting individuals who are in recovery.

I strive to create a supportive, respectful space where clients feel heard and understood. I also work with families and caregivers when appropriate to support continuity of care.

This is a telehealth practice. As a personal choice, the use of narcotics or other controlled (DEA) meds are minimal, if any. I've been a psych nurse practitioner for at least 14yrs. I believe in managing conditions with psychiatric and non-psychiatric treatment modalities that are evidence based. The use of the least amount of meds, at lower doses that does the healing of symptoms, is an active process involving the client and based on the reported experiences. Safety is the core of my practice and my job is to help clients understand internal signals and how to prevent another crisis.

As a Stanford-trained psychiatrist, I work closely with Dr. Sethi at Metabolic Psychiatry Labs (MPL) to manage serious mental illness conditions including bipolar, depression, binge eating disorder, and psychosis. While I am trained in multiple types of psychotherapy, including CBT, psychodynamic, DBT, ACT, and Internal Family Systems. I believe in treating the root cause of mental illness. I provide supportive therapy around your metabolic and psychiatric conditions using different therapeutic approaches.

I have over 27 years of experience in nursing and mental health care. I specialize in supporting individuals of all ages who are navigating anxiety, depression, trauma, grief, relationship challenges, and burnout.

I have a particular passion for working with caregivers, high-achieving professionals, and women who carry the emotional weight of others. My care blends evidence-based psychiatric treatment with holistic approaches to help clients achieve balance in mind, body, and spirit.
