Portrait of Businessman

Nathan Tierney, BBA
Staff Accountant

Daniel's accounting path began in 2006 when he was hired as a Junior Accountant at a respected, regional public accounting firm in Waterloo. Thanks to his mentors and over eight years at the firm, he gained experience in accounting, bookkeeping, financial statement preparing, and tax preparing. 

Outside of the office, Daniel enjoys activities with his wife, Lin, and three children. Music is also a part of his life and plays the Scottish smallpipes as well as the Great Highland bagpipes. If requested, he will be more than happy to play a tune for you! 

Nathan joined DC Accounting in January 2023 and is our very own CPA aspiring student. He achieved his BBA (major in accounting) and his background includes over five years with a variety of work in bookkeeping, tax preparation, IT/IS, and accounting software.

Legend has it that when Nathan goes back home at the end of the day, he enjoys building model historical battlefields where he can strategize alternative outcomes to famous events.

Cassie Wettig
Assistant Manager

Lin Cockburn
Firm Administrator

Cassie joined the firm in March 2023 right in the heart of tax season and it didn't take long for her to progress to Assistant Manager. Her hard work, enthusiasm, and organizational skills couldn't be overlooked so we had to make good use of her talents.

When Cassie is not in the office, she can be seen perfecting and working on her latest baking recipes. You may even see her at the St. Jacobs Farmer's Market where she sells some tasty treats.

Lin brings her background of customer service and administration skills to DC Accounting.

During her spare time, Lin enjoys creating plant-based meals and working out.
