Who checks our work
The Medical Review Board reviews MediSkill's health content for accuracy. When an article lists a board member as its medical reviewer, that person checked it, and their name is shown on the page.
MediSkill picks speakers for its trainings event by event, and there is no fixed schedule. We choose the best fit for the subject. A speaker may be a review board member, but often it is someone outside the board. Sometimes a speaker later joins the board.
Our articles are written by named authors or the MediSkill Editorial Team. Articles that list a medical reviewer were reviewed by that clinician. You can read how review works in our editorial process. If you think we got something wrong, email contact@mediskill.com.
