Shirley Tom, Managing Principal


Born in Montreal, Shirley has been engaged in public accounting and various finance sectors since the mid-1970s, including a long term stint at a Bay Street law firm in the estates and trust practice area. Since setting up the practice in 2005, helping entrepreneurs achieve their dreams is at the forefront of Shirley’s business motto “Vision Beyond Numbers”.  She has more than 25 years of extensive experience in all facets of accounting, tax and consulting work with a marketing flair in keeping with the fast paced changing technologies of our times. With a strong understanding of corporate governance issues, Shirley also offers business advisory services for structural changes and management processes in corporations and not-for-profit entities. She readily understands the commitments and hard work required for building business value and will go the extra miles to achieve results for her clients.

Shirley received her Certified General Accountant designation in 1989 and, in addition to her 2004 Ontario Distinguished Service Award, the prestigious FCGA award from CGA Canada in 2011 and her FCPA in 2015. She completed the rigorous program for her Chartered Director designation in 2012. Shirley is also a Certified Executor Advisor (CEA) since 2016. Shirley believes in giving back to the community and currently serves on many non-for-profit boards and executive committees.

Victoria Grigg, Senior Associate

Victoria obtained her Bachelor of Business Administration at Wilfrid Laurier University in 2009 and earned her Chartered Accountant (CA) designation in 2012 with PricewaterhouseCoopers (PwC) honing her public accounting knowledge during her 4+ years with the firm.  Since leaving PwC, she expanded her knowledge of the wholesale, retail and banking industries through her work in Internal Audit at The Beer Store, Loblaw and PC Financial (a division of Loblaw).  Her previous experience includes both financial and operational audits, where she assisted businesses in identifying efficiencies in order to help drive company success.  I am confident her competencies and capabilities will be a great asset to this firm and, in turn, your business!
