Making the world a better place one child at a time.

We spent every waking moment working toward improving & growing our business, paperwork, painting, caring for the children and dreaming.

Founded in June 2004 by owners Ashleigh and Ryan Zimmerman, Aa to Zz is a family-run business led by people who are hands-on, involved and passionate.  The first center in Harrisburg opened its doors with just two children enrolled – one being the Zimmerman’s oldest son.

The center expanded in the next few years to five centers and continued to grow. “Our initial success was thanks greatly in part to the endless amount of energy we poured into our first center,” says owner and co-founder, Ashleigh Zimmerman.

Making the World a Better Place, One Child at a Time

As a busy caregiver, you depend on your child care center to nurture your child in a safe, fun and enriching environment.  At Aa to Zz Child Care and Learning Center, our mission is to help your child thrive through loving care and developmentally appropriate activities that stimulate cognitive, social and emotional growth.  Our Harrisburg and York area child care centers offer reliable full-time, part-time, drop-in, summer camp and before-and-after-school care for families in the central Pennsylvania region.  When you choose Aa to Zz, together we’ll make the world a better place, one child at a time.

Aa to Zz Child Care and Learning Center offers the loving, caring and nurturing experience your family deserves.  We believe keeping children safe in a fun and rewarding environment leads to natural opportunities to learn — whether cognitively, physically or socially.  Your child will flourish in our hands-on, play-based environment, where outdoor play and building, climbing, exploring and discovering are on the agenda every day.  We believe so strongly in our screen-free, nature-based curriculum that we ignored classroom-ready programs and developed our own instead!

I wanted to thank you so much for working with me with moving my son to your location in Hummelstown.  As a parent, it makes my day to see my son happy.  When we pick him up from daycare, [he] always says, without us even asking, that he had fun and wants to come back.  When I drop him off in the morning, I always walk in on a structured activity such as a walk outside, a reading circle, or an art project.  It is so nice to see [his] room decorated with the children’s artwork.  Please let your teachers know how much I appreciate their hard work!

I just wanted to let you know that when I had my conference with Ms. Aurelia this morning, she made a comment that [my son] has made such an improvement and that we (Mike and I) should “keep doing what we are doing.”  Well, as a parent I hate to admit it but we really haven’t been doing much with [my son] at home as far as his letters and numbers……..it is ALL her!  She has done such a great job with [my son] and we appreciate her hard work so much!!  We are confident that she has prepared [my son] for kindergarten and we are not worried about his ability to thrive in his new school setting!  THANK YOU MS. AURELIA!!!!

Aa to Zz operates eight centers across Dauphin, Lebanon, & York Counties.  Aa to Zz’s facilities are unlike any other in the region.  Whether you’re considering our child care center in Hummelstown or our Palmyra preschool program, you’ll find classrooms stocked with toys made from natural materials such as wood, felt and silk.

You won’t find televisions, VCRs or DVD players because research clearly demonstrates that screen time does not benefit children.  Your child will spend time outdoors every day, regardless of the weather, getting their hands dirty.  With outstanding care, large outdoor playgrounds and safe and secure facilities, it’s no wonder Aa to Zz is consistently named one of the top preschool programs in the state by the Central Penn Business Journal.
