Our Story

Before establishing 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. With over 20 years of experience in the accounting field and as a controller, Timothy’s expertise provides results that save his clients time and money.
