A Lakota East High School teacher pleaded not guilty Tuesday in Area II Court to having a sexual relationship with a former student, allegedly starting when she was 17.

Justin Daniel Dennis, 42, of West Chester Twp., was arrested Monday and charged with a count of sexual battery, a third-degree felony. The complaint filed with the court claims Dennis, a Lakota East teacher, had a sexual relationship with the student that began in the 2021-2022 school year. It started in December 2021 during her senior year, and ended in September 2022, according to court records.

Dennis, also listed as a Lakota West teacher on the district’s website, was an advisor to a student assistance group in which the victim participated. The teacher was taken into custody without incident, according to the Butler County Sheriff’s Office.

Encounters during the relationship allegedly occurred in Dennis’ classroom, in the victim’s workplace parking lot, at his home in West Chester Twp., and at his former home in Liberty Twp., according to court records. The victim shared with the sheriff’s office investigator a text thread between her and the teacher where they were messaging about their past relationship.

Justin Daniel Dennis, 42, was arrested on Monday, Aug. 4, 2025, on one count of sexual battery. The charge stems from an alleged incident involving a female student during the 2021-2022 school year. PROVIDED

Dennis was arraigned by video in Area II court in Hamilton on Tuesday morning. A cash or surety bond was set at $100,000, and he pleaded not guilty.

“This case is deeply disturbing,” said Butler County Sheriff Richard Jones. “Teachers are placed in positions of trust and authority, especially when working closely with students. Just like law enforcement officers, they are expected to uphold the highest standards of conduct.”

The sheriff said Dennis’ alleged actions and “betrayal of trust will not be tolerated.” The sheriff’s deputies and investigators “will continue to aggressively pursue justice for victims and ensure the safety of our children,” Jones said.

Lakota Local Schools spokesperson Betsy Fuller said student safety is “always our first priority.”

School administrators were notified late Monday afternoon of Dennis’ arrest, who was immediately placed on paid administrative leave after district leaders learned that a complaint had been made.

“As this is a personnel matter and the complaints have been under investigation by both law enforcement and now the district, we are not able to provide further information at this time,” said Fuller, adding the district is “cooperating fully” with the Butler County Sheriff’s Office.

“This individual and their alleged actions do not align in any way with the values or character of Lakota Local Schools. Again, the safety of our students is always our first priority, and we will investigate any accusation or threat.”
