Jim Sherman, Advocate’s Founder and CEO, has been a CPA for more than 20 years. Graduated with honors from Northern Illinois University, Jim began his accounting career at Centel Corporation, a Fortune 500 telecommunications organization. After eight years there in positions of increasing responsibility, he left for a $3.5 billion division of Sprint Corporation, first as assistant treasurer and then acting treasurer, becoming a leading contributor to a $50 million cost savings project.

In 1996, the Chief Financial Officer position lured him to a $90 million independent national transportation and distribution company. By renegotiating corporate debt and slashing expenses, he not only helped save the company from bankruptcy, but turned a deficit of $4 million to a profit of $2 million in two years, positioning the company for sale.

Then Jim spent six years at Mitsubishi Corporation, a $300 billion conglomerate, as Chief Financial Officer of a $250 million division, before taking the entrepreneurial leap of founding Advocate. His vision: to bring mid-sized and emerging businesses the same strategic insight, financial methods, and economies of scale from shared resources that characterize big business in America.

Following the advice he gives clients, Jim concentrates on counseling, tax planning, and financial analysis for Advocate’s clients.
