He has served as an outsourced chief financial officer of privately held companies and as a full-time CFO of two companies through their initial public offering, giving him a true sense of what it’s like inside a client’s operations.

Tom’s previous experience working in RSM’s audit practice as a consultant illuminated the firm’s need for a practice that specialized in both unique technical knowledge and consulting experience.
