I love teaching 5th grade and enjoy the fun activities, and preparing students for life at CHMS! I have been at Walker in many capacities since 2005: parent, substitute teacher, and full-time teacher. It is an amazing school to work at with great teachers, families, and students.
My family has lived in Clarendon Hills since 2001, my husband Clay and I have three daughters: Grace, Chloe, and Jane. We have two dogs that are my walking buddies. I enjoy traveling, reading, chocolate, and all Chicago sports teams. We are going to have a great year!!

I am thrilled to be returning to 5th grade at Walker! It is a year filled with milestones and amazing adventures! I look forward to preparing this amazing group of 5th graders for CHMS and beyond!
This is my fourth year at Walker and I am no stranger to D181 as I attended Oak School and Hinsdale Junior High. Before returning to teaching full-time, I worked as a substitute teacher and nurse in all the district buildings for several years. I feel fortunate to be a part of the Walker and D181 community!
My family has lived in Western Springs since 2013, my husband Tim and I have three children: Jane, Jack, and Charlie. Outside school, I love spending time with family and friends, skiing, traveling, and reading. I am so excited for this year!

Hello Walker Wildcats! My name is Natalie O'Callaghan, and I am very excited to teach fifth- grade at Walker School! I graduated with my Bachelor of Science in Elementary Education from the University of Illinois at Urbana Champaign in May of 2019. Go Illini!! Each year it is so exciting and rewarding to see the academic, social, and emotional gains this age group makes. I cannot wait to meet and work with all of you!
Outside of school, I enjoy reading, doing craft projects, spending time with friends and family, and trying new restaurants!
