Welcome to the Team, Mary Bunch, NP!
We are thrilled to welcome Mary Bunch to the Cornerstone family as Mexico’s newest Nurse Practitioner!
Mary began her nursing journey in 2005 as a patient care tech at St. Louis Children’s Hospital. Since then, her path has taken her through Pediatrics, Women’s Health, Labor & Delivery, the Emergency Department, and Acute Care—each experience fueling her passion for helping others and her dedication to lifelong learning.
A proud holder of a Bachelor’s in Nursing, a Women’s Health Nurse Practitioner degree, and a post-master’s certificate in Family Medicine, Mary jokes with her family that she’ll never stop going to school—and she wouldn’t have it any other way.
Originally from St. Charles, Mary moved to Mexico in 2013 and is excited to return to care for the community once again through Cornerstone.
Outside of work, Mary enjoys life with her husband Derek, who serves in the National Guard, and their three children—Peyton, Kaili, and Aubrie. Together, they love traveling, especially hiking through National Parks or relaxing at the beach. With an additional degree in Photojournalism, Mary also has a passion for photography and scrapbooking their adventures.
Please join us in giving Mary a warm welcome, Cornerstone is lucky to have her!
