Adriane Nelson

Nurse Practitioner

Adriane has been the nurse practitioner at Craig Ranch Pediatrics since 2010. Nurse practitioners are registered nurses who have completed extensive additional education, training, and have a dramatically expanded scope of practice over the traditional RN role. Nurse Practitioners treat both physical and mental conditions through comprehensive history taking, physical exams, ordering and interpreting diagnostic tests. NPs can then diagnose the disease and then provide appropriate treatment for the patients, including prescribing medications. NPs make prevention, wellness, and patient education priorities.

Adriane grew up in Garland, TX and graduated in 1995 with a Bachelors of Science in Nursing from Baylor University. She worked as a neonatal intensive care nurse until she returned to school to become a pediatric nurse practitioner. Adriane graduated in 2009 from Texas Woman’s University with a Master’s of Science in Nursing. Adriane is an active member of her church where she volunteers in missions and participates in a bible study. She is married and has two boys, Alex and Ben. Adriane spends her free time scrapbooking and reading books nominated by her book club.

Melissa has been with Craig Ranch Pediatrics since 2008. Before coming to Craig Ranch Pediatrics, she worked in child care for 8 years, so she has a lot of experience with children.
