Shaun Weiss is celebrating one other milestone in his wonderful turnaround … and the ‘Mighty Geese’ star is marking the event with another child actors from again within the day.

Shaun reached 4 years sober Thursday, and he was surrounded by a whos who of ’90s stars on the Corbin Bowl in Tarzana, CA … the place he thanked everybody who helped him keep on the straight and slender and carried out a few of his stand-up comedy routines.

Thomas Ian Nicholas from the ‘American Pie’ franchise and “Rookie of The Yr” supplied a few of the evening’s leisure … singing and enjoying guitar.

Different ’90s celebs supporting Shaun included … Nate Richert from “Sabrina The Teenage Witch,” Natanya Ross from “The Secret World of Amex Mack,” Marty York from “The Sandlot,” plus John Diresta from “Mickey Blue Eyes” and “Miss Congeniality.”

The milestone is large for Shaun … he appeared to hit all-time low again in 2020 when he was arrested for housebreaking and meth, posing for an notorious mug shot. Again then, he used to reside on the streets.

Within the years since, Shaun’s cleaned up his act, his look and gotten again into Hollywood … touchdown a film gig and doing stand-up comedy.

Seems like Shaun’s obtained a fairly good help system too.

Stick with it!!!
