Detectives with the Broward Sheriff's Office have arrested a 24-year-old man on multiple sex crime charges involving students at a Deerfield Beach private school, according to investigators.

Authorities are urging any additional victims or witnesses to come forward. 

According to BSO, Ronison Exavier, an assistant athletic coach at Highlands Christian Academy, was arrested Monday, following reports of lewd and lascivious molestation.

Detectives said the family of one victim contacted the agency after learning Exavier summoned the victim to his office on Wednesday, Oct. 15, and inappropriately touched her. 

Additional victim identified during BSO investigation

During the investigation, detectives discovered a second victim who told investigators Exavier had committed similar acts against her. The first incident occurred in the fall of 2024 and the second in July 2025, according to the sheriff's office. 

Detectives said they made contact with Exavier at his Coral Springs home, where he was taken into custody. 

Exavier faces three counts of soliciting and/or engaging in sexual conduct with a student, two counts of lewd and lascivious molestation or conduct and two counts of touch or strike battery. 

Because Exavier worked closely with students at the school, detectives said they are concerned there may be additional victims.

Anyone with information is asked to contact BSO Special Victims Unit Detective Eric Wilson at 954-321-4460 or Broward Crime Stoppers at 954-493-TIPS (8477).

Experts advise parents to watch for behavioral changes

As a former assistant athletic director at Highlands Christian Academy faces serious charges of molesting two students on campus, child safety experts urge parents to be vigilant for changes in their children's behavior that could signal abuse. 

Amanda Altman, CEO of Kristi House, a child advocacy organization, emphasized that abuse most often comes from a trusted person close to the family. "In about 90 percent of the cases, the abuse is at the hands of a family member or a close, trusted person to the families," she said. 

Altman warned parents to notice shifts in personality. "For example, if you have a child that's really outgoing, and then all of the sudden, you notice that they're starting to be more withdrawn, that could definitely be a sign that there is some abuse happening," she explained. "Children often regress in their behaviors." 

Concern and action from parents 

Parents in the school community expressed concerns and prayers for the victims, acknowledging how any child could be affected by such abuse. One parent remarked, "We're praying for the victims, obviously. We have children, so it could be anyone's child." 

Others are considering removing their children from the school. "I don't think we'll be keeping her here any longer. We're considering to get her out," said one worried parent. 

School response on student safety 

Highlands Christian Academy has terminated the accused staff member and stated that "the safety and well-being of our students remains a top priority."
