Grades 6-8 Teachers

Jake Devereaux

6th Grade Homeroom, Social Studies Teacher

I graduated from Brandeis University with a Bachelor of Arts Degree majoring in history and political science. I also attended Fitchburg State University where I earned a Masters of Education Degree. I most recently had the pleasure of being part of the History Department at Newton South High School. Prior to this experience, I moved to Washington D.C. and worked in variety of positions, inincluding at George Washington’s Mount Vernon Estate, where I was able to teach history in one of the most interactive and immersive environments possible. Although I do not dress in costume as often while teaching, I bring that same passion, enthusiasm and ability to bring history alive to my student at Our Lady’s Academy.

Patricia Fothergill

Hello, I am Patricia Fothergill. My husband and I live nearby in Arlington. We are blessed with one child, Katherine. I teach seventh and eighth grade math at Our Lady’s Academy, and have been here since 2008. I came to OLA after completing my undergraduate and graduate degrees at Boston College.I believe it is important to educate the whole child. Focusing on academic, social, and the developmental needs of each individual student. I love sports, and always find a way to incorporate into my classroom.

Kate O'Brien

7th Grade Homeroom, Science Teacher

I was an Our Lady’s parent for the past nine years, and I am excited to now serve as the Middle School Science Teacher.  After 20+ years performing a variety of roles in the energy industry, I obtained my Massachusetts teaching license in 2018 and worked as a long-term (7-months) sub at a public middle school in Westwood, MA.  I have a Bachelor’s degree from the University of Notre Dame, an MBA from Boston College, and a certification in Leading Innovative Change from UC Berkeley.  I live in Waltham with my husband and two daughters.  Together we love to travel and cheer on the local sports teams.  I look forward to working with the OLA students to help them prepare for life beyond Middle School!

Patrick O'Brien

8th Grade Homeroom, ELA Teacher

I grew up in Massachusetts, graduating from BC High in 2008. I have a bachelors degree in English from Wesleyan University and a masters degree in education and instructional technology from UMass Boston. I have always had a passion for reading and writing, and I try to bring that passion into the classroom. My classes focus on writing and grammar, with an emphasis on creativity and critical thinking. My goal is help every student develop his or her own unique voice as a writer.

Sarah Treacy

6th Grade Homeroom, Reading and Math Teacher

My name is Sarah Treacy, and I am a sixth grade teacher at Our Lady’s. After years of being a practicing attorney, I decided to follow my passion and become an educator. I left the law, completed my Masters in Education, and began my career at the school I happily call home – Our Lady’s Academy. I love being in the classroom, and am grateful for the privilege and responsibility I have each day to impact your children’s lives.

My husband and I live in Newton and we are the proud parents of two children. When I am not at school, I enjoy reading, walking my golden retriever Murphy, and scouting out new Young Adult literature for my students!
