Mrs. Sheila Holsinger

Hello! This is my 26th year of teaching in Plano ISD. I taught at Hendrick Middle School for four years, and I am in my 22nd year here at Plano Senior. I love teaching and hope that my students know that I am here to help them be successful. I hope students will feel comfortable in my classroom and will ask and answer questions to further learning for everyone in the room. 

I am currently teaching English 3E, English 3, English 4, and AP English 4 (Literature and Composition). In my spare time, I love to read, cheer on all of my teams (Wildcats, Texas Aggies, USC Trojans, & Dallas Cowboys), go to concerts, spend time with my family and friends, watch excellent tv shows and movies, and travel. 


I look forward to a great year!
