About Us
Good accounting is built on trust, and trust is built over time. This is a practice where clients come back year after year because their taxes get done thoroughly, their questions get answered plainly, and the person handling their finances actually keeps up with the constant changes in tax law. The work is personal — every return and every set of books gets careful attention, not a rubber stamp. If you've been looking for an accountant who treats your money like it matters, you're in the right place.
Based right here in Aurora — we answer the phone and show up when we say we will.
Clear quotes, no surprises. You know what it costs before we start.
We do the job right the first time and stand behind our work.

Love Marilyn for 30 years now. She's consistently helped me. Very thankful 🙏🏼
We have been with Marilyn for years. You have to trust the person that takes care of your finances and we do completely. I could not imagine going anywhere else. She is kind and caring and always goes above and beyond.
She is so thorough. I had made a mistake regarding my healthcare credit that would have cost me dearly. She does her research, keeps up on legislation, and was able to help me get a refund instead of a bill! She knows her stuff and will go far above and beyond for her clients.
Marilyn is more helpful and patient than I could have imagined. She is always upbeat and eager to answer any questions I have. She seems to really know what there is to know, which is a feat, since tax laws seem to always be changing. Marilyn makes the dreaded tax work — for both personal and business — bearable.
Good to know
Yes. That's the heart of the practice — one clear path for individuals and families, and another for small businesses. Whether you need a personal return, business books, or year-round advice, you'll get help suited to your situation.
The office is open Monday through Friday, 8:00 AM to 6:00 PM, and closed Saturday and Sunday. The best way to get started is to call (303) 337-6804 and schedule a consultation.
No. Accounting works best as a year-round relationship. Planning ahead, keeping your books current, and staying on top of tax-law changes throughout the year is what keeps April from becoming a scramble.
For individuals, bring your prior-year return and any income and deduction documents you've received. For businesses, bring your prior return along with your income and expense records. If you're not sure what applies, just ask when you call — we'll point you in the right direction.
