Founded in 1986, Grant Millman & Johnson PC has built its practice around assurance, tax, and employee benefit plan work in the Detroit metro area from its Novi, Michigan office.

The firm is a CPA practice that handles Assurance & Attestation engagements, Tax & Financial Planning, and Employee Benefit Plan Audits for organizations that need independent reporting and plan compliance support. Its audit work includes employee benefit plan audits, with services available for financial statement audits and related consulting needs.

CPA Shareholder Jeanne Jantzen is part of the leadership team and brings an independent perspective to client work, with a focus on process improvements and efficiency. The firm also supports owners and families with estate and trust taxation services alongside its core audit and tax offerings.

Compared with firms that only handle one side of the work, Grant Millman & Johnson PC combines employee benefit plan audits with broader assurance and tax planning under one roof, which can simplify coordination for clients.
