Adam Diekelman

As CFO of Castle Credit Co Holdings, LLC and Great American Finance Holdings, LLC, B-to-B and B-to-C financing firms located in Chicago, Adam Diekelman leads the firm with the kind of wisdom and insight that can only come from a career that includes a five-time tenure in the role, all in consumer specialty finance. He’s worked with a multitude of omni-channel sectors, in a capacity backed by venture capital, private equity, private funds, and public entities on the stock exchange. Add to that his strong background in fraud mitigation and knowledge as a member of the Association of Certified Fraud Examiners (ACFE), and there is no more powerful combination for a leader in a private equity role. Castle Credit and Great American Finance are consumer specialty financing firms with a focus on retail sectors, including furniture, auto, pets, big box retailers, and more, as well as home improvement financing, with loans ranging from $2,000 to $50,000.


In his role, Adam serves as the CFO of Castle Credit and Great American Finance’s four distinct divisions: retail consumer, home improvement, leasing, and servicing. Adam’s success lies in his versatility and flexibility, and his ability to see challenges from other perspectives as well, having overseen myriad divisions in his career. While maintaining the classic numbers-driven approach of a CFO, he’s also able to take on the organizational and interpersonal roles of a CEO. However, he also credits his rise to the excellent mentors he’s had along the way and to sheer hard work. “I always outwork my competition,” he says. “I’m willing to go the extra mile and this has always put me ahead.”


After getting his master’s degree at the University of Wisconsin Whitewater, Adam was faced with the economic recession, and worked a number of jobs before landing an accounting role in Chicago. From there, his natural talent for business and drive to succeed fast-tracked him into C-level roles—and he never looked back. He also credits his acumen for numbers and data to his parents, both teachers in Spanish and mathematics, whom he lost at an early age—an experience that drives him to ensure stability for his own family. “I’m building that solidified foundation, an empire, for those who are still to come into my life, and so I can enjoy my life with my loved ones.” To that end, Adam’s ultimate goal is to become an executive in the Fortune 500 role, keeping in mind his motto that has already gotten him so far: “If you’re persistent, you’ll get it, and if you’re consistent, you’ll keep it.”
