American entrepreneur Andrew Lessman has an estimated net worth of $20 million. While he was in high school, he was fascinated with nutrition and vitamins. In his junior year, he designed his first science fair experiment about how vitamin use affected the health of his pet mice. He attended the University of Pennsylvania and graduated with a degree in biochemistry. He then went on to the University of Hawaii for medical school. He left medical school when he chose to shift his focus. He graduated from Loyola University Law School and began his career as a lawyer a few years later.

While Lessman was in law school, he trained for decathlon and began designed his own vitamin regimen. He also worked part-time for a vitamin company. In the late 80s, he decided to shift his focus from law to full-time vitamin development. In 1989, he founded his own company called ProCaps Laboratories. After more than a quarter of a century later, it remained as one of the few companies that manufactured the vitamins of uncompromised quality that they distribute. However, he was involved in a high-profile lawsuit in 2010 after he publicly criticized Home Shopping Network for carrying a particular brand of vitamin and yanked his own inventory from the network.`
