Former IRS-CI Special Agent · CPA, CFE
Robert Nordlander
For 20 years I was a special agent with IRS Criminal Investigation, following the money in tax evasion, fraud, and money laundering cases. Today my firm handles forensic accounting, expert witness work, and IRS tax resolution: settling back taxes, penalties, and collection problems. I also write, speak, and teach so professionals can see financial crime the way an investigator does.
