About Us

Substitutes Any Time is excited to be making a difference in Arizona Public and Charter Schools, and Early Childcare Centers. Substitutes Any Time is a division of Teachers On Call, Inc., headquartered in Bloomington, MN. Teachers On Call was established 16 years ago in Phoenix, AZ and in Bloomington, MN. Since the owner was moving back to Minneapolis full-time, the Arizona branch was sold. Teachers On Call has since flourished in the Midwest. (“Teachers On Call—AZ” is now a separate entity, under separate ownership.)  Teachers On Call was acquired by Kelly Services® in September of 2017, and as a result, Substitutes Any Time was acquired as well.  From that point forward, the company will be known as Substitutes Any Time, a Kelly Services® Company, and will operate as part of Kelly Educational Staffing®. 

Teachers On Call has been serving the education industry for 16 years by providing substitute teachers, paraprofessionals, teacher's assistants, teacher's aides, as well as other types of educational and office support. Six years ago, TOC partnered with Frontline Technologies to deliver their automation, partnered with our substitute staffing expertise, to schools. Absence Management (formerly Aesop) is a nationally renowned automated substitute placement system, and anyone that partners with Substitutes Any Time will benefit from using this software.

We are excited to bring this same model, so successful in schools and districts throughout Minnesota and Wisconsin, to Arizona, doing business as Substitutes Any Time!

Substitutes Any Time is eager to provide our substitute staffing solutions to your Pre-K-12 schools. In partnership with the Absence Management (formerly Aesop) automation (we will connect you with Absence Management for set up if you are not currently working with them), Substitutes Any Time will utilize our unique staffing strategy, allowing your school or district to be as time-efficient and cost-effective as possible.
