YOU + DLS = GREATNESS!

Every student can be successful with the right support group. Our Department strives to meet the needs of the class as a whole and each student individually. This means meeting our struggling students at their current level of understanding and challenging all of our students to succeed beyond their expectations. We encourage critical thinking and incorporate problem-solving opportunities in all of our classrooms. We offer a variety of levels of classes that not only challenge the students but prepare their skill sets for college and the rest of their lives.
