About the firm

A firm built to show up before the deadline.

North Texas Advisors is a year-round tax, accounting, and advisory firm in Southlake, Texas — created to give owners and families a more proactive alternative to the traditional tax-season-only relationship.

Meet the founder

John Ornelas, CPA, CFE

FOUNDER & MANAGING PARTNER

John founded North Texas Advisors after building a career across public accounting, government tax enforcement, auditing, and private-sector finance and accounting leadership. His experience includes conducting tax audits for the Texas Comptroller's Office, serving with IRS Criminal Investigation, advising clients in public accounting, and leading finance functions within private businesses.

Having worked from multiple perspectives within the tax and financial landscape, John brings a practical, real-world approach to helping business owners navigate compliance requirements, improve financial visibility, minimize taxes, and make informed decisions that support long-term growth.

“You should not have to wait until tax season to find out whether the year went well.”

Why we exist

One brand, three connected services.

North Texas Advisors is the umbrella brand that brings together what were previously two separate service brands — North Texas Tax Advisors and Centennial Bookkeeping — into a single, coordinated relationship.

Advisory

Guidance for business decisions, entity structure, cash flow, profitability, owner compensation, and major financial moves.

Tax

Year-round tax planning, projections, preparation, and issue resolution so you can plan ahead instead of reacting later.

Accounting

Clean bookkeeping, reconciliations, reports, payroll and sales-tax support, and QuickBooks workflows that make the numbers reliable.
