Crittenden began his career as a consultant at Bain and Company where he worked on various strategic projects in the United States and Germany. Crittenden served as CFO and executive Vice President at Melville Corp. While at Melville, he was the architect of the breakup of the company that led a significant increase in share price as the company was split into three firms. He was the CFO of Sears Roebuck and Company from 1997 to 1998. He then served as the CFO of Monsanto Company from 1998 to 2000. At Monsanto, Crittenden led the efforts to acquire seed companies DeKalb Genetics Corporation, and the Delta and Pine Land Company. He also played a key role in the eventual sale of Monsanto to Pharmacia & Upjohn. Prior to joining Citigroup, Crittenden was Executive Vice President and Chief Financial Officer of American Express, as well as the head of the company's Global Network Services division. In 2007, Crittenden joined Citigroup as CFO. At Citigroup, he led the reengineering effort that cut 75,000 jobs, reduced assets by around $500 billion, and helped guide the firm through the financial crisis. In 2010 Crittenden and the company settled claims of disclosure errors brought by the SEC, without admitting wrongdoing on the part of Crittenden, in connection with Citigroup's exposure to subprime mortgage assets. In April 2012, Crittenden was named CEO of Huntsman Gay Global Capital. In his first year at HGGC, Crittenden oversaw the sale of the utilities services holding company Power Holdings to Kelso & Co. for $380 million. Prior to Crittenden's arrival, Huntsman Gay Global Capital created Power Holdings by acquiring several utilities services throughout the United States. In just over two years, Power Holdings grew from approximately 90 utility crews to more than 200 crews. Crittenden and HGGC completed the sale via the $1.1 billion Huntsman Gay Capital Partners Fund I LP. In 2013, Crittenden became the chairman of Huntsman Gay Global Capital after co-founder Richard Lawson took over as chief executive. As chairman of HGCC, Crittenden oversaw the establishment of the firm's second vehicle, Fund II. Fund II will generally adhere to HGGC investment criteria such as revenues of $100 million or more, enterprise values of $100–500 million, and EBITDA of at least $15 million. In December 2013, Crittenden oversaw the acquisition of Lucent Polymers by the HGGC company Citadel Plastics Holdings, a top global thermoplastics and thermoset resins compounder. The acquisition gave Citadel Plastics access to a portfolio of over 1,400 formulations and enhanced its position in the engineered resins sector. Crittenden heralded the acquisition as a prime example of growth via strategic acquisition and integration of successful, complementary businesses. According to Crittenden, Citadel Plastics will benefit greatly from the financial strength and blue-chip customer base of Lucent, as well as its numerous development initiatives. The Lucent acquisition was Citadel's seventh since 2007 and the 31st overall acquisition for HGGC. Crittenden currently serves as the chairman of iQor, a global business process outsourcing services provider based in New York City. In January 2014, iQor acquired the aftermarket services business of Jabil Circuit, Inc. for $725 million. Headquartered in St. Petersburg, Florida, Jabil Aftermarket Services stands as the top aftermarket services provider in industries such as consumer devices, mobility, telecommunications, medical devices, and computing. The transaction boosts iQor revenues to over $1.5 billion and increases its employee count to more than 31,000 individuals across 16 countries. According to Crittenden, the acquisition helps iQor's customers benefit from a "considerably larger global footprint and additional financial resources." Crittenden has served on a number of corporate boards in his professional life, including Filene's Basement, where he was CFO early in his career, Wilson's Leather, Sears of Mexico and Sears Canada, Ryerson, Inc., TJX Companies, Staples, and Primerica. Additionally, he is chairman of the board of the HGGC portfolio companies: Power Holdings, iQor, and Citadel.
