CHRISTIAN ONYEMEM

CEPA (Certified Exit Planning Advisor) — Exit Planning Institute, 2026

CPA (Certified Public Accountant)

CFE (Certified Fraud Examiner) — brings a forensic lens to every engagement, a differentiator most audit and due diligence providers don't carry

Founder & Managing Partner, CO CPA Firm, PLLC — built a Houston-based firm with a distributed international team spanning accounting, tax, attest, and advisory

Master of Science in Accounting

10+ years of accounting experience, including Big Four training and background

Built and led the firm's Quality of Earnings (QoE) practice — developed the full delivery infrastructure (service delivery guide, SOPs, working papers, planning memos, client templates) to serve lower middle market M&A transactions

Led the firm's attest department buildout — audits, reviews, and compilations, including GAAS financial statement audits for government-contracted nonprofits

Uncovered material financial misstatements in live due diligence work, including a GL analysis that surfaced tens of millions in overstated balances driven by a broken reconciliation process — work that reshaped the deal structure for the client

Built the firm's Virtual CFO and Client Accounting Services practice, giving clients a full-service financial backbone from bookkeeping through the C-suite

Began his accounting journey at age 13, helping his father manage business finances — a foundation that grew into a full-service CPA firm

Christian Onyemem, CPA, CFE, CEPA, is the Managing Partner of CO CPA Firm, PLLC, a Houston-based accounting and advisory firm serving business owners, private equity buyers, and lenders across the country. Christian's lane is clear: he is the CPA business owners and dealmakers call when the numbers need to hold up under scrutiny.

With over a decade of accounting experience — including a Big Four background, a Master of Science in Accounting, and the Certified Fraud Examiner (CFE) credential — Christian built his practice around a simple premise: financial statements should tell the truth, and due diligence should find out fast if they don't. He leads CO CPA Firm's attest department, overseeing audits, reviews, and compilations, and he built the firm's Quality of Earnings (QoE) practice from the ground up to serve the lower middle market — the deal size range too often underserved by traditional due diligence providers.

His work has uncovered material misstatements that changed deal terms before closing, and his forensic training as a CFE means he's not just checking the math — he's looking for what the math is hiding. In 2026, Christian added the CEPA (Certified Exit Planning Advisor) credential from the Exit Planning Institute to his credentials, deepening his ability to guide business owners through the full arc of a transaction — from getting the business exit-ready to standing behind the numbers once a buyer is at the table.

Christian's path into accounting started early — at age 13, helping his father manage the finances of a family business. That hands-on start shaped a career built on rigor, skepticism, and a refusal to take numbers at face value. Today, he leads a distributed international team delivering CFO advisory, client accounting services, tax, attest, and M&A transaction advisory — but the work he's most known for is the work that happens when a deal is on the line and someone needs to know, with certainty, what the numbers actually say.
