Cascade CPA closed its office on Monday, September 7, 2026, in observance of Labor Day.

You have outgrown spreadsheets and part-time help. That does not mean you need a full finance department, just the right partner. We do accounting differently. Accounting should accelerate your progress, not slow you down. Our model focuses on responsiveness, proactive guidance, and meaningful relationships. After listening to nonprofits and small businesses, we built our approach around what matters most: quick answers, timely work, proactive advice, and a long-term relationship with the accountant who actually knows your business. Cascade CPA delivers outsourced accounting and tax strategy with CFO-level insight without the overhead. From Client Accounting Services to Core Accounting Support including tax planning, controllership, financial reporting, and bookkeeping, we provide the insight and confidence growing organizations depend on. Our specialized teams bring deep expertise across industries including nonprofits, insurance, HOAs, restaurants, manufacturing, and professional services. At Cascade, numbers are only part of the story. Relationships are what keep them meaningful. Our Story: Our company roots go back to 2007, when Julie Miller and Mike Kollath merged their practices to form Kollath & Associates CPA. The firm grew quickly across Wisconsin with three offices and clients nationwide. In 2025, we rebranded to Cascade CPA to reflect who we have become and where we are headed, while carrying forward the trusted reputation built under the Kollath name.
