Stamford-based financial research company Greenwich Assoc. has awarded Citizens Bank a Greenwich Excellence Award for accuracy of operations in cash management.

For this year’s awards, Greenwich evaluated more than 600 banks and recognized 34 for “exceptional service quality.”

“Our number one goal is to provide our customers with a differentiated customer experience, so this recognition is especially gratifying because it reflects the feedback of our customers,” Chris Ward, president of Business Banking at Citizens, said in a statement. “Our bankers have great relationships with their clients. We work hard every day to bring them smart, fresh ideas that help them gain cash flow efficiencies that improve their bottom line.”
