Macey made her debut yesterday afternoon! We are so excited to welcome her to our family. Maybe she’ll be an @AustinElem Mustang in a few years!

My first day at @AustinElem and my last. This is a bittersweet moment as I say goodbye to the place I called home for 4 years. I am thankful for all of the wonderful people who have taught me and encouraged me along the way. Now it’s time to get ready for baby #2!

[Rachel Mastellar @mathstellar]

Well done ladies! Working along side you has been one of the biggest highlights of my career! @LAHarrisTX @angelamcadams_ @SchulzPaige #CISDCOVERSTORY #austinlearns

Thank you @MrsKemper for talking with me! I feel so blessed to work in a district that encourages teachers to do what’s best for kids. Thank you @Coppellisd for being a great place to work and learn! Now that is what I call a #CISDCOVERSTORY

My interview with @mathstellar. Her insight into bringing experts into the classroom is inspiring. Listen to hear how this educator builds authentic connections in math. #EveryoneCanCreate https://t.co/VUbo4tFufL
