A Personal Message from Eric Zielinski, CPA
Dear Client,
I hope this note finds you well. I’m writing today with big news and heartfelt gratitude.
After many fulfilling years in public accounting, I’ve decided to retire and begin a new chapter in my personal and volunteer life. As of July 1, 2025, I’ve officially transitioned the firm to Fortress Accounting, led by Peter Kihara and Javier Caceres.
I chose Fortress carefully. Peter and Javier share the same values that have guided my practice for decades—integrity, responsiveness, and genuine care for clients. They run a highly respected firm with offices in Connecticut and Florida, serving small businesses with accounting, tax, and consulting services.

I’ll continue working as a consultant during this transition, ensuring continuity and preserving your tax history. Kathy and Susan will also continue on with Fortress, so the full Z-Team remains available to support you.
Over the next few weeks, you’ll hear from me, Peter, and Javier directly. I’m confident you’ll be in great hands.
Thank you for the trust you’ve placed in us over the years. It’s been a true privilege to serve you.
Warmly,
Eric Zielinski, CPA
