Our provider data is gathered directly from physicians and publicly available databases. Providers who verify their profiles gain the ability to update information, offering additional details about their specialties,education, treated conditions, performed procedures, and accepted insurances.
Reviews on Vitals are submitted by users only. Recognizing the valuable insights these reviews offer into a doctor's reputation, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Importantly, providers cannot delete or alter reviews independently. Reviews can only be deleted or changed following an internal assessment by our customer service team.
Your feedback is highly valued and we encourage you to contact our support team should you encounter any issues.
