Maner Costerisan, a full-service public accounting and business advisory firm, is excited to announce the addition of three employees that grow the organization’s talent pool and client-based capabilities: Sarah Casby, recruiting and HR administrator; Jeff Allen, CPA, audit department senior manager; and Cole Williams, associate in the tax department.

“Sarah’s expertise in human resources and Cole’s addition to the tax department are valuable assets to our firm and clients. We’re also delighted to welcome back Jeff, who began his career with us over a decade ago,” said Jeffrey Stevens, president of Maner Costerisan. “We value relationships as the drivers of clients’ successes — that begins and ends with our own people.”

Allen, 33, was with Maner Costerisan for nine years before leaving to serve as a corporate controller for Centurion Medical Products. 

Previously at the Rush University Medical Center in Chicago, Casby, 33, has built a wealth of administrative experience since 2006. She received her MBA from Madonna University and her bachelor’s degree from Central Michigan University. 

Williams, 25, begins his career in Maner Costerisan’s tax department as an associate. Formerly with Fifth Third Bank, he graduated from Grand Valley State University in 2017 with a master’s degree in accounting and completed his undergraduate studies at Michigan State University.
