Principal's Message

Christina Martinez, Principal
Tigers,
 
Welcome back! I hope you had a safe and restful Winter Break and that you’re excited about second semester. 2020 was a difficult year. Perhaps even a year that many of us would like to forget. Despite the changes and challenges, there are blessings to be found. Whether it was more time spent with family, or renewed hope for racial justice in our community and in our world, 2020 has shown us that we have the power to change for the better--body, mind, and spirit. As we head into 2021, let’s prepare ourselves to make the most of the new possibilities and opportunities that lie ahead.
 
If you haven’t already given some thought to your New Year’s resolutions, I encourage you to reflect and set some academic and personal goals. Remember: you are starting fresh. You have resources available to you and people at school who love and care for you. Together, we can take it to a whole new level! Keep in mind all the support that is within your reach:
 
●       Office Hours from 8:00- 8:30am and 2:00-3:00pm, Tuesday through Friday
●       Support time built into 90 minute block
●       2nd  period check-in EVERY Monday
●       Your counselor
●       Your principal!
 
Stay strong, focused, and continue to strive for excellence in all areas of your life.
 
As a reminder, we are starting 2nd semester in a distance learning format. There are some changes to the bell schedule based on input from staff and students. Please review the revised bell schedule so that you know what to expect. I will continue to keep families informed of any updates to the school program through Canvas e-mail and the Sunday call.
 
Lastly, please be aware that school is not in session on the following dates:
January 18th  – MLK JR. Day
February 8th – Lincoln’s Day
February 15th – Presidents Day
 
Tigers, I can’t wait to see the amazing things you will accomplish in 2021!
