About Us

Meet Brian O'Toole, the esteemed Founder, President, and CEO of Number Nexus. With an established background spanning over a decade at a regional accounting firm, Brian developed a genuine passion for supporting small and medium-sized businesses, as well as individuals who often went unnoticed by traditional accounting firms. His aim was to revitalize the personalized experience clients have with their CPA, and thus, he took the bold step of launching Number Nexus.

Originally from the outskirts of Chicago, Illinois, Brian pursued higher education at Elmhurst University, culminating in his graduation in 2012. Soon thereafter, he successfully passed his CPA exam, solidifying his expertise in the field. When Brian isn't immersed in accounting, you might find him exploring the remarkable museums and zoos that Chicago offers, spending quality time traveling with his family, or gracefully swinging a club on the golf course.
