Licensed in 2 states
This provider holds licences in 2 states: Ohio and Texas. The practice address on file is in Willoughby, OH, 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 Nutrition covers
Chiropractic Nutrition is that specialty within the chiropractic profession that deals with the overall factors that affect the patient's ability to maintain the manipulative correction and thus sustain better neurological integrity. The Chiropractic Nutrition Specialist will perform extensive research on the patient's previous health history, ethnicity, and any family history related to what the patient is being treated for. Patients fill out questionnaires concerning dietary and sleep patterns and previous or present symptomology. A nutrition examination would be performed to assess areas such as absorption rates, adrenal function, kidney health, lung health etc. The patient is often instructed on how to check the pH of their saliva and urine, test for the presence of Candida Albicans, etc., at home. Outside laboratory testing includes blood, urine, hair analysis, food allergy testing etc. The patient's prescription and over the counter medications are recorded and analyzed.

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 | 0 | 0 | 3 | 0 | 0 | 2 | 0 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 0 | 0 | 4 | 0 | 9 |
Sum = 42 · next multiple of 10 = 50 · check digit = 8 · actual last digit = 8
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.
