I  started my Nursing career as a psychiatric nurse and worked my way up. I received my Master’s degree and Post-Master's Certificate as a PMHNP at the University of Texas Rio Grande Valley (UTRGV). Early in my career I was usually put in the position of leadership and mentoring therefore to utilize those skills. I am currently part of the Faculty at UTRGV PMHNP post-master’s certificate program as a clinical assistant professor.

Embracing change and finding the knowledge to navigate charter waters is one of my unique qualities.
