Howdy! 

My name is Mary Freisner and I teach 8th grade Science at Murphy Middle School. This will be my third year teaching at Murphy- GO MAVERICKS! I am looking forward to also serving as the Science Department Head and Science Fair Coordinator this year. Any former students will know me as Ms. Casillas; I got married last fall and am excited about starting the school year with a new name!

I grew up in Plano, TX and graduated from PSHS in 2014. I then studied Biochemistry and Art at Texas A&M University and graduated in 2018.

Please feel free to contact me by email or phone if you have any questions or concerns.
