Ms. Mistretta is originally from just west of the Philadelphia area in Pennsylvania and has spent the last 6 years in the DC area teaching. She has been teaching since 2005. She has had the opportunity to teach a variety of grade levels and support teachers and students. Ms. Mistretta holds a bachelor’s degree in Elementary Education and a Master’s degree in Mathematics Leadership. When Ms. Mistretta isn't at Rose Hill, you can find her on the softball field coaching and watching her daughter's play.  

This is Miss Osborn’s 8^th year teaching at Rose Hill Elementary and her first year in the Math Resource Position. In the fall, she cheers on the Penn State Nittany Lions and often attends home football games. She is very sad that won’t be happening this fall. Miss Osborn loves to go to Lake George in the summers, where she enjoys paddleboarding and swimming. She loves to read, especially historical fiction and realistic fiction. In May 2020, she graduated from Graduate School at George Mason studying Math Leadership and is so excited to share what she learned in her new math resource position.
