Getting there

The practice address on file is 3600 W FULLERTON AVE, Chicago, IL 60647. We have not yet mapped what surrounds this office — parking, transit, and nearby pharmacies are added as our data collection reaches each location.

Credentials and Medicare

Licensed in 10 states

This provider holds licences in 10 states: Connecticut, Florida, Georgia, Illinois, Massachusetts, New Jersey, New Mexico, New York, Utah and Virginia. The practice address on file is in Chicago, IL, 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 Psychiatric/Mental Health covers

Definition to come... NUCC Health Care Provider Taxonomy, code 363LP0808X

All registered taxonomy codes

This provider registers 13 taxonomy codes. The primary code is what appears on most claims; the others record additional recognised specialties.

The taxonomy records how the provider classifies their own practice. It does not confirm which conditions they currently treat, whether they are accepting new patients, or which insurance they take — call the office for that.

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.
