Principal's Message

Dear Costello Parents,

I would like to welcome you to the 2019-2020 school year. My name is Mark Antkiewicz and I am the principal of Costello School. I am very excited to begin this new school year at Costello. We have launched a revived PBS program, which stands for Positive Behavior Supports. We will be teaching students desired behaviors and rewarding them through a ticket or cash system when they exhibit those behaviors. I look forward to an exciting new school year and endless learning opportunities for our students and their families.

On behalf of the entire Costello staff I would like to welcome you to Costello School. Our goal is to form a productive partnership to ensure our students can achieve their highest potential. At Costello, we know parents play a key role in their child's education and we ask for your support. In order for every child to achieve their best, we ask that students attend school on a daily basis, arrive on time and are prepared to participate everyday. If you have questions or input to help us achieve this goal, please do not hesitate to contact us with your suggestions.

Our continued goal is to keep parents informed of what is happening at Costello School and to involve our parents in their child's education. Continually check our school website for upcoming events.

We look forward to working with our students and their families to help guide them toward success by meeting the needs of each and every student.
