Founder, Senior Partner

Gregg’s primary focus is on financial and retirement planning for families. He builds a close working relationship with his clients to understand their investment, insurance, and estate planning needs and then partners with them to develop a thorough financial plan. Once the plan has been implemented, the relationship is fostered by a high level of service to ensure the plan continues to meet the family’s changing needs. Gregg proactively reaches out to his clients on a consistent basis through meetings, phone calls, and e-mails so that they can be confident that their situation is being closely monitored. Gregg has significant experience working with both current and former Xerox employees. With his extensive knowledge of the Xerox benefits system, he can help families get on the right track long before they retire and make the transition into retirement virtually seamless from a financial point of view.

Gregg graduated from Clarkson University in 1987 with a degree in computer science and received his MBA in finance from the Simon School at the University of Rochester in 1992. He founded Marathon Financial in 2004 after 4 years at McDonald Financial and 13 years at Xerox.
