Current Principal Communiqué

  • November 13, 2019

    Dear Clemens Family,

    This letter is to inform our Clemens community that we will be initiating the Not On Our Campus (NOOC) campaign starting the week of December 2, 2019. In addition to the social and emotional learning opportunities offered through our campus counselors, the Not On Our Campus campaign includes lessons and activities about respectful and inclusive behavior. This campaign champions “an ongoing commitment to empower students to create safe and inclusive environments...”

    Recently, campus administrators were made aware of incidents of disrespectful and derogatory behavior by some of our students towards each other. One incident of disrespect is too many and such behavior does not exemplify the expectation we hold for all students, faculty, and staff as members of the Clemens Buffalo family.

    The Not On Our Campus campaign will provide student activities that identify problems such as harassment, intimidation, exclusionary, and discriminatory behaviors with peer to peer responsive actions that can help eliminate an unwelcoming and unsafe environment. It was after extensive research and investigation that we feel this program can best serve our students and Buff community.

    During the first few weeks of the NOOC campaign, Clemens student groups will implement activities that teach students how to more effectively communicate and interact. As a part of the campaign, students will be asked to take a pledge to stop hate and intolerance.

    This campaign is on-going and will continue throughout the school year to ensure that our students maintain a commitment to eliminating hate and intolerance as part of their daily interactions.

    We appreciate your support in this endeavor and hope that you can continue the conversation with your children at home about safety, respect, and inclusion. Together, we can strengthen our community.


    Missy Sosa
    Clemens High School Principal
