He attended Sharon High School through his junior year before making a significant decision to transfer to Wellington High School in Wellington, Florida, for his senior year.

As a senior at Wellington, Brebbia had a 10–1 win–loss record with a 0.83 earned run average (ERA) and recorded an 18-strikeout game. His performance drew attention from college scouts, and he ultimately committed to Elon University, where he continued to develop as a pitcher for the Elon Phoenix.

He also played summer league baseball for the Mankato MoonDogs of the Northwoods League in 2009, gaining valuable experience against higher-level competition.
In 2010 and 2011, Brebbia played collegiate summer baseball for the Orleans Firebirds of the Cape Cod Baseball League, one of the most respected amateur leagues in the country. During his junior year at Elon in 2011, he went 7–1 with a 1.76 ERA in 27 relief appearances and was named First Team All-Southern Conference. The New York Yankees selected him in the 30th round of the 2011 MLB draft, launching his professional career.
