About Brien’s Business Umbrella Accounting

Your Trusted, Experienced Advisor

Before Brien’s Business Umbrella Accounting, Timothy Brien prepared individual tax returns and worked as a full-time Controller at a Unionized Manufacturing Plant. After his decision to seek opportunity elsewhere by exploring newer technologies, Timothy founded Brien’s Business Umbrella in 2016. His experience of over 17 years in the Accounting field and as a Controller grants Timothy the ability to provide accurate and efficient results that saves his partner’s time, money, and relieves their stress.

With every service that Timothy offers, he incorporates innovative, non-traditional solutions to deliver a superior product and customer service experience to each client. His close attention to detail, coupled with his knowledge, use, and incorporation of modern technologies creates an efficient, accurate virtual workplace to collaborate and receive input from his valued partners. 

Timothy learns the struggles and challenges that each of his partners experience with their current Accounting or Payroll methods. He then implements his own customized solution specific to their needs. Located in Buffalo, NY, Timothy’s virtual firm enables him to do what he loves, so businesses throughout the U.S. can continue doing what they love to do!

Tim always checks in to make sure everything is going smooth and if I have any questions. If you need help navigating through/ learning QB I would highly recommend getting in touch with him!"
