Joseph Brook

Vice President

I have been working with Greg since 2004 and have greatly benefited from his direction in the preparation of my personal tax returns. He has been equally helpful acting as a regular consultant to my many different and often unique tax situations and inquiries from my Wealth Management practice.

Our mutual clients have regularly mentioned Greg’s patient and accommodative approach that I have consistently experienced myself for decades.

I will continue to incorporate his tax advice for myself personally as well as professionally.
