Aaron Johnson


Aaron draws on his extensive experience developing and validating models for pre-provision net revenue, stress testing, and consumer credit scoring to help Promontory clients manage risk.


He previously led validation of PPNR models at PNC and was a specialist in data analysis for the Public Company Accounting Oversight Board’s Center for Economic Analysis. During his earlier tenure at Promontory, Aaron developed and validated a variety of statistical models used in stress testing, provided analytical support for a large independent foreclosure engagement, served as a technical writer, and helped manage engagements in the quantitative group. Prior to that, he was a statistical analyst for TransUnion’s custom modeling group, where he developed consumer credit-default models for domestic and international clients, including credit unions, banks, and personal-finance companies. In this role, Aaron also validated statistical models, acquired a deep understanding of consumer credit data, audited the implementation of scoring models, and provided other custom analytics. Before TransUnion, Aaron developed databases for the University of Illinois at Chicago and implemented other initiatives that streamlined administrative functions.
