Zach started in a little CPA office in Chicopee, Massachusetts when he first graduated his undergrad. There he met his then soon-to-be business partner, Anthony R. Krusz. Together they moved to another building in Chicopee and started their own firm under the name, Anthony R. Krusz, CPA, P.C. After establishing himself, Zach became a shareholder in the company and they changed their name to Grzelak & Krusz, P.C. Soon, just the two of them became too big for that little office and they had to move once again. Zach and Ed then both decided to create Grzelak, Grzelak, & Associates, P.C. and make the two offices into one. Today the firm now operates in Holyoke, Massachusetts.
Zach graduated Westfield State College, in Westfield, Ma, with his Bachelor’s Degree in Business Management (concentrating in Accounting) and Economics.
He then went on to American International College, in Springfield, MA, earned his Master’s Degree in Accounting and Taxation.
Zach is a member of The American Institute of Certified Public Accountants (AICPA) and The Massachusetts Society of Certified Public Accountants (MSCPA).
