What parents and teachers are saying


All I can say is…BRAVO. I was and am still blown away by your VR lesson covering the Cold War for my eighth graders. When we walked in you had amazing Rusian music playing to get us amped for our virtual experience. 

Your procedures were spot on in handing out the googles and cleaning and putting them away. 

The boys were engaged 100% of the time. I think our favorite was when we went to Berlin. Just beautiful. Your knowledge of the material presented was clear and precise. You tied in so many wonderful experiences that our 8th-grade boys will remember forever.  

I heard comments like:

“This is amazing”- I didn’t know that Russia was like this”- “Is that an actual piece of the Berlin Wall” “Wow, cool”.

VR is an essential piece of the technological process to take our scholar’s learning to a whole different level. We are truly grateful to have you as our VR teacher among other things.

Thank you again,

Jori Bielski

P.S. Your Russian accent still brings a smile to my face!

I just wanted to take the time to thank you and your staff for serving your students day in, day out and keeping them safe. Particularly when it comes to drop off and pick up. Your staff is out there every day with smiles on their faces, in the hot weather, morning and afternoon, making sure our children arrive/depart to/from school safely and that pick up and drop off is made as hassle-free as it possibly can be. My hat is off to the staff who are out there every day making it as cohesive as possible. THANK YOU!!!!

As a parent, I really love GIA school. Not only do they have a great curriculum but they work with the kids one-on-one when they have issues be it educational or just personal. All kids are different and they let the kids be kids while being educated. My son loves going to school because of their staff. I honestly hated going to school many moons ago and wish I would’ve attended a school like GIA. Principal Patty Sturm Messer is very hands-on as is the rest of the staff. My 4 year old will start kindergarten there next year I hope.

I’ve noticed the difference in my children’s overall happiness. I think it’s indicative of the teachers being allowed to pursue their passion of teaching. We are satisfied with being the parents of two children who attend.
