Ms. Cortnie

Hello and welcome. I'm so happy you're here.
I’m Ms. Cortnie, and I’m thrilled to begin my 13th year in education, my 4th year teaching developmental preschool, and my 1st year teaching in the SCORE program. Teaching young learners is truly my passion, and I feel incredibly lucky to spend each day helping children learn, grow, and discover just how amazing they are.
I earned my Bachelor's degree in Educational Studies from Grand Canyon University and my Master's degree in Autism Spectrum Disorder. I'm currently attending Arizona State University, working toward my ABA degree to become a Board Certified Behavior Analyst (BCBA), because I believe learning is a lifelong adventure.
When I'm not in the classroom, my favorite place to be is with my family. My husband and I have been together for 19 wonderful years, and we have two amazing daughters, ages 22 and 19, who will always be my greatest accomplishment. Our family recently welcomed our very first grandbaby, who has quickly become the center of our world and fills our days with so much joy.
In my free time, you'll usually find me curled up with a great book, making memories with my family, or enjoying the outdoors. I love finding joy in life's little moments, and I bring that same sense of wonder, creativity, and fun into my classroom every day.
I can't wait to welcome your child into our classroom family. This year will be filled with learning, laughter, exploration, new friendships, and so many unforgettable moments. I look forward to partnering with you to help your little one shine.
Welcome to Ms. Cortnie's Critter Crew and I can't wait for an amazing year together.

Lisa Jemsek
Hello! My name is Lisa Jemsek, and I’m so excited to be entering my fourth year teaching developmental preschool at Sunset Ridge. I’ve been working in education for over 20 years, with previous experience teaching both kindergarten and first grade. Helping young learners build confidence, celebrate milestones, and discover a love for learning is truly one of the greatest joys of my career.
When I’m not in the classroom, I’m a proud wife and mom to three amazing kids. Our family is deeply rooted in the Sunset Ridge community, one of my children attends Sunset Ridge with me, one attends Boulder Creek High School, and my oldest graduated from Boulder Creek this year and will now be working right alongside me as a paraprofessional in our classroom. It’s such a special season for our family, and I couldn’t be more excited to share it with our students.
Being both a teacher and a parent in this community gives me a unique appreciation for the relationships we build with our families. I believe that strong partnerships between home and school help children thrive, and I look forward to getting to know each of you throughout the school year. Thank you for trusting me with your little ones. I can’t wait for a year filled with learning, laughter, growth, and so many wonderful memories!
