     Welcome to Freedom High School and the 2019-2020 school year!
    The 2019-2020 school year is the beginning of my 34th year in education. I have been a part of the Oakley/Brentwood community for over ten years. Each day I look forward to helping Freedom students as they move toward graduation and beyond.
    The best way to contact me is through Google Voice at (925) 384-0624. With Google Voice, you can reach me by calling or texting before and after school. You can also sent emails to treicheltd@luhsd.net. I will be happy to help you. If you wish to call me at school, please contact me at (925) 625-5900, extension 3810. Leave a voicemail message with the best phone number and time in which to call. 
    Thank you,
    Derek Treichelt
