About the firm
Quillmont CPA opened in 2009 in a fourth-floor office on Riverside Avenue, a few blocks from the river. We work for families, the self-employed and small businesses: contractors, shops, clinics, restaurants and the people who own them.
How we are different
Every client has one accountant who knows their file from year to year. Fees are fixed and agreed in writing before the work starts. And nothing is filed until we have gone through it with you, so you know what you are signing.
Online or in person
Most of our clients never need to visit: documents go through our secure portal and meetings happen by phone or video. When you would rather sit across a desk, the office is downtown, with parking in the garage next door.
What we stand by
Plain words
We explain what a return says and why, without jargon.
A price first
A fixed fee in writing before any work begins.
Your data, guarded
Encrypted portal, signed authorizations, and nothing sent by plain email.
