Samantha Hartmann

3rd Grade Teacher

I am so excited to be in 3rd grade at Samuelson.  Here is a little about me: My husband works at Iowa State at the Bio Century Research Farm. We have 2 kids, Addie and Alex.  We also have a dog named Annabelle who is a Cavachon (small, white, & fluffy).  I grew up in the Chicago Suburbs and graduated from North Central College in Naperville.

Marisa DeVito

2nd Grade Teacher

Hi! My name is Marisa DeVito and this will be my 5th year teaching 2nd grade here at Samuelson. I graduated from Drake University in 2019 with a BSE in Elementary Education, a Reading endorsement, and a minor in Leadership Development. I am currently getting my Master’s in Culturally Relevant teaching through Drake University. I always love to find new ways to grow and educate myself alongside my students.

I believe in creating a space where students feel safe and supported and know that they are cared for every day. I want students to feel comfortable to take risks in learning, understand that mistakes are part of our educational journey, and believe in their ability to learn as much as I believe in them. I am looking forward to a wonderful year of learning ahead 🙂
