Garage doors rarely inspire passion, easily taken for granted as they dutifully trundle up and down to admit cars. People generally only notice them when they stop working, which is where David Miller and his father-in-law come in. They run EZ Lift Garage Doors, earning a living making sure that garage doors run smoothly and stay unnoticed. "I love running businesses, and my father-in-law has 20 years behind him in the garage-door-repair industry," David says. They continue to maintain, repair, and replace garage doors all across Houston while preserving the air of a family-run business.
