According to his biography on The Little Couple's official site, Klein earned a degree in biology from NYU, meaning he and Arnold were originally looking to work in the same field. However, his career has focused predominantly on sales in the years since.
Klein has worked various high-profile senior-management gigs at companies that bank from $45 to $250 million in annual revenue, reportedly getting promoted wherever possible. The TLC stalwart also previously worked in Houston, consulting with clients independently in the areas of strategic direction, sales, and operational efficiency, as well as assisting start-ups. That work will no doubt continue in Florida.
