Reading this record
The practice bills under the legal name Kathryn Najafi Tagol MD A Professional Corporation and registered Eye Institute of Marin as its trading name, so an insurance statement may show a name that does not match the sign on the door. The entry was refreshed in April 2025, putting it among the 92 of 543 San Francisco-Oakland-Fremont records updated in 2024 or later, so the contact details are more likely to be current than most of this metro.
For local context: San Rafael holds 15 registered eye care practices in this snapshot, 7 of them optometry and 8 ophthalmology, in ZIP codes including 94903. 12 of them took an NPI before this practice did. The closest is Bonnie Nickel, M.d, in San Rafael, 0.7 miles away.
None of this is a licensing check. CMS issues an NPI so a provider can be identified in billing transactions, and states plainly that issuance does not ensure or validate that the holder is licensed or credentialed. The California boards hold the licensing record, and the practice itself is the only source for what it charges today.

What to expect to pay at an ophthalmology practice like this
The NPI registry holds no prices, so nothing here is a quote from Eye Institute of Marin. Based on this site's own price research, an ophthalmology practice typically charges $150 to $300 or more for an exam without insurance, against a national average of about $136 and roughly $25 once a vision plan pays its share.
Ophthalmology visits are usually medical rather than routine, which changes who pays: medical insurance and Medicare Part B cover a medically necessary exam, while a routine refraction for glasses is normally not covered. Ask whether the visit will be billed as medical or routine before you book, and compare with the 386 optometry practices on the San Francisco-Oakland-Fremont page if you only need a prescription.
