Have a great school year!

Dear students,

As many of you already know, Sayre HS is not going to be a Promise Academy this year. Therefore, a big portion of the school's budget was cut. As a result, I was force transferred to Bartram High School where I will be for the remainder of the year.

I will miss all of you dearly. Seriously. I want you all to know that if I had a choice, I would have stayed at Sayre, to continue teaching you, to mentor you, to lend a listening ear, to watch you grow.

Please keep in touch! I'd like to know how you are all doing. My email address is: wchan@philasd.org. You can email me anytime-- I can still help you with homework assignments, offer advice, etc.

At the very least, write down my email address and let me know when you graduate high school. I want to watch you walk across that stage!

Take care,
Ms. Chan

(:
