What we Do

Your trusted advisor and problem solver.

Full service accounting and tax practice

We formed Whalen Professional Corporation in 2010 with the goal of creating an accounting practice that was purpose driven and useful to its clients.  Accomplishing this by maintaining the small size of the firm and focusing on client relationships, high quality work, efficient turnaround times, and standardizing the annual filing requirements into a streamlined system.  This leaves more time to deal with the bigger picture issues, lowers the level of stress for clients and staff alike, and creates an environment of collaboration and open communication with clients, while getting done what needs to be done.

We pride ourselves on our practical advice and friendly service. Our goal is to help our clients achieve their full potential by providing the financial expertise they need.​

We are actively involved in the local community and can coordinate with your lawyer, banker, financial planner, and insurance agent to make sure you’re making the most of your business, and planning well for your future.

We provide a full range of services to support your business, we will work with you to determine which services you need. We encourage our clients to pick and choose the services they need based on the point they are at in their business. Your needs will change over the years and we want to add value where we can, not sell you services you don’t need.
