Principal's Message

 Vicki Pucket

February is well underway and springtime is just around the corner! In addition to the regular activities taking place at the high school, this month we have been celebrating Black History Month. Spring sports will be starting soon; we are looking forward to a new season of sporting activities. To celebrate Valentine’s Day, the choir students surprised many students and staff with special songs. We are also very proud that 57 students qualified to complete in the State DECA competition in March. Thank you for all that you do to make our school such a vibrant personal and academic environment for our students. Read More
