Mark A. Colella
CPA & Certified Tax Coach
New York, NY
Built for owners whose finances need coordination, not more paperwork.
Multiple businesses & entities
Several operating companies, a main business with real estate LLCs, or spouses who both own businesses. The pieces all need to work together.
Business + real estate & investments
A main operating company plus property LLCs or investments, each with its own tax picture.
Planned & year-round
Proactive, year-round tax planning, so a decision in one area is made with an eye on how it affects another.
Boutique by Design
I keep my client list intentionally focused so clients work directly with me.
“Hi, I'm Mark. When you hire Colella CPA, you work directly with me.”
I run a small practice on purpose. Keeping my client list short means I can answer your call myself, remember the details of your situation, and plan ahead with you throughout the year.
Some of my clients have worked with me for more than a decade. Those long relationships are why I keep the practice boutique. When I know your history, I can give you better advice about what comes next.
