Pinnacle combines tax expertise, secure technology, and clear client service from our Peoria, Arizona office.

The practice is led by Gurjit Singh, EA, an Enrolled Agent authorized to represent taxpayers before the IRS.
Our service model combines professional tax preparation with secure document exchange, structured workflows, and straightforward communication. The goal is to make the client experience efficient without losing the judgment and guidance that tax matters often require.

Retirees, families, self-employed taxpayers, owner-operators and small business owners across the West Valley — the same careful, plain-language approach applies to every return.
