Administrative Staff
Sherita Underwood
Administrator/Billing Specialist
Sherita is currently an undergrad student at the University of Illinois at Chicago (UIC), pursuing a Bachelor of Science degree, majoring in Psychology. She works in the AZ+A office, helping new families get started with therapy successfully. She most enjoys building new relationships and appreciates the culture within AZ+A allows her to learn as she goes and to grow.
In my free time, Sherita likes to read, listen to podcasts, and spend time with close family and friends. Her secret superpower wishes would be to fly, read minds, and have super strength. We already know that Sherita is super strong!
Erin Gilmore
Operations manager
Erin has become an integral part of AZ+A’s team. She holds a bachelor’s degree in Art and Psychology. Her favorite thing about being AZ+A’s operations manager is getting to talk to the kids when she does work in the playhouse. Sometimes when fixing or install things with a hammer or drill, it is to show whoever may be playing in the clinic what is going on.
Her time at the clinic and working with the OTs may be the catalyst for an occupational therapist career of her own one day! Erin finds the work and the AZ+A environment fun and exciting. At some point, she thinks she has discovered everything, and then one day she notices something entirely new, like an exciting toy that may have been hiding previously. If she has her dream superpower of telekinesis, she’d be able to move all the toys around with her mind!
During her time away from AZ+A, Erin creates illustrative artwork, some for herself and some for people to buy. She also likes to rock climb, bike, hike, read, and explore different cities (as well as Chicago)
Hera
Morale Booster
Hera is a 6yo English Lop. When not munching on lettuce or hay, she enjoys relaxing with some treats. She also enjoys running laps and jumping around her open space. Hera enjoys spending time at the clinic for the extra love, pets, and of course, treats. Hera loves allowing children the opportunity to care for her while she hangs out in AZ+A
Leo
Playhouse Therapy Pup
Leo has loved coming to AZ+A since he was 8 weeks old. You can usually find him in the office, courtyard, and occasionally the ball pit (when nobody is looking!) Leo is a therapy dog in training and loves snuggles, treats, and playing all kinds of games. Stop in and say hi to Leo for some puppy love!
