A CPA firm built for long-term partnerships with businesses nationwide.
Schumacher Sama LLP has served businesses across the country since 1960. Our team focuses on long, trusted relationships — not transactional work.
We took over a firm that's been quietly doing right by Wisconsin business owners since 1960 — and we don't take that lightly.
Our job, the way we see it, isn't to file your taxes once a year. It's to sit on your side of the table all year long, ask the questions no one else is asking, and tell you the truth in plain English.
If that sounds like the kind of CPA relationship you've been missing, pick up the phone. We'd genuinely like to meet you.
We're a Wauwatosa-based CPA firm serving small and mid-sized businesses nationwide, from local companies in Milwaukee and Southeast Wisconsin to independent insurance agencies across the country.
We're more than accountants. We're long-term financial partners focused on clarity, confidence, and proactive strategy — so you stay ahead of tax deadlines, surprises, and big decisions.
Our team includes Certified Public Accountants, QuickBooks ProAdvisors, and seasoned advisors who have spent their careers serving business owners from coast to coast.
Calm, clear, and consistent — every quarter, every year.
