This year, our school Gardening Elective with Mr. Chilinski has made a remarkable impact by growing and donating over 100 pounds of fresh produce to the local food pantry and school community. Through our dedicated efforts, students have cultivated a variety of fruits and vegetables, including ...tomatoes, peppers, potatoes, carrots, cucumbers and an array of salad greens. All while learning the importance of community support through Catholic Social Teachings. The joy of seeing our hard work translate into nourishing meals for families in need has inspired us to continue expanding our garden and deepening our commitment to service. We are proud to contribute to the fight against food insecurity in our community and help those in need!

Our 8th Grade Volleyball teams have qualified for the Seton Volleyball Tournament!
What: Since 2006, the Elizabeth Seton Volleyball Championships has served as the largest 8th grade tournament in the Archdiocese of Milwaukee. The Seton is volleyball's equivalent to the Padre Serra ...basketball tournament, bringing together schools from 7 conferences throughout Southeastern Wisconsin. The invitation-only tournament consists of 3 divisions containing 68 total teams, including both "A" and "B" teams (48 girls teams in 2 divisions and 20 boys teams in a single division), competing in 156 matches over 7 days. The Seton is unlike any other tournament most players will experience in middle school, and it is a great way for the 8th graders to cap their school careers!
Where: Milwaukee Sting Center
When: Tonight at 5:30 PM (BOYS) & Tomorrow at 5:30 PM (GIRLS).
We would love for everyone to come out and support our students as they represent SJ23!

Meet School Resource Officer (SRO) Officer Bergin. Officer Bergin has been with the Port Washington Police Department for 24 years, full-time SRO for the past 4 years. Officer Bergin has trained through the National Association of School Resource Officers (NASRO), implementing the “triad” ...concept where responsibilities are divided amongst three areas: public safety educator, mentor/informal counselor, and law enforcement officer. The SRO assignment is unique within the law enforcement profession. Not only are they law enforcement officers, but they are also mentors, counselors and educators who work hard to create relationships with our youth, school officials, and parents to keep our schools safe. Officer Bergin is a valuable member of the PWPD and the Port Washington-Saukville School District & SJ23. The work he does in the schools is immeasurable!

As a project based learning opportunity for our Argument Unit, the 8th grade students were assigned to a role of Defense Attorney or Prosecuting Attorney in the case of the Narrator of Edgar Allan Poe's Tell Tale Heart. The teams were Assigned a Captain to lead their work. Each attorney was ...responsible for an essential element of the case: Intro, Body Paragraph, Counter Claim, and Conclusion. All essential elements were supported with evidence and analysis. Public speaking is an essential skill, and our students leave SJ23 well-prepared to excel in this area.
