Sean Cassidy


Sean Cassidy joined The Lighting Practice in 2019 after graduating from Thomas Jefferson University. He previously interned with a local lighting designer; it was in this role that Sean found a passion for using light as an artistic medium. Stemming from his interest in interiors and the built environment, he appreciates how lighting supports a mood and aids in the way people feel about a space. Since joining TLP, Sean’s experience has grown to include hospitality and healthcare environments. When he isn’t working, Sean enjoys indoor gardening and building functional ceramics.
