After his arrival at UCSF, Kessler uncovered multiple spreadsheets for the same closed fiscal year (a year prior to his recruitment), all showing different revenue and expense numbers, but indicating that the dean's office was in deficit and would continue to be so, in direct contravention of what had been reported to him during his recruitment, evidence of, at best, inadequate financial controls. J. Michael Bishop, Chancellor of UCSF, claimed UC audits found no evidence of financial irregularities and, in June 2007, Bishop demanded Kessler's resignation. On December 13, 2007, Kessler was formally dismissed. Bishop then acknowledged that the financial data presented to Kessler during his recruitment might have been misleading. Kessler alleged he was fired for whistleblowing. Subsequent to Kessler's firing, after UCSF was pressured by KPMG to release one of the audits, it was revealed that Kessler had been correct.
