History | Philosophy | Service Team | Community Action |

We have over 25 years of experience providing first-class Accounting & Technology services to businesses in Mississauga, Toronto and the GTA.

The Mississauga accounting firm was founded as Sidler & Company in 1987 by
John Sidler, Richard Clarke and shortly after, Cathy Campbell. The firm’s first office
was located in Streetsville in the basement of a former home located on Queen
Street South. The firm moved to its existing 6465 Millcreek Drive location in 1990
and has increased its second floor footprint five times to accommodate the growing
ranks of its client service team.

The firm was founded with core values that persist today: client focus, trust, team
work, excellence and social responsibility. The firm is led today by Client Service
Partners that have developed through its ranks, many of them progressing from
accounting student positions with the firm to Client Service Managers and leading
onto Client Service Partners. Cathy Campbell left to pursue a career closer to home
in 1995. Annette Silva, Curtis Link, Jason O’Halloran and Kalin McDonald were
promoted to partner in January 2000. John Sidler retired in 2005 to pursue other
business interests. Greg Rawn was promoted to partner in 2009, and Paul Keul was
promoted to partner in 2011.

The firm mourned the loss of Annette Silva when she passed away in September

All of the partners are specialists in their field and have earned important
professional designations, which include Chartered Accountant, Chartered Business
Valuator, Trust & Estate Practitioner and Certified Financial Planner.
