Meet Wendy

I treat your money like it's my own.

I started Windsor Accounting & Tax because I believe people deserve a CPA who actually knows them - not a 1-800 number and a different preparer every year. When you call here, you get me.

I sit down with you, ask the questions that matter, and explain things in plain English. My goal isn't just to file your return - it's to help you make smart decisions all year long, so tax time is the easy part.

Good questions

Things people ask before they call.

Do you work with both individuals and businesses? +
Both. I prepare personal returns for families and individuals, and I handle the full picture for small businesses - bookkeeping, payroll, entity setup, and advisory. Many of my clients are both: a business owner and a household.
Can we work together if I'm not in Windsor? +
Absolutely. I serve all of Northern Colorado, and plenty of clients prefer to handle things by phone, email, and secure document sharing. You're welcome at the office anytime, but you don't have to come in.
When should I start tax planning? +
The best time is well before tax season - ideally we talk during the year, while there's still time to make moves that lower your bill. That said, it's never too late to get organized. Reach out whenever; we'll start from where you are.
Do you help with QuickBooks? +
Yes - I offer QuickBooks setup, coaching, and ongoing help. Whether you want to keep your own books with confidence or hand them off entirely, I can set you up either way.
What is the Financial Life Roadmap Review? +
It's a sit-down session where we map your entire financial picture on a single page - income, taxes, debt, business, and goals. It gives you a clear, big-picture view and a plan for the year ahead. It's one of the most valuable things we do together.
How do I get started? +
Just call me at 970.829.8291 or send a note through the contact form. We'll set up a short conversation, figure out what you need, and go from there - no pressure, no obligation.
