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 AND MANAGING PARTNER

John founded North Texas Advisors to bring tax, accounting, and advisory work together under one relationship — so clients get clean numbers, a clear tax picture, and practical guidance throughout the year, not just at filing time.

His background spans public accounting, private-sector tax leadership, and prior experience with IRS Criminal Investigation — along with business advisory, tax planning, bookkeeping, and firm-building. That mix shapes how the firm works: technically rigorous on the details, and plain-spoken about what they mean for your decisions.

“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.
