Michelle V. Costilla

My name is Michelle V. Costilla and I am GP High School's Library Media Specialist.   I am a former WILDCAT, so that makes working for GP an extra honor! This is my 18th year with this outstanding district. I started out my career as a second grade teacher at T.M. Clark Elementary, which is where I went to elementary. I spent ten AWESOME years there and enjoyed it very much. While I was teaching I started working on my Masters degree in Library and Information Science. Upon completion I came to work here at the high school as a library assistant, my goal was to get library experience. When a librarian position became available at GP Middle School, I applied for the job and got it! I spent three amazing years at the middle school gaining a lot of experience. Now I am back here at the high school and I am super excited!

The G-P High School Library mission is to support the curriculum for both our students and staff, to provide a welcoming environment, and to promote learning and the love of reading. We offer a variety of resources including books, magazines, databases, and computer access to help provide the information our students need. My goal for our school library is to be the welcoming heart of our school where all come to learn, discover, create, and connect.

I know these few past few school years have been different, however we are and have always been committed to providing our students with quality literature. While many of us prefer reading paper books, during the age of Covid-19 we added more to our digital resources. eBooks and audio books are becoming omnipresent.  During the 2020-2021 school year our district joined Overdrive's Region 2 Consortium.  This gives ALL currently enrolled GP students access to 1000's of digital library books!  Please visit our "Sora" library page for instructions on how to access this AWESOME resource!
