Matrix Mental Health

Psychiatric Nurse Practitioner

K Barber

As a Psychiatric Nurse Practitioner, I’m passionate about helping individuals navigate challenges, rediscover their strengths, and move toward a fulfilling, balanced life. I strive to create a supportive space where growth, healing, and resilience can thrive.

After completing Associates nursing degree at Scottsdale Community College in 2017 and subsequently completing my Bachelors of Nursing at Arizona State University in 2020, I spent most of my nursing career as an Intensive Care Unit nurse at Banner University in Phoenix. There I gained strong skills in critical thinking, clinical judgement, patient advocacy, and managing high stress environments. Throughout my journey as an ICU nurse, I began to develop a strong passion for not only caring for individuals physical wellbeing, but prioritizing individuals as well as their loved one’s mental health during some of the most vulnerable times in their lives. I pursued and completed my Masters in Nursing Psychiatric Mental Health Nurse Practitioner at Purdue University in 2025.
