My nursing career started out in the Army. This experience provided me with a strong foundation of adaptability, discipline, integrity, leadership, teamwork, and enthusiasm. I continue to build upon this foundation throughout my life. I started out my NP career in electrophysiology in 2012. EP is my passion as it is constantly advancing to improve patient care.
