After winning the family wizard competition, due to Alex helping him get his foot unstuck, he gives the title of Family Wizard to Alex. Professor Crumbs then makes Justin the Head of WizTech.
His girlfriend is Juliet Van Heusen, who is a vampire.
Justin is kind, generous, smart, and hardworking. His relationship with Alex is complicated, and he is often annoyed by her; he sometimes gets back at her in revenge for whatever she does that causes problems for him.
Justin was born to Jerry and Theresa Russo in New York City, in the United States. Justin became the head in magical teaching, though he was teased by his younger brother. In the first two seasons, Justin spent time getting girlfriends and solving his siblings' magical troubles.
In the third season, Justin tried to find his vampire girlfriend Juliet after she was kidnapped by a mummy. Justin also tried to abort a Wizard Revolt, begun by a wizard named Stevie who lost the Wizard Contest. In the end of the season he exposed the Wizard World to American agents after being trick about an allien invasion. However this was revealed to be test to see if the Russos could keep the magical existence secret. Because they failed, Justin and Alex (who made a press conference to expose magic) were lowered to level 1 of magic (Justin was in level 6, the maximum).

Above average intelligence:In many stories it's shown that Justin knows many things, his knowledge includes but isn't limited to, history, science, mathematics and general knowledge. In "Alex's Brother, Maximan" he builds a working robot out of house hold items, in "Franken Girl " he combines magic and science to build a frankenstein like robot.
Hand to hand combat: as shown in "Wizards vs. Werewolves" he is quite skilled in hand to hand combat, being able to hold on his own aganist a werewolf for a little while, and seeing as werewolf's are stronger, faster and more agile than humans by quite a bit, that is something to be inpressed by.
