Biography and education
I grew up in Houston, TX. My first degree is BS in psychology from the University of Houston. I later received a Masters in Education from the University of Louisiana at Lafayette and taught Kindergarten and first grade. I decided to change my career path and returned to the University of Louisiana at Lafayette to earn a BSRN through an accelerated program and then an MSN in the adult nurse practitioner program. I immediately enrolled at the University of Massachusetts at Boston to earn a post master's certificate as a family nurse practitioner. Upon completion of this degree I practiced as an FNP in the emergency department for 11 years. During this time I completed a DNP from Frontier Nursing University. Upon completing my DNP I was offered a faculty position and accepted. I worked in both the FNP and PMHNP programs at Frontier. In the FNP program I was course coordinator in a didactic course. In the PMHNP program I was Regional Clinical Faculty. I remained faculty at Frontier Nursing University for 8 years. In 2019 I completed a post masters certificate in Frontier's PMHNP program. I joined an established PMHNP outpatient clinic as a parter/owner. In 2023 I left Frontier Nursing University to join Texas State University as a Clinical Associate Professor in the PMHNP program and to cross teach in the FNP program.
