She realized there was a need for advancement within the field of mental health, due to the gaps in care that she had experienced. She found a passion for working to enhance mental health, which led her to go back to school to become a PMHNP (Psychiatric-Mental Health Nurse Practitioner). The school where she got her FNP and PMHNP had a focus on giving an opportunity to students in rural areas, who did not have as much access to schooling opportunities. This is where she became passionate about giving everyone an opportunity to be cared for and wanting to empower those who are in need. She has worked in inpatient facilities, outpatient facilities and school settings, where she has experienced many people in need of treatment. Her passion for helping people in need of care has only grown.
