Romero contacted both Ken Browning, his primary recruiter, and Art Kaufman, UNC's linebackers coach, and told them the news.
"They were proud, they were happy," Romero said. "They said this is a beginning of something big."
Romero selected UNC over fellow finalists Virginia and West Virginia. Those three aforementioned schools plus Maryland offered him a scholarship.
A March visit to UNC played a major role in Romero's decision to ultimately commit to the Tar Heels.
"It gave me a chance to see how they were [and] how life was [at UNC]," Romero said.
Although he says his commitment is firm, Romero hasn't ruled out the possibility of visiting other schools.
"I'm going to still take a few visits, but most likely [UNC] is where I'll be attending," Romero said. "I've really visited all the schools that have offered me, except for Maryland."
There are a handful recruits in the Tidewater Area of Virginia, where Romero resides, who are also major UNC targets.
"I'm going to try to get a few [Tidewater recruits] to come with me – Demetrius Nicholson and Travis Hughes," Romero said. "Those are two big ones that I'm really going to try to get that I know have interest in North Carolina."
Romero has started the past two seasons at outside linebacker for Phoebus. As a junior, he totaled 88 tackles, including 20 for a loss and 30 sacks.
