Credentials and Medicare

Licensed in 15 states

This provider holds licences in 15 states: California, Colorado, Connecticut, Florida, Idaho, Illinois, Kansas, Kentucky, Louisiana, Missouri, North Carolina, New Mexico, Ohio, Texas and Virginia. Multi-state licensure often means the provider works near a state border, covers more than one office, or delivers care 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 Family covers

Definition to come... NUCC Health Care Provider Taxonomy, code 363LF0000X

All registered taxonomy codes

This provider registers 15 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.
