A former student of San Mateo High School filed a lawsuit today alleging claims for child sexual abuse by his former teacher and theater director, Roy L. Casstevens. Our client, Felix Montano, sued the San Mateo Union High School District, the City of San Mateo, and Broadway by the Bay, alleging Casstevens was a paid employee or volunteer of these three Defendants when he sexually abused him from 1976 to 1979, starting when he was 14 years old.

Montano is now a 58-year-old professional dancer, model, and actor living in Los Angeles. He alleges Casstevens sexually abused him when Casstevens was his drama teacher at San Mateo High School and his theater director for community theater programs run by the City of San Mateo and Broadway by the Bay.


Montano filed the civil lawsuit under California’s new statute of limitations for child sexual abuse. That new law opened a “window” for past claims of sexual abuse. The window opened on January 2, 2020 for three years, until December 31, 2022, and allows victims of child sexual abuse to file civil lawsuits even if their claims were barred by prior deadlines.

The lawsuit alleges that Montano met Casstevens the summer before Montano entered ninth grade in 1976. He had been a student at Burlingame Intermediate School, where he was bullied badly. That summer, he took a drama class Casstevens taught at San Mateo High School. Casstevens convinced Montano to attend San Mateo High School, partly due to its theater program.

During Montano’s years at San Mateo High School, the lawsuit alleges, Casstevens took him under his wing. Casstevens mentored Montano and got him involved in the high school and community theater programs. Casstevens used this grooming process to eventually seduce and sexually abuse Montano.

Because Montano was a minor when Casstevens had sex with him, Montano did not and could not legally consent to these acts under California law. Casstevens’ sexual attention to Montano was open and notorious and the Defendants should have protected Montano from this dangerous predator.

As we allege in the case, students and participants in the community theater productions frequently made jokes about and commented on the relationship between Montano and Casstevens. For example, a stage set of one of the plays had “Roy + Felix” painted as graffiti, clearly visible to the audience. Their sexual interactions were an open secret.

Casstevens’ sexual abuse of Montano ended in 1979, when Montano moved to Los Angeles during his senior year of high school when he was 17 years old.


In 1992, Casstevens was convicted of having sexually abusing a different male student at San Mateo High School in 1987. He was sentenced to one year in jail and five years’ probation. During the criminal investigation of that case, Casstevens admitted to admitted to sexually abusing multiple boys “during his teaching career” as far back as the 1970s, including Montano. Casstevens is currently a registered sex offender.


In a statement to the media, Montano says he filed his lawsuit now because the new statute of limitations allows him to seek accountability from the school and theater that failed to protect him and others from a predatory child molester. “I hope to right the wrong that was done to me as a child,” said Montano. “I met Casstevens when I was being bullied and felt like a social outcast. He took advantage of my trust and friendship to satisfy his sexual appetites, causing me years of guilt and shame.”

Although California courts allow victims of sex abuse to file lawsuits as John or Jane Doe, Montano filed the case using his real name to make a statement. “The abuse I suffered as a child was not my fault. I hope that by using my real name, other survivors will feel safe enough to come forward, whether they decide to use their names or not,” Montano said.


Roy Casstevens has been in the Bay Area his entire life and was very involved in theater.  He was born in 1946 and majored in drama at San Francisco State in the late 1960’s. He was the new drama teacher at Mills High School in Millbrea in the fall of 1970 and was there for two years. By 1975, he was teaching drama and directing the theater program at San Mateo High School, where he was still working at the time of his arrest in 1992.

Casstevens was also active in community theater. In 1972 he transformed an old theater into the Broadway Theater Workshop and offered courses to adults, high school students, and middle school students. In 1973, he became the theater director for the San Mateo Community Theater Company, a program of the San Mateo Parks and Recreation Department. The SMCT staged its performances at the auditorium at San Mateo High School, later known as the San Mateo Performing Arts Center. This remained the home of the company until 2011. Starting in 1999, SMCT began changing its name to Broadway by the Bay. Until his arrest in 1992, Casstevens worked both for the high school and the community theater company.

From what we know of Casstevens’ involvement with San Mateo youth through the high school and community theater, there are likely many more victims. Now that the California statute of limitations gives them a new opportunity to seek justice, we hope they come forward to tell their stories.
