Lisa Romero is a certified Family Nurse Practitioner. She attended Northern Arizona University and graduated summa cum laude in 2002 with her Bachelor of Science degree in Nursing.  She has a diverse seven years of experience in mostly emergency and trauma nursing. She later returned to University of Phoenix and graduated summa cum laude in 2009 with her Master of Science degree in Nursing with a focus as a Family Nurse Practitioner.  Her experience as a nurse practitioner includes working in a multi-specialty outpatient hospital group in rural Arizona for seven years and later opening her own primary care practice in Northern Arizona.  Though a difficult decision, she decided to close her primary care practice and return to the Phoenix area to provide more opportunity for her son and because she missed the warmer weather!  Lisa is excited to work alongside a fantastic team of providers to provide exceptional care to the ASU student population.  She loves sports and has always been a Sundevil fan and is excited to be a part of the Sundevil family.  In her spare time, Lisa enjoys traveling, attending sporting events (she is an avid football fan), going to concerts, and spending quality time with her son, Devin, and their family.  Go Devils!
