Program Coordinator - RetireRehire

Hometown: Mesa, Arizona

I love being able to help those return to work after retirement and making them feel at ease and letting them know that we will take good care of them. I worked at a district before ESI and was able to see the district side of things, so when employees have questions, I am able to better assist.

I used to coach high school volleyball for both boys and girls. This was a huge passion of mine - coaching has always had a huge place in my heart.

It's a dream come true to lead a company of caring people who create so much good for our community. Helping solve Arizona's staffing crisis in education and public service is deeply meaningful work.

I am blessed to see the positive impact our work creates for our leased employees, the districts and agencies we serve and, in turn, the people of Arizona whose lives are improved. It's an added bonus to see the way this work is uplifting for each member of our ESI corporate family.

Finance Administrator

Hometown: Fort Collins, Colorado

One of my favorite things to do is find issues and figure out solutions. This job provides ample opportunity for this in many different areas. I have a very linear brain so accounting makes lots of sense to me. Since I am also a problem solver, I continually look for ways to make things run more efficiently/effectively.

I take a deep breath when I have completed what I set out to do for the day - checking things off my list makes me smile. I also smile knowing I now have time to relax and recharge.
