Call the office to confirm.
Licensed in 2 states
This provider holds licences in 2 states: Iowa and Illinois. The practice address on file is in Davenport, IA, but a licence in another state usually means they see patients there too — either at a second location or by telehealth. If the address above is far from you, it is worth calling to ask whether they practise closer to where you live.
Licence numbers are self-reported to NPPES at registration. They do not confirm a licence is currently active, in good standing, or valid for the specialty shown — only the state board can tell you that, which is why we link to each one.
What Audiologist covers
(1) A specialist in evaluation, habilitation and rehabilitation of those whose communication disorders center in whole or in part in hearing function. Audiologists are autonomous professionals who identify, assess, and manage disorders of the auditory, balance and other neural systems. Audiologists provide audiological (aural) rehabilitation to children and adults across the entire age span. Audiologists select, fit and dispense amplification systems such as hearing aids and related devices. (2) An audiologist is a person qualified by a master's degree in audiology, licensed by the state, where applicable, and practicing within the scope of that license. Audiologists evaluate and treat patients with impaired hearing. They plan, direct and conduct rehabilitative programs with audiotry substitutional devises (hearing aids) and other therapy.

Full NPPES record
An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check
How the check works, step by step
Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.
| Digit | 8 | 0 | 8 | 4 | 0 | 1 | 6 | 6 | 9 | 4 | 9 | 5 | 5 | 0 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 6 | 3 | 9 | 8 | 9 | 1 | 5 | 0 |
Sum = 67 · next multiple of 10 = 70 · check digit = 3 · actual last digit = 3
A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
