Biography
Education: Michigan State University, Wayne State University Law School
Dan Gilbert was born in a Detroit suburb on Jan. 17, 1962, the son of a bar owner. He studied at Michigan State University and completed his law degree at Wayne State University. He delivered pizzas and used his earnings to set up lender Rock Financial in 1985, according to the company’s 1998 prospectus. A year later he started Rockloans.com, an online direct mortgage lender.
Rock Financial was bought by software maker Intuit for $370 million in 1999, and was renamed Quicken Loans. Three years later, Gilbert bought back the company, which thrived following Lehman Brothers’ collapse in 2008, having avoided entering the subprime mortgage market. The billionaire moved the company’s headquarters to downtown Detroit in August 2010, and through closely held investment company Rock Ventures started to buy buildings in the city center.
Gilbert took the company public again in August 2020 as Rocket Companies, Inc. At the time of the IPO, the company had a valuation of about $35 billion and was the country’s largest retail mortgage originator.
Gilbert, who bought a 72 percent stake in NBA franchise Cleveland Cavaliers in 2005, has also expanded into casinos, buying Detroit’s Greektown Casino in April 2013. He also owns Rock Ohio Caesars, which owns resorts and racetracks in Ohio and Kentucky.
The billionaire lives on the outskirts of Detroit and has five children with wife Jennifer. He attracted national attention with a letter accusing departing Cavaliers player LeBron James of betrayal in 2010. The pair reconciled in July 2014, with James returning to Cleveland for the 2014/2015 season.
Gilbert was hospitalized after suffering a stroke in May 2019.
Sports franchise ownership
In 2005, Dan Gilbert bought the Cleveland Cavaliers for $375 million, which was then a record price for an NBA team. Since then, he has overseen significant improvements to the team’s facilities and helped bring in top players like LeBron James.
In 2006, Gilbert also purchased the Cleveland Monsters, a professional ice hockey team in the American Hockey League. The team is affiliated with the NHL‘s Columbus Blue Jackets.
Gilbert has been an active and vocal owner, often speaking out on social media and in public about his teams and the NBA. He has also been involved in efforts to bring major sporting events to Cleveland, including the NBA All-Star Game and the NFL Draft.
Gilbert’s ownership of the Cavaliers has been marked by both success and controversy. The team won its first NBA championship in 2016, but also went through a tumultuous period after LeBron James left in 2018. Additionally, Gilbert has faced criticism for his treatment of former head coach David Blatt and for his aggressive pursuit of tax incentives and public funding for his various business ventures in Cleveland.
Overall, however, Dan Gilbert’s ownership of the Cleveland Cavaliers and the Cleveland Monsters has been a significant part of his business and investment portfolio, and he remains a prominent figure in both the NBA and the city of Cleveland.
