Peter is an Associate with nearly three years of experience with experience across various sectors including financial services, industrials, telecom, software and energy.

At Accordion, Peter has a wide array of experiences working with Portfolio Companies throughout the Private Equity investment lifecycle.

During client engagement with established but underperforming companies, Peter has worked closely with CFO’s, Controllers and FP&A directors to optimize DSO through AR policy enhancements, developed Enterprise Strategic Planning Models for recently merged companies, and designed visibility dashboards to track enterprise KPI’s and optimize performance and determine business line profitability.
