Preston Lewellen is a Senior Director with Alvarez & Marsal (A&M) Corporate Performance Improvement in New York, with over a decade of experience in finance focused on banking, payments, capital markets, treasury, corporate strategy, mergers and acquisitions and executive management advisory services.

Since joining A&M, he has led in key account development initiatives and in the mentorship of junior staff. He has executed large scale enterprise-wide transformation through M&A, carveouts and divestiture programs, as well as served as lead PM for major company-wide implementation projects while providing subject matter expertise for payments and business continuity engagements.

As part of a $75 billion merger of two global industrial gas companies, Mr. Lewellen advised in the carve-out of four businesses concurrently and to the stand-up of the divested North American business. In this role, he separated and re-established customer and supplier agreements, IT infrastructure and business applications, plant and distribution assets, permits, corporate functions and organization sizing and selection, finance, corporate communications, and re-branding. Mr. Lewellen also developed transition service agreements and product supply agreements, as well as led the Project Management Office (PMO) to advise the North America management team.

Through the restructuring of an independent power producer with generation facilities across the U.S., Mr. Lewellen led the stand-up of the risk, regulatory and legal functions.  At a top five global investment bank, he led the PMO for three firm-wide regulatory compliance implementation programs including every major product area, primary business hubs and main functional support units.  He has also provided subject matter expertise for card acceptance cost reductions and a go-forward negotiation strategy with payment processors for a Fortune 50 retailer, as well as established a framework of essential functions for an effective business continuity program for a Systemically Important Financial Market Utility (“SIFMU”).

Prior to A&M, Mr. Lewellen held key roles in financial analyses, strategy, mergers & acquisitions and program management for Citigroup, specifically Citi Holdings and its Corporate M&A divisions. Previously, he was the top-ranked performer of both Citi’s Financial Management Associate (“FMA”) and Financial Analyst (“FA”) programs.

He earned a bachelor’s degree in economics at the Wharton School of the University of Pennsylvania with concentrations in finance and real estate.
