Letter to the Class of 2020

Graduates and Families of the Class of 2020,

As we approach the awaited countdown to the 95th Commencement in Islip High School’s history, there is no better time than now, to thank all of you for your patience, unwavering support and confidence in our faculty and staff during our distance learning experience. Islip High School faculty and staff worked so hard to create and modify events to ensure that our amazing graduates knew how much they were loved, missed and appreciated for all they accomplished during their time at Islip, culminating this week with what is shaping up to be a wonderful family-oriented series of commencement ceremonies.

At this time, I would like to formally invite you all to join me and the rest of the Islip High School Administration, Faculty, Staff and the Islip School Community in recognizing the members of the class of 2020 who were nominated and selected as award winners. Our first presentation linked below is our Virtual Senior Awards Ceremony which will present a variety of academic, service and achievement awards and scholarships from 65 families, community members and organizational donors to graduating seniors totaling more than $90,000. Our second presentation is our Virtual Athletic Awards Program honoring the senior varsity athletes of the graduating class of 2020.

I would like to publicly thank the many administrators, faculty, and staff members whose creativity and hard work made these presentations a reality. On behalf of the Islip High School Family, congratulations and enjoy the presentations.

A Message from the Principal:

Dear Islip High School Families,

It is my sincere hope that you receive this letter in the midst of an enjoyable and relaxing summer vacation. For me, this letter is both exciting and yet very humbling, as it is my first opportunity as the new Principal of Islip High School to officially "Welcome You Back" for the start of the 2019-2020 school year.

Since I was hired, my time in Islip has been nothing short of remarkable. Every student, parent, teacher and staff member that I have encountered has been kind and helpful. Learning about the wonderful programs and the opportunities that have been created for our students has not only inspired me, but also confirmed all of the fantastic things I have heard about Islip High School, its outstanding students and staff and the "Pride" that the community has for the total school program.

I have learned that Islip is built upon rich traditions of excellence, the truest form of community pride. At its core is a school system whose commitment to the growth, enrichment, and success of all of its students is second to none. I am truly honored to have been selected by Central Administration and the Board of Education to join the Islip School District, with its exceptional students, faculty, staff and administrative team.

For more than twenty years, I have been fortunate to have had many valuable and unique opportunities within both the educational and professional arenas. These experiences have paved the way for me to become the administrator and educational leader that I am today. I began my career in the Bethpage School District where I was a secondary social studies teacher for fourteen years. For the past six years, I was an assistant principal at Kennedy High School in the Bellmore-Merrick School District. This time has provided me with a deep insight as to the true value and significance that a tradition of excellence, whole life learning and a "student first" focus has upon a district and its community as a whole. It allowed me to play an active role in the creation of instructional, curricular, technological and athletic programs, as well as operational ventures aimed at student growth, achievement, and real-world experiences. I look forward to bringing a commitment to excellence, a creative and innovative vision, and a positive attitude to the current and future students of Islip High School.

Once again, I am so thankful for the opportunity to become a part of the Islip High School community! I look forward to getting to know and work with each one of your children as we continue to strive to move Islip High School amongst the educational leaders in New York State.

Best regards,
Jon LaRochester

HS Student PSA Chosen for National Contest

Anti-vaping public service announcement “It Won’t Happen to Me,” created by Islip High School video production students Chaiti Paul and Stephania Teran, was selected as a National Finalist in The Greatest Save Teen PSA Contest, sponsored by KinderVision/The Greatest Save and Major League Baseball. Paul and Teran’s video won the Long Island Region during the last school year.

“Their PSA is being used in schools around the country to help teens learn about issues such as vaping,” said their teacher, Mike Reilly.  “We take great pride in our fully produced, filmed, scripted, and edited projects in our video production class and it is obviously noticeable to many around the country as we have won or placed in several national competitions. With New York being the media capital of the world, and with continuous growth in the media field, our students are certainly having an opportunity to explore these avenues.”

Four exemplary and patriotic Islip High School students – Lauren Calloway, Elizabeth DeSimone, Emmie Jensen and Sally Voska – chosen for last summer’s Empire Girls State leadership program were honored on Nov. 16 in a ceremony at the Islip American Legion Auxiliary Rusy-Bohm Post 411 in Islip. It was the first time in more than 30 years that four female juniors were chosen for Girls State from Islip in one year.

Due to COVID-19 restrictions, the weeklong 2020 program was held virtually online instead of at SUNY Brockport. This permitted alternates Jensen and Voska to attend along with Callaway, who was selected to attend as a citizen. Post 94 in Babylon accepted additional Islip alternate DeSimone to fill their citizen’s spot.

Special guests at the ceremony included Islip Town Supervisor Angie Carpenter and Dennis Bennet, representing State Sen. Phil Boyle, as well as Suffolk County American Legion Commander James Beecher, Suffolk County Empire Girls State Chairwoman Patricia Bergin, Rusy-Bohm Post 411 Auxiliary President Paulette DeCrescenzo and Rusy-Bohm Post 411 Commander Dominick DeCrescenzo.
