Nurse Practitioners

Julie MoreauAlice Whittington-Gulba

I started my career with a desk job and quickly realized working in an office wasn’t for me. I had several friends who were nurses and I began taking classes in the evenings after work. I loved interacting with patients and spent several years working as an ICU and labor & delivery nurse before deciding I wanted to do more to help patients – that led me to become a nurse practitioner.
