About
Most business owners didn't start their company because they love spreadsheets. They started it because they're good at what they do and somewhere along the way, the financial side became the part that keeps them up at night.
That's exactly where I come in.
I'm Devin O'Brien, CPA, CMA, and I've spent over 15 years working inside companies at every stage from early-stage startups to national brands like Loblaw and Bell Mobility. I've built finance functions from the ground up, managed teams across accounting and operations, and sat alongside founders and managing partners to help them understand what their numbers are actually telling them.
For the past three years, I've been running DVO Financial Consulting, bringing that same level of expertise directly to small business owners in Ontario. Whether you're trying to get a handle on cash flow, figure out the right business structure, stay on top of bookkeeping and compliance, or plan for real growth. I work with you to build a clear picture of where you are and a practical path to where you want to be.
What I've found is that most small business owners don't need more reports. They need someone who can read between the lines and tell them what to actually do. That's what I do.
Based in Guelph. Working with small business owners across Canada.
