Program Coordinator

Mannie is a lifelong resident of Lancaster, having spent his formative years in Lancaster City. Growing up in this vibrant urban environment, Mannie had the privilege of being exposed to a rich tapestry of people, cultures, and diverse perspectives.
At the age of 13, Mannie’s family relocated to East Petersburg, marking the beginning of his journey as a student in the Hempfield School District. The transition to this markedly different educational environment provided Mannie with a valuable opportunity to engage with a wide range of voices and viewpoints, broadening his horizons beyond his city upbringing.
In 2019, Mannie proudly graduated from Hempfield High School and continued his academic pursuits at Thaddeus Stevens College of Technology. Throughout his time at Thaddeus Stevens, Mannie was an active and engaged student. He served as the Vice-President of the Student Government, where he managed various responsibilities, including event planning, collaborative teamwork, and budgeting. His dedication and leadership earned him the honor of delivering a commencement speech at the 2022 TSCT graduation.
Mannie is also a graduate of the 2022 Thaddeus Stevens College Core Class. His participation in Leadership Lancaster Programming offered him a fresh perspective on his hometown, igniting a passionate commitment to contributing to the ongoing efforts to enhance the quality of life in Lancaster County.
When he’s not at his desk, Mannie enthusiastically invests his time and energy in organizations aligned with his interests and values. Currently, he serves as the Vice President on the Board of Directors for Lancaster Pride
Mannie proudly calls Lancaster City his home, sharing it with his cherished pets, Syrax, Solstice, and Verm a band of bearded dragons.
