About me

Rob practices exclusively in the area of taxation.  He represents clients in criminal and civil tax proceedings and provides tax planning advice to numerous business clients. Rob has tried many cases and negotiated settlements for clients involved in “Listed Transactions” deemed by the IRS to be abusive tax-shelter arrangements.
