Hello, my name is Joelle Charpentier, APRN, PMHNP-BC. I am a psychiatric nurse practitioner who believes everyone deserves to feel heard, supported, and understood. I work with children, adolescents, and adults facing challenges such as anxiety, depression, ADHD, mood disorders, life transitions, and women’s mental health concerns. My goal is to provide a welcoming, judgment-free space where we can work together toward lasting wellness.

I am Jamila Warner, a Board-Certified Psychiatric Mental Health Nurse Practitioner dedicated to providing accessible, high-quality care that honors your unique journey. My approach is focused on creating harmony and order in the face of life's everyday challenges. I specialize in the diagnosis, treatment, and management of patients suffering from various mental illnesses including, but not limited to ADHD, mood disorders, anxiety disorders, and psychotic disorders.

I'm Anissa, a Board Certified Psychiatric Mental Health Nurse Practitioner specializing in the evaluation and treatment of ADHD and other co-existing conditions.

When you work with me you get care that is calm, attentive, and centered on you.

Who I Work With:

I support individuals who are struggling with poor performance at work/school, anxious thoughts, panic attacks, depressed mood, occupational burnout, and other related conditions.

You're in the right place if:

✓ You're constantly overwhelmed or stressed about upcoming events or tasks needing to be completed

✓ You've been working harder to keep up but you feel like you're failing and burning out

✓ You suspect you have ADHD and need an evaluation, or you've been told you don't have ADHD and would like a second opinion

✓ You need help getting school or workplace accommodations or a leave of absence due to mental stress

✓ Past providers rushed you or didn't listen to your concerns

Mental health care should feel like a conversation, not an interrogation.

I believe the best outcomes happen when patient's feel heard, respected, and are actively involved in their treatment. My approach involves a team approach and is honest and hands on. I take the time to understand the whole person —not just a diagnosis— so we can create a treatment plan that fits your goals, values, and lifestyle.

You are the expert on your life. I’m the expert on mental health. The best care happens when we combine both.

My path to psychiatric care is a little different from most. I spent over a decade as an Obstetrics Nurse before transitioning into psychiatric mental health — and that background deeply shapes how I show up for my clients. I understand the weight of life transitions, the complexity of the mind-body connection, and the importance of feeling truly supported. Now, as a PMHNP, I bring that same compassionate, whole-person perspective to mental health care.

Accepting new patients in MONTANA ONLY. I’m a board-certified Psychiatric-Mental Health Nurse Practitioner and founder of Gage Holistic Psychiatry, committed to providing personalized, holistic care. I specialize in integrative and functional psychiatry, working with LGBTQ+ clients and those navigating hormone-related changes such as perimenopause, menopause, and gender transition. My goal is to treat root causes—not just symptoms—for lasting mental wellness.

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.
