"Happiness might not be the end of your work, but happiness might be the means. And ‘happiness’ here is not defined as pleasure, but it's the joy you feel moving towards your potential in the midst of a broken world." - Shawn Achor on the power of rational optimism and joy!

Thank you to our 8th grade team for leading our learners through this reflection and introspection with the atrocities of the Holocaust as a backdrop. This is how we learn from the past. #YouBelongInD12
8th-grade students will start exploring the theme of identity in times of adversity by reading literature inspired by the Holocaust and World War II. Through these stories, they will be analyzing characters to answer the essential question: Who are you in crisis? #YouBelongInD12

Executive coaching is rooted in neuroscience, psychology, and behavioral science. It’s not just advice; it’s a structured process that helps leaders hone and refine their skills. Coaching isn’t a luxury—it’s a necessity! #LeadWithGrowth
