At the age of 13, Sage’s family relocated to East Petersburg, marking the beginning of their journey as a student in the Hempfield School District. The transition to this markedly different educational environment provided Sage with valuable opportunities to engage with a wide range of voices and viewpoints, broadening their horizons beyond their city upbringing.
In 2019, Sage proudly graduated from Hempfield High School and continued their academic pursuits at Thaddeus Stevens College of Technology. Throughout their time at Thaddeus Stevens, they remained an active and engaged student leader, serving as Vice President of the Student Government Association where they managed responsibilities including event planning, collaborative leadership, and budgeting. Their dedication and leadership earned them the honor of delivering the commencement speech at the 2022 TSCT graduation ceremony.
Sage is also a graduate of the 2022 Leadership Lancaster Core Class. Their experience with Leadership Lancaster provided a renewed perspective on Lancaster County and ignited a deeper commitment to community leadership, civic engagement, and collaborative impact. Today, Sage serves on staff at Leadership Lancaster, where they help cultivate meaningful community connections, coordinate leadership programming, support alumni engagement, and create transformative experiences for emerging and established leaders across Lancaster County.
Beyond their professional work, Sage enthusiastically invests their time and energy into initiatives and organizations that align with their values and passions, with a particular focus on advocacy, equity, leadership development, and fostering inclusive spaces within the Lancaster community.
