Jennifer Hack

Preschool Teacher

My name is Jennifer Hack, and I am the new preschool teacher at St. William School. Growing up, I had the privilege of receiving a Catholic education from Pre-K to 12th grade. I believe my strong beliefs and morals were shaped as a result of these experiences. I recently graduated from Northeastern Illinois University with a Bachelor’s degree in Early Childhood Education and a minor in Teaching English as a Second Language. I am truly honored to be a part of the St. William’s family and am looking forward to meeting/working with the students this year!


Sarah Welch

Kindergarten Teacher

Hello everyone! My name is Sarah Welch, and I am the Kindergarten teacher here at St. William School. This is my first year at St. William, and my first year teaching overall. Prior to teaching, I attended Saint Mary’s College of Notre Dame where I received my bachelor's degree in Elementary Education and a minor in both Early Childhood Education and Sociology. I could not be happier to be teaching at St. William School. The warm welcome I received from the families, students, and staff here was such a blessing to me as I made the transition to St. William. I am very excited to teach Kindergarten and for all the great families that I will encounter. Kindergarten is where my heart is and I am truly blessed to have the opportunity to help children learn and grow daily. I strive to create an environment that is positive, safe and inviting while providing many opportunities to develop new skills enabling the learning experience for every child in my classroom to flourish.

Welcome to first grade! My name is Madeleine O’Connor and I am excited to be teaching at St. William School. Prior to this I taught as a long-term preschool substitute teacher at St. Bartholomew. I am a recent graduate of Northern Illinois University with my Bachelor’s in Education. I have a deep appreciation for a Catholic education. I attended both Queen of all Saints for grade school and Resurrection College Prep for high school. I am very thankful for the opportunity to teach first grade and appreciate the warm welcome that I received. I am currently working to complete a Hernandez fellowship at the University of Notre Dame. My goal is to provide a learning environment that is welcoming, safe and positive. I want first graders to achieve their goals and have a successful school year!


Nicholas Spanuello

Second Grade

My name is Nick Spanuello, Mr. S, and I am proud to be joining the amazing team at St. William School as the new Second Grade Teacher of Little Superheroes.  For the last 13 years my job has been to make hundreds of children smile everyday, and I do not intend to stop now.  Kindness, compassion, faith and inclusiveness mixed with a good dose of math, reading, logic, and creativity will create a spark inside each student’s growing mind that will bring out each of their super powers. Each of us is capable of different skills, and some of us have capabilities we are not even aware of yet.  We all exist together as one team, one unit, one cohort.  Every person possesses a unique characteristic, something they can bring to the table that no one else can...In second grade this year, we are unlocking all of our abilities.

Meaghan Cohen

Third Grade

Hello! My name is Meaghan Cohen and I am the 3rd grade teacher at St. William School! I am honored to join a wonderful team and beyond excited to meet my new students! A little about me, I hold a Bachelor of Arts from Western Michigan University and am currently enrolled at Dominican on my way to a Masters of Education. I live in Elmwood Park and have 2 elementary aged boys who also attend St. William School. Relationships and trust are my foundation in teaching with a positive and encouraging mindset. As we all know, the start of this year will be a little different. With that being said, I am dedicated and passionate about making it a successful (and fun) transition back into school. Let’s learn and live to our fullest! 


Nicole Noverini

Fourth Grade

Hello!  My name is Nicole Noverini, and I am joyfully joining the St. William community this year.  Since earning a Bachelor's degree in elementary education from Elmhurst College, I have spent the past 15 years teaching and tutoring.  Over the years, I have worked with students in first through eighth grades at schools in the Diocese of Joliet and earned a Master's degree from North Central College in Educational Leadership.  I am a product of Catholic education and feel passionate about the opportunities offered through Catholic school experiences.  I feel blessed to have the opportunity to help the fourth grade students grow in faith, academics, and personal development.  Over the school year, I am most looking forward to getting to know the students and creating student-centered learning experiences for all.  When I am not teaching, you can find me reading, riding my bike, traveling, or with my husband and three kids.  Be blessed!


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 as well as learn how to be organized and responsible to each other and ourselves. Our day begins and ends with prayer. Our classroom will be a fun, exciting place to be as every day is a good day. I look forward to meeting all of you. 


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.

Sandy Frobel

Seventh Grade

My name is Sandy Frobel and I am the 7th grade homeroom teacher. I also teach Science and Math to the 8th grade students. This is my 27th year educating students at St. William School. My role is to help your child reach his or her potential. I am available to students and parents any time help is needed or for any questions and concerns. My goal is to create a safe and nurturing environment for students. I expect all students to come prepared for class and strive to do their best. It is necessary for all to be respectful of everyone in the school. When students are in doubt, I would encourage them to ask for help. Students are given homework regularly which is posted in the classroom and on Edmodo and expected to complete work on time. Again, a child's education and growth are very important. I want to see your child develop in both knowledge and faith and be prepared for their future years.

Martin Zaccaria

Eighth Grade

I’m Martin Zaccaria, and I am the 8th-grade teacher for St. William School. Prior to the 2019/2020 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. I am also currently seeking my Master’s in secondary education at DePaul. Although I am one of the newer teachers here, my family has been a part of the St. William parish for four 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. In P.E., our students work through an exercise routine and then participate in a variety of sports and activities including: baseball, basketball, football, handball, lacrosse, mediation, soccer, and volleyball. In the spring, we host our Kids’ Fitness Challenge & Keeping Kids Healthy day-long event in which students learn from experts how to make healthy choices and participate in a variety of physical activities. Our students not only learn how to play various sports, they practice valuable teamwork skills and learn healthy habits.
