List of specialists in Dr. Mario World

In version 1.4.0 of Dr. Mario World, versus mode introduced the specialists feature. This feature's debut is also during the start of season 3 in versus mode. For a duration of time, usually a week, four or five selected doctors are assigned as specialists, in which they will receive certain boosts that gives them added advantages during a match. As of now, the only doctors that haven't been selected as specialists are Dr. Fire Mario and Dr. Koopa Troopa.

Typically, the specialist period will last until it is one hour before the next one starts, which is the only period of time when no doctors have any added advantages. Unless otherwise stated, all start times are 06:00 UTC and all end times are 05:00 UTC.
