However, Singer was also the mastermind of a scheme that saw 33 parents of college applicants accused of paying him more than $25 million [£17,998,875] between 2011 and 2018.
Singer would use part of the money to fraudulently inflate entrance exam test scores and bribe college officials to secure college places for applicants. There were mainly two ways Singer carried out his scheme – by cheating on college entrance exams, including SAT or ACT and fabricating sports credentials.
Among the accused are prominent business-people and actors, including Felicity Huffman, Lori Loughlin, Mossimo Giannulli, Gamal Aziz and Bill McGlashan.
He controlled the two firms involved in the scheme, Key Worldwide Foundation and The Edge College & Career Network, also known as the Key.
In 2019, he pleaded guilty and worked with the FBI, helping them to gather evidence against several co-conspirators.
NBC reported Singer admitted to police he had unethically facilitated college admissions for children in more than 700 families.
