A Lifespan Approach to Care

As a provider certified to treat patients across the lifespan, Markie offers a unique continuity of care. She understands that mental wellness looks different at every stage of life—from the developmental challenges of childhood to the complex transitions of adulthood. Her practice is defined by individualized treatment planning, ensuring that every patient receives a roadmap to recovery that respects their unique history, strengths, and long-term wellness goals.

Advocacy for Rural Wellness

Coming from a Wyoming background, Markie is acutely aware of the barriers to care often faced in rural and underserved areas. She views her role not just as a prescriber, but as a patient advocate who works to bridge the gap between clinical excellence and local accessibility. At Montana Psychiatry, she focuses on building strong therapeutic relationships, ensuring that every patient feels heard, valued, and empowered throughout their treatment.

Collaborative & Science-Driven

Markie’s clinical philosophy is rooted in collaboration. She believes the best mental health outcomes are achieved when the provider and patient work as a team. By combining the latest evidence-based research with a deep respect for the "human element" of medicine, she provides a balanced approach to psychiatry that is as scientifically rigorous as it is empathetic. She is thrilled to bring this dedication to the Billings community and help her patients achieve lasting health.
