Catherine Holmes is a board-certified Psychiatric Mental Health Nurse Practitioner and Pediatric Nurse Practitioner providing personalized psychiatric care for children, adolescents, and adults throughout Northern Colorado.

With advanced training in both psychiatry and pediatric primary care, Catherine brings a unique perspective to mental health treatment—particularly when evaluating how emotional, behavioral, developmental, and attention-related concerns impact overall functioning across the lifespan.

Catherine is committed to providing thoughtful, individualized care rather than a one-size-fits-all approach. She believes effective psychiatric treatment begins with listening carefully, understanding the whole person, and developing practical treatment plans tailored to each patient’s needs.

Her areas of clinical interest include:

• ADHD and executive functioning concerns

• Anxiety and mood disorders

• Child and adolescent behavioral health

• Developmental and social-emotional concerns

• Medication management across the lifespan

Catherine’s goal is to help patients and families gain clarity, feel supported, and move forward with confidence through evidence-based psychiatric care and collaborative treatment planning.

At Cato Psychiatry, Catherine strives to create a welcoming environment where patients feel heard, respected, and empowered throughout their care.
