John Shanahan is the owner of Lighthouse Window Cleaning in Rocklin, California. What began as a simple service business has grown into a mission-driven company focused on excellence, integrity, and care for people. John believes that how we work is a reflection of what we believe—showing up on time, working hard, and telling the truth are practical ways to live out faith every day.
