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.

A lifelong entrepreneur, husband, and father, John strives to lead his business the same way he seeks to live his life: with humility, gratitude, and trust in Christ. He sees business not just as a means of income, but as a platform for service, stewardship, and community impact. John’s prayer is that his work would honor God, bless others, and shine light—one clear window at a time.
