Seth Hanenburg, CPA, Senior Manager

Seth, a senior manager in the Accounting and Outsourced Solutions department, joined Baker Holtz in June 2015 and transitioned to Maner Costerisan as of January 1, 2026. He currently oversees assurance and accounting solutions engagements for former Baker Holtz clients, working closely with businesses and organizations to support their financial reporting, compliance, and operational goals.

He values the meaningful relationships developed with colleagues, clients, and fellow professionals and approaches his work with a collaborative, service-oriented mindset.

Seth earned a Bachelor of Business Administration and a Master of Business Administration in Professional Accountancy from Davenport University. He lives in Byron Center, Michigan, with his wife, Jenn, their three sons, Dawson, Brady, and Flynn, and their two dogs, Lacie and Paisley.
