Today, Maner Costerisan announced it has named Jeffrey P. Allen a partner in the firm. Allen has worked for 11 years for the Lansing-based accounting firm in the audit, accounting and outsourced solutions departments.

Allen said his recent promotion and rewarding career at Maner Costerisan came from a chance job shadow when he was 16 years old and exploring possible career paths and weighing the decision to go into finance or accounting. Allen’s father knew an engineer at Parker Hannifin Corp. who arranged the job shadow with a plant controller, and Allen said the job shadow laid the foundation for his current career.

“The controller convinced me that accounting was a language and that I could always go into finance with an accounting degree, but I couldn’t go into accounting with a finance degree,” he said.

Now 33, Allen has grown his career working with Maner Costerisan’s certified public accountants and business and technology advisors. He conducts affordable housing audits and specializes in providing outsourced chief financial officer and controller services to businesses, governments and not-for-profit organizations. In addition, Allen provides valuation expertise and abilities to closely held businesses looking to buy, sell or gift ownership.

Allen began working at Maner Costerisan in January 2006 after his graduation from Western Michigan University. He left the firm for a few years to work for a client of the firm as a controller. Allen said the move allowed him the opportunity to adopt new skills and gain a more in-depth understanding of “the other side” of the client experience. He eventually brought his insights back to Maner Costerisan when he rejoined the firm in January 2018. He said using that acquired insight to solve unique client problems is the best part of his job at Maner Costerisan.

“We use data to answer questions and predict outcomes,” he said. “Answering the questions that seemed impossible at one time to answer and tackling something that’s never been tackled before and figuring it out — it’s all very rewarding and a chance to constantly grow.”

Allen is a member of the Michigan Association of Certified Public Accountants and the American Institute of Certified Public Accountants. He has given presentations for the MICPA as well as the Maner Solutions Conference. He and his wife live in Grand Ledge with their two sons. In his free time, Allen enjoys backpacking and world travel, and his journeys have included whitewater rafting in the Zambezi River near Victoria Falls in Africa.
