What we looked for

We weren't able to independently verify OCD-specific expertise signals for this provider based on publicly available information. This is why their score is lower — not because they're necessarily a poor clinician, but because the evidence we look for isn't publicly visible.

Signals we couldn't confirm:

  • No IOCDF directory listing found
  • No publicly documented ERP methodology
  • No OCD-specific training credentials found
  • No OCD-related research publications found
  • No affiliation with a recognized OCD specialty clinic

This doesn't mean this provider can't help with OCD — it means patients should ask directly about their ERP experience and OCD-specific training before booking.
