Meet Karen Byroick
I am part of the Learning Support services team at Centennial Academy and provide school psychological services to students. I have been working with the Centennial students since 2002. Our time together is spent building self-image, expanding social skills, learning coping strategies and understanding feelings. Prior to working in Littleton, I was a school psychologist for the Douglas County School District. I received my Bachelor’s of Arts degree in Psychology and Computer Applications from the University of Notre Dame. While at Notre Dame, I was a competitive swimmer and an avid football fan. Go Irish! After graduating, I continued my education at the University of Denver. I received my Education Specialist degree in the area of School Psychology for children grades K-12. Outside of work, I spend time coaching swimming to young children who are part of the ACES Swim Club. Needless to say, I spend a lot of my day with children! I currently live in Littleton with my husband and two dogs, Raleigh and Roxi.

Days at Centennial: Monday, Wednesday, Thursday

Meet Nancy Zizzo
I am so excited to begin my 19th year as a school psychologist!  Although I’ve lived in Colorado for nearly 30 years, as soon as I open my mouth, it’s pretty easy to figure out that I’m originally from New York! I was born and raised in Queens and graduated from Queens College with a Bachelor's degree in Psychology and Anthropology. I am intrigued by cultures, traditions, and beliefs. I also have my Master’s degree in School Psychology from Queens College.  Prior to working for Littleton Public Schools, I have worked as a school psychologist in New York City, Long Island, Grand Junction, Denver, and Douglas County. I enjoy supporting students in reaching their goals by using out-of-the-box approaches, such as drama skits, puppet role-plays, games, and other hands-on activities. I also find it fun to collaborate with staff to teach social-emotional lessons. I’ve had such a great time dressing in costumes, hamming it up, and getting silly and creative, while engaging students as they learn new strategies.  My husband and I have three daughters. Two of our girls are in college and my oldest has recently graduated. We enjoy shopping at international grocery stores, trying out new recipes, and eating adventurous food! I also enjoy hiking and getting creative! I look forward to starting my new adventure, with my Potato Head friend, at Centennial Academy of Fine Arts!!
