Founded in 1904 in northern Colorado, Professional Finance Company is one of the longest-operating collection agencies in the country. Most of its work is contingency collection for healthcare providers — the provider still owns the account — though its own materials also describe debt purchasing among its services, so the validation response identifying the current creditor tells you which arrangement covers your account. Its own consumer disclosures direct written requests to the Greeley address above.

Professional Finance Company wears two hats depending on the account: sometimes it contacts you on behalf of the original creditor (which still owns the debt), and sometimes it is collecting an account that has been placed or transferred. You usually can’t tell which from the letter alone — and the difference matters for who you ultimately negotiate with. A written validation demand settles it: federal law requires the response to identify the current creditor.

Your rights in the first 30 days

Federal law front-loads your leverage. Under 15 U.S.C. § 1692g, if you dispute the debt in writing within 30 days of receiving the validation notice, Professional Finance Company must cease collection until verification is mailed to you. Under 12 C.F.R. § 1006.26 (Regulation F), no collector may sue or even threaten to sue on a time-barred debt — a strict-liability rule. And under 15 U.S.C. § 1692e, misrepresenting the legal status or amount of a debt is itself a federal violation. None of these rights depends on whether you owe the money.

How to respond — the right first move

One certified letter does all the work: it disputes the debt in writing (preserving the § 1692g pause), demands the itemized history, the signed agreement, and proof of authority to collect — including the chain of assignment showing Professional Finance Company owns your specific account, and states plainly that nothing in it acknowledges the debt or waives any defense. Send it certified mail, return receipt requested, keep the green card, and say nothing of substance on the phone until the response arrives. The preview below shows how it opens.

Check the dates before anything else

A century-old medical collector means the practical question is account-level accuracy, not legitimacy: insurance adjudication errors, financial-assistance adjustments that never posted, and balances already settled with the hospital are the recurring patterns. Demand the itemization, match it against your insurer's final EOB and any financial-assistance award letter, and see our medical bill dispute guide for the parallel letter to the provider.

Every state caps how long a collector has to sue — and in most states a payment or signed acknowledgment can restart that clock. Before any payment on an older account, run the dates against your state’s rules: see our debt statute of limitations by state guide and the medical bill dispute letter guide.

If they sue

Respond — always. Most collection suits end in default judgments because the consumer never answers, and a default converts a contestable claim into a garnishable one. Answering puts ownership documentation, itemization, and any limitations defense squarely in play, and your dated validation letter becomes Exhibit A: proof you demanded the paperwork before they filed.
