I loved my experience at Saint Mark’s High School. The academic curriculum was very challenging and did an excellent job at preparing me for further education. I have made many lifelong friends at Saint Mark’s. With any school, there will be teachers that you absolutely love, and teachers that aren’t your favorite. I have grown in my athletic, academic, and social skill level at Saint Mark’s. I would change the lunch options - although there are tasty dishes, I wish there was more healthy food options other than the one salad bar. I would also update the bathroom facilities. Overall, I would recommend Saint Mark’s to anyone looking to attend.

Best kept secret in Delaware! Great environment for high school students. Teachers are great Christian role models and challenge kids to be responsible and work to the best of their abilities. My other two sons attended St. Marks and were well prepared for college and beyond. There are plenty of ways to get involved from sports, the arts and clubs. Students are very inclusive. Never heard of any bullying. Great school!
I graduated many years ago so I'm not sure what has changed, but I was heavily involved in theatre band and chorus. The school made me choose to go into theater for a living. When in college, there was no other high school that could compare with the curriculum when I talked to other students. I've been working in Atlantic City for 32 years now.
