My Team


Giselle (Andrade) Manhollan

Practice Coordinator/Surgery Scheduler

Hello, my name is Giselle and I come with 30 years of experience in health and wellness Which 16 of that has been in spine surgery scheduling and patient care coordinating.

During my personal time I like to travel with my husband and visit places I’ve never been. I spend a lot of time playing softball and I currently play on a women’s gold travel team nationwide.

I chose to be in the medical field, due to my Passion for caring for others and helping them with their journey to recovery.
