Marty Griffith has been a critical driver to much of the commercial loan growth success of CNB Bank, especially over recent years where he was more involved in our entire corporate footprint. As our new Chief Revenue Officer, we look to extend his commercial banking success to promote the revenue generation collaboration among our key business segments. While continuing to support further qualitative commercial loan growth and increased top-line loan interest income across all our markets, we look for Marty and his team to identify opportunities to realize stronger revenue growth in our wealth and treasury management fee-based businesses.

Rich Greslick has been a key player in the development of the Bank’s operations platforms over the past twenty years when the Bank experienced a period of rapid growth. As Rich and his team have ensured that our company embraces the modernization and expansion of our support functions, he will now be charged with overseeing how these back-office functions, in conjunction with our Employee Resources objectives, can be further integrated to maximize the efficiency of the processes supporting our continued growth and franchise expansion activities.

Michael Noah has successfully led the growth of our BankOnBuffalo division in recent years, reflecting a combination of highly productive commercial business development officers, successful retail banking and funding efforts, integration of all aspects of treasury management, and successful cross-referral and development with the private banking and wealth management functions. As our new Chief Operating Officer, we look forward to benefitting from Mike’s leadership and skills in collaborating with our other Regional Presidents to best implement our corporate revenue generation and expense management initiatives, to realize more consistent efficiency and increasing profitability across all our divisions.”
