Front Office AdministratorRead Bio
Front Office Administrator
Moved from Louisiana in 1998. Fell in love with the many outdoor activities Tucson had to offer and decided to make it home. My biggest joys in life are spending time with my family and watching sports; especially the Dallas Cowboys! I previously was an office manager for Debra Walter, M.D. for 19 years. My most rewarding experience came from being a part of the patients’ care. Each one became like family to me and knew that whatever needs they had, I would go above and beyond to help. In my spare time, I also enjoy photography, reading, and cooking.
