Forty years, two generations, one standard.
Anthony Tenaglia, CPA, founded the practice in Wisconsin and has spent more than four decades in tax, accounting, and senior financial leadership. Colin Tenaglia joined a generation later, bringing a background in operations, risk management, and process improvement to the family practice.
The work has stayed the same: clear, honest counsel for individuals, families, and business owners — delivered by people whose name is on the door.

Why Tenaglia
A firm, deliberately not a product.
Experts in tax and accounting.
Forty years of CPA-led practice across corporate, partnership, trust, and individual taxation. The technical foundation is non-negotiable.
Planning, not just filing.
Tax, business activity, and long-term decisions are connected. We work the tax side of that broader picture so the right questions get asked — and the right specialists, when needed, are brought to the table.
A fiduciary, family standard.
Transparent, year-round counsel. We treat each engagement the way a family member would — not just an answer this April, but a client better equipped to decide for themselves over time.
Real people. Never a chatbot.
When you reach out, a partner answers. No phone tree, no AI receptionist, no ticket queue. Three offices anchor the practice in Wisconsin, Texas, and Colorado — but the firm serves clients nationwide.
Locations
