    Dr. Katharine Pace

    Mental Health Committee. Psychiatric-Mental Health Nurse Practitioner

    Dr. Katharine “Kate” Pace (DNP, PMHNP-BC) is a board-certified Psychiatric-Mental Health Nurse Practitioner dedicated to providing inclusive, compassionate, and evidence-based care that honors the whole person. She believes healing begins with connection, safety, and the experience of being truly seen, and she approaches each therapeutic relationship with warmth, respect, and genuine curiosity. Kate earned her Doctor of Nursing Practice from the University of Iowa, where she received advanced clinical training in diagnostic assessment, psychopharmacology, psychotherapy, group facilitation, and trauma-informed care.

    With more than a decade of experience spanning emergency nursing, mental health care, group therapy, and education, Kate brings a grounded, patient-centered approach to her work. She integrates evidence-based medication management with psychotherapy and holistic strategies tailored to each individual’s needs. Her clinical interests include anxiety, depression, trauma, ADHD, identity exploration, and major life transitions, and she is especially passionate about helping individuals reconnect with their resilience, strengths, and sense of possibility.

    A proud member of the LGBTQIA+ community, Kate is deeply committed to creating affirming care environments where identity is honored and diversity is celebrated. Her practice is shaped by cultural humility and trauma-informed principles, influenced in part by her clinical work on the Pine Ridge Reservation with the Lakota Sioux, where she gained a deeper understanding of intergenerational trauma and resilience. Kate has also been a strong voice in healthcare advocacy, previously serving as Director of Public Policy for the Iowa Nurses Association, where she led statewide initiatives to strengthen the nursing workforce, expand access to mental health care, and advance equity across healthcare systems.
