Mariah's journey into healthcare was profoundly influenced by her mother, a dedicated nurse at RRH for three decades. Witnessing her mother's passion for patient care, Mariah was drawn to the medical field from a young age. Her interest was further solidified during a healthcare class in high school, confirming her desire to pursue a career in healthcare.

Born and raised in Ridgecrest, Mariah is a proud graduate of Burroughs High School. Her path took her to Greensburg, Pennsylvania, in 2014, where she embarked on her professional journey in healthcare. After honing her skills and gaining valuable experience, she returned to her roots in Ridgecrest in 2019.

Mariah's career began as a Medical Assistant in Greensburg, working on a Med-Surg/Oncology unit from 2014 to 2017. Her commitment and skill soon led her to become a Registered Nurse (RN) in the same community, initially as a Med/Surg nurse and later specializing as a postpartum nurse until 2019. Upon her return to Ridgecrest, Mariah joined RRH in Maternal Child as a charge RN, specializing in labor and postpartum care, a role she has proudly held from 2019 to 2024.

A unique and heartwarming fact about Mariah is that she was born in Ridgecrest Regional Hospital, bringing her journey full circle and underscoring her deep-rooted connection to the community she serves.
