On Nov. 25, the Locust Valley High School 2020 Girls Basketball team was honored by the Town of Oyster Bay for clinching the Nassau County Class A Championship this past spring.

Locust Valley High School Embraces Season of Giving

Locust Valley High School students and staff joined forces to collect Thanksgiving meals for those in need this holiday season. A total of 18 baskets and 8 tote bags full of food were collected, ensuring that 26 families will have traditional Thanksgiving meals and some extra goodies on their tables to enjoy with their families. The generous Locust Valley High School community also collected $200 which was used to purchase gift cards and additional food items to add to the donations. Organized by high school social worker Bidania Criscuolo, the food drive supported the Grenville Baker Boys and Girls Club as well as families in need who aren't associated with the club. Special thanks to high school juniors Marilu Famiglietti and Janelly Vasquez for assisting Ms. Criscuolo with assembling the baskets.

“It fills me with pride to be part of a school community that puts others first,” said Superintendent of Schools Kenneth E. Graham, Ed.D. “On behalf of the entire district, I thank our selfless, caring students and staff members for going out of their way to help others.”
