My name is Mr. Siedlecki and I will be your Principal. Most students call me Mr. S. I would like to welcome you to NDA. We are looking so forward to having you at our school. I know that coming to a new school can be stressful and exciting at the same time. We want to try to help you transition to our school in the best way we can. I have included some video links below to share with you some of the great things that happen at NDA. Please click on the links below.
