Having first-chaired complex, mega-dollar and criminal disputes from coast-to-coast for almost 40 years at the very highest reaches of the tax profession …

Having represented the IRS during the first half of his tax career, and having represented a plethora of blue-chip corporate, non-profit, and individual taxpayers in the second half …

Having practiced for 18 years in Washington, D.C., and then 18 years in Chicago …

Having been a supervisor with the Tax Division of the U.S. Department of Justice (DOJ), and a partner or shareholder in the Chicago offices of two of the nation’s largest and most prestigious private law firms …

Having received many coveted, formal awards from his peers in both places …
