This school is an absolute mess, as a past student who has dealt with the staff and peers alike this school is not worth sending your child to. The staff does not care about your children and their safety. I am friends with a few students who are bullied on a daily basis, they have received physical threats from the student and the staff does absolutely nothing about it. If i was a parent that has thoughts of sending their children to this school, i would highly rethink it. home school your children parents.

I am a current student at this school and I wouldn't want to go anywhere else. The staff is absolutely amazing and care about you, especially the principal. He has turned this school around and made it absolutely amazing. I love the teachers and the rest of the staff. Our school is our little community and we all come together when it's needed. Our school environment is both fun and friendly, and I would definitely recommend this school.

As a student of this school, I believe that the quality of education is amazing. There are so many amazing teachers who put effort into their lessons. The school also offers numerous extracurriculars including DECA, student council, and SADD. The thing I like most about HDHS is the personal connections you are able to establish with the teachers and staff. You will always be able to find a trustworthy adult to talk to. I truly am so happy I was able to attend HDHS and hope to come back and visit soon. Reading reviews of angry parents and kids will never be able to truly tell all that this school has to offer.
