Zack Skrzyniarz, CPA, Principal

Zack is a principal in the Audit department, overseeing Maner Costerisan’s Telecommunications and Employee Benefit Plan (EBP) teams. With more than 15 years of experience, he specializes in providing audit, accounting, tax, and consulting support to clients, helping them achieve their financial goals and long-term visions. Additionally, he leads the collective teams’ strategic planning efforts, focusing on enhancing capabilities to better serve EBP and telecom clients across the Great Lakes region.

Driven by a passion for helping clients solve their problems – no matter how complex they may be – Zack enjoys continuously learning and enhancing his skill sets and those of his team. Seeing clients achieve success and knowing he was a part of helping them get there is what motivates him to be better each day.

Determined, friendly and approachable, one of the favorite parts about Zack’s job is the opportunity to meet new people and learn about their companies and unique needs. He’s able to take something from every client he works with and use insights from previous experiences to improve.

A resident of Dewitt, Michigan, Zack loves spending time with his wife, Beka, and their three boys, Logan, Parker, and Miles. In his free time, he also enjoys golfing, watching movies and TV shows (particularly the Superhero genre) and listening to and discovering new music.

The people I get to work with every day are what keep me at Maner. We have amazing professionals and people that feel like a big family.
