Mrs. Helen Colletti

Fifth Grade

My name is Mrs. Colletti and I am the fifth grade homeroom teacher for St. William School. I also teach sixth grade math. My educational background includes a Bachelor of Arts degree from St. Xavier University and a Master of Education from Dominican University. I have taught various grades at St. William School and this has helped me to understand the skills that your children need as they advance through their elementary years. This year will be an adventure for your fifth grader as we learn many new things together. I believe that success happens when preparation meets with opportunity so we will do many challenging activities in our classroom as well as learn how to be organized and responsible to each other and ourselves. Our day begins and ends with prayer. I know when I walk through the school door that every day will be an interesting day. There is always a St. William surprise!

Mrs. Karen Zaccaria

Sixth Grade

Welcome to 6th grade with Mrs. Karen Zaccaria.  I also teach 5th grade social studies. My family has strong ties to the St. William Parish community with several generations of Zaccarias covering over 80 years.  Many of the Zaccarias have graduated from St. William School, including my husband and son.  The passion I have for teaching is just as strong today as it was when I first started teaching.  I have taught full-day kindergarten and first grade.  Teaching computer classes for kindergarten-8th and the school’s technology coordinator are another positions I held before my current teaching position as the 6th grade teacher.

        My teaching style combines a varied balance of experiences, from hands-on, peer teaching, project-based learning, individual and group work, and performance based assessments.  I do believe that students learn in various ways; thus, I provide opportunities for students to build on his/her strengths and develop skills that need support.

        I look forward to working with you and your child this school as a team.

Mr. Robert Serwa

Seventh Grade

My name is Robert (Bobby) Serwa and I am the 7th and 8th grade math and science teacher here at St. Willliam's. I am a new teacher this year but have been in education for 4 years. I have spent the past three years as an afterschool program coordinator in Evanston for primarily free and reduced lunch students. During the summers, I also helped run a summer camp for those same students across multiple schools in District 64 and 65. I love the warmth, comradery and helpful nature of the staff and students. The children have already taught me so much about how to be a better teacher and person. I love coming in everyday and finding something that makes me smile. I felt that St. William was a great school to learn and grow as an educator. I knew that there was a lot that I could do to give back to the Catholic school community and enrich the school day for the students I teach.I have many people that inspire me, but I think the person I most look up to for how to live my daily life if Bruce Lee. His philosophy of "Be Like Water" is an important part of how I want to be as a person. If you don't know this quote, you should absolutely look it up! My favorite things to do on the weekends are to spend time with my friends and family and support my friends playing in the Chicago music scene.I have hiked across the Grand Canyon (Rim to Rim) 3 times. Words really don't do justice to the majesty of that place.I'm always excited to learn more: whether it's about St William, the community, or different customs and cultures. Please feel free to share with me about any of these things!

Mr. Martin Zaccaria

Eighth Grade

I’m Martin Zaccaria, and I am the 8th-grade teacher for St. William School. Prior to the 2022/2023 school year, I was the Physical Education instructor for our pre-school through 8th-grade students. I earned my Bachelor’s in English Literature and Catholic Studies from DePaul University as well as my Master of Education in Secondary English. My family has been a part of the St. William parish for five generations. As a graduate of St. William, I love the fact that I can work at my old school and give back to the place and people that started my education. I believe in strong Catholic schools that not only teach our children solid academics, but also instill in them a faith in Jesus Christ and active participation in the Church. "Make no little plans. They have no magic to stir men’s blood and probably themselves will not be realized. Make big plans; aim high in hope and work, remembering that a noble, logical diagram once recorded will never die, but long after we are gone will be a living thing, asserting itself with ever-growing insistency. Remember that our sons and grandsons are going to do things that would stagger us. Let your watchword be order and your beacon beauty. Think big."--Daniel Burnham

Hello! I am Kareema Bass and I am the Title I Instructor here at St. William School. I have been teaching here since 2022 and have been in the field for 4 years! My previous roles were Preschool teacher and Morgan Park High School Service Learning Teacher. My favorite thing about St. Williams is the collaborative environment to provide quality education to the students of St. William. I came to St. Williams to make sure that every student has the resources they need to succeed. I believe that every child can succeed! It is my life's work to diligently to make sure that every student believes that they can succeed, as well as have the necessary tools to do so. The quote that I carry in my heart for every student's life that I touch is that "Learning isn't linear". My teaching depends on the learner and the situation. I believe that every day of life is a learning experience, which is why my classroom is student centered. I don't always have the answer, but I'm willing to be taught. The magical and transformational part of it all is that my students teach me every day how to be a better teacher for them.
