What Partly Checked Means for Baseline Tox Medspa

1 of 1 named clinician matched to current Arizona professional license records.

Last checked: September 27, 2026

1 further name on the clinic's website is not listed: we could not read it with enough confidence, and no current license record matched it. This clinic does not name a physician on its website, or the physician it names has not been matched to a license record yet.

Verified Injector could not establish every condition of its verification rule for Baseline Tox Medspa.

This status is not a finding that any clinician is unlicensed.

What We Checked

  • We read the clinic's own website.
  • We identify the clinicians it publicly names.
  • We check each one who holds a medical or nursing credential, or whom the clinic calls Dr., against the state licensing board's records.

Staff without a medical or nursing credential, such as aestheticians, are not checked, and we do not verify anyone the clinic does not name.

What Verification Does Not Mean

  • It does not evaluate clinical skill, judgement or technique.
  • It does not evaluate treatment outcomes or patient experience.
  • It does not guarantee the safety or quality of any treatment.
  • It does not cover anyone the clinic does not name on its website.
  • It does not report disciplinary history beyond what the licensing board's own record shows.
