GBQ Partners Auditor Profile

GBQ Partners is a professional services firm founded in Columbus, Ohio in 1953 by Morris W. Groner, later joined by partners Jack Boyle and Ron Quillin to form Groner, Boyle & Quillin. Grown both organically and through acquisition to roughly 360 associates, GBQ is the largest Columbus-owned accounting firm and a top-100 CPA and business advisory firm nationally.

Its assurance and risk advisory practices deliver SOC 1 and SOC 2 examinations along with IT general controls and broader risk advisory work, complementing services in tax, transaction advisory, valuation, and forensic accounting.

GBQ suits Midwest service organizations from growing SMBs to enterprise operations — especially in manufacturing, distribution, construction, real estate, and technology — that want SOC reporting from an established regional firm with deep controls and advisory capabilities.
