My Story
I've spent the better part of 30 years making complex systems run reliably — first in the world of technology, now in the world of small business bookkeeping — serving home service businesses across the Fox Valley.
Not long ago, I sat down to catch up on my own books. I'm a bookkeeper — and I still felt that sense of dread looking at a backlog of uncategorized transactions, taunting me. I knew exactly what needed to be done, but the moment was still uncomfortable.
I can only imagine how that same situation feels for you.
That experience is exactly why I do this work the way I do. No shortcuts. No "good enough." Every transaction categorized correctly. Every account reconciled. I make sure every number is not just right — but understood.
When you entrust me with your books, you're not getting a pool of strangers rotating in and out. You're getting one person. One person who knows your business and local area, who shows up consistently, and who treats your finances with the same care and scrutiny I apply to my own.
Because the day I stop doing that is the day I stop doing this.
Why Home Service
I built this practice for home service businesses on purpose. You're exceptional at your trade and buried in the business side of it. You didn't start this business to reconcile bank accounts at 10pm on a Sunday. That part is my job — and I'm good at it.
Home service owners respond to straight answers, not jargon. So that's how I work. I tell you what your numbers mean in plain English, and I tell you the truth even when it isn't the easy thing to say.
How I Work
Every client gets a set day on my calendar, every week — not squeezed in when there's time. Your statements are ready by the same date every month, and I walk you through what they mean before you ever have to ask.
Setup is done once, and done right — before any work starts, not scrambled together after. And I check back in after your first month, because getting it running isn't the same as knowing it's working.
You're not a file in a queue. You're a person I actually know.
Certified. Qualified. Ready to help.
