EDUCATION
Exceptional people surround themselves with the right people, bring enthusiasm every day, create their own reality, have laser like focus, and are patient with the process and results.
— Dr. Bob Rotella
Brett takes pride in what he does. Was achieving a 4.0 grade point average in college necessary? Was being selected as one of five Division III basketball players awarded first-team academic all-American a pre-requisite? How about doing that two years in a row? For Brett, it’s less about the accolades and more about the process, the hard work, and the growth. The accolades are the logical conclusion of unmatched discipline and grit.
The aforementioned 4.0 GPA was earned in pursuit of his Bachelor’s degrees in both Accounting and Finance at The College of St. Scholastica. Also, it was earned while completing three tax seasons as an intern at a large, multinational accounting firm. He later earned his CPA license from the state of Minnesota. Over the past decade, Brett has served small businesses and entrepreneurs in the areas of tax & accounting, spanning a number of industries including real estate, restaurants, and professional services to name a few.
In his free time, Brett can often be found out in nature either golfing or hunting (unless you’re the prey, in which case you’ll never see him). Occasionally, he finds some time to hang out with his very understanding wife. In all seriousness, he does very much enjoy spending quality time with her and travelling the world together.

BRETT TESTER, PRINCIPAL
After gaining extensive experience at a large public accounting firm and real estate investment company, I found myself wanting to support more small and medium sized businesses and their owners. When I discovered Dark Horse CPAs, I was instantly intrigued. The accounting industry often faces challenges in adapting to change and embracing a visionary approach.

Tax Strategy & Compliance for St. Paul Locals
The Problem: Many St. Paul residents only discover the sting of their tax situation at filing time—whether it’s an unexpected balance due, a smaller refund, or the realization they missed key tax-saving opportunities.

At Dark Horse CPAs, we believe in No Surprises. We work proactively with individuals and families throughout St. Paul to minimize tax liability, ensure compliance, and plan ahead. From state and federal tax strategy to retirement planning, real estate, and investment income, every engagement includes personalized advisory so you’re confident in your financial plan year-round.

The Problem: Too many St. Paul business owners operate without timely, accurate financial data—or without the strategic tax planning needed to protect profits.

Without proactive guidance, missed opportunities and costly surprises become the norm.
At Dark Horse CPAs, we combine bookkeeping, tax compliance, and forward-looking tax strategy for St. Paul businesses. From managing state and federal filings to providing cash flow insights, tax-smart planning, and Fractional CFO-level advisory, we give you the tools to make informed, growth-focused decisions.
