The Firm
Independence is not a marketing claim. It is the entire product.
For nearly five decades, Truehn & Co has refused referral fees, restricted advisory revenue from audit clients, and rotated lead partners every five years — well ahead of regulatory minimums.
We answer to a single partnership, not a holding company. That means our auditors can sign — or refuse to sign — without a conversation about the next quarter's pipeline.
