Costa Shepin, your tax advisor
One advisor. A continuing relationship.

You work with the person who knows your situation.

I built an independent practice to work directly with business owners and investors. My role is to bring technical depth, a practical point of view, and clear communication to the decisions you face.

I’m selective about the engagements I accept, with a focus on clients who value thoughtful planning and direct professional advice.
