Current Principal Communiqué

  • January 2020

    Dear Clemens Family,

    As we head into the winter break, I would like to thank students, staff, and parents for contributing to the Clemens community that we are all so proud to be part of. We have had an outstanding first semester with many opportunities for our students to demonstrate their amazing talents and passions. Thank-you to all of the staff who have made these opportunities possible.

    You can expect first semester grades to be posted in TxConnect on January 7th. Please review grades and do not hesitate to contact your child’s teacher should you have any questions. I encourage all parents to continue to stay connected with the school as we know that your involvement has a positive impact on student learning and social well-being.

    I want to remind you that our campus will be closed for the holidays on Friday, December 20th at 1:30 PM and will re-open on Tuesday, January 7th at 7:45 AM.

    Lastly is the parent bulletin and January calendar. We hope you enjoy reading about the amazing things our Buffs are doing!

    We look forward to welcoming students back for a terrific second semester on January 7th.

    Thanks again for your continuous support.


    Missy Sosa
