Alan P. Stokes, CPA, RFC, President

Alan Stokes, owner of Century Accounting & Financial Services, has been a small business owner himself for over 32 years. He appreciates the stress and hard work it takes to grow a successful small business. Alan’s passion and expertise (along with his team) is helping his clients make the everyday decisions that affect the success of their business. His CPA designation requires him to stay up to date on the ever-changing tax and accounting regulations by taking the mandated Continuing Education courses, in addition to keeping his financial services and insurance licenses up to date. 

When asked “What do you enjoy most about working with small business clients?”, his answer is, “It's very satisfying to not just look at a page with numbers on it, but truly interact with the clients in helping them make sense of how it all affects their business, good and bad.”  Since starting the firm, his expertise has grown over the years, working with hundreds of small business clients, non-profit organizations and individuals in both an advisory capacity and hands on, helping new businesses get up and running properly, and getting clients’ records current. A key part of his practice is also tax planning and tax preparation.
