A graduate of the University of North Dakota, Lance began as a psychiatric RN in acute inpatient settings before becoming a psychiatric RN supervisor in a major Houston hospital while pursuing advanced practice.

After becoming a PMHNP, Lance initially worked with outpatient addiction treatment and severe mental illness populations, later expanding into bariatric psychiatry to support patients preparing for weight-loss surgery. When the COVID-19 pandemic paused bariatric procedures, Lance founded a private practice—Grey Matters Mental Health—in Seattle, which was later sold to a larger healthcare organization in Minnesota. Lance then transitioned into correctional mental health, serving underserved populations within the criminal justice system. Currently, Lance is working at Talkiatry, providing compassionate, high-quality care informed by experience across diverse and challenging environments.

Lance understands that every patient is unique. His approach is grounded in Carl Rogers’ principle of unconditional positive regard, creating a safe, calming space where patients feel heard and valued.
