Headmaster Crumbs is the age of 800 and was asked to be at the Russo family competition as the Wizard Council.

Professor Justin Russo
Professor Justin Russo was competing in the Russo Family Competition and after Alex won the Family Competition and was gained full wizardship, Professor Crumbs was proud of Justin's decision and declared that he was going retire as Headmaster of WizTech and gained Justin full wizardship who was appointed to Headmaster of WizTech. In the show's finale, Justin keeps his full wizarding abilities by replacing Professor Crumbs as the new Headmaster of Wiz Tech.
In the new series, Justin later married Giada Russo, a mortal after getting fired from WizTech due to an unicorn incident, which caused him to leave the wizarding world and magic behind for good and begin another journey in life outside of wizardry until the arrival of young wizard Billie.
Professor Alistair Goodspeed
Professor Alistair Goodspeed became of WizTech after Justin Russo got fired. He was driven by jealousy of Justin's success as headmaster, that he orchestrated eents that led to a disastrous graduation day incident involving unicorns. Under the guise of being a hero, he casted a spell to incapacitate Justin, which allowed him to take credit for averting disaster. After Justin's Removal, Goodspeed got the Headmaster position but later resigned to join the Wizard Tribunal. However, his dark past was exposed when Alex Russo uncovered a magical mental projection of him that Goodspead had previously implanted, leading to the likely rescindment of his Tribunal offer. Goodspeed's tenure at WizTech serves as a reminder of the dangers of ambition and deceit within the wizarding world.
