The Florida Department of Health's MQA License Verification portal is free and needs no account. Search by name or by the CH- license number from the listing.
The licensee page shows status (Clear/Active, Delinquent, Suspended, Revoked), the practitioner profile, and a Discipline/Admin Actions tab with public complaints, emergency orders and final orders.
Also check the practice's malpractice history in the practitioner profile and confirm the clinic address matches the one you are booking. A clinic that will not give you a license number is a red flag.
