Conrad Prebys moved from South Bend at age 32. He’d grown up in a big family with a small income. His father was a tool-and-die maker and the family that crowded into the small house included his parents, four brothers, his grandmother and an uncle.

At age 7, Prebys had his first medical run-in when he stepped on a belt buckle and was bedridden for a year with an infection that affected his heart. He recovered and went on to college, worked as a mid-level manager at a steel company — he still looks pained recalling being forced, at age 24, to lay off men twice his age — before leaving to run a pizzeria with his brothers.

He came with little money to San Diego to visit a brother, then decided to stay. Here was a beautiful place “where I could make a buck,” he recalled.

He got a job selling $6,990 starter homes. A year later, he and partner Tom Sparrow founded Progress Construction. In 1979, he bought out Sparrow.
