Prom 2019

Prom will be held on Friday, April 26, at The Rosemont Convention Center.  The cost is $75 per person. Please note each student AND each guest will need to fill out their own permission form.   Due to reservation requirements, unfortunately we will not be able to offer refunds after April 19th.  Additionally, no refunds will be issued to students in the event of a disciplinary action or an attendance issue on the day of prom, which results in the student's inability to attend prom.

While tickets for the Prom itself are always available to any eligible CG student (as an individual) or with a date, sign up for our wildly popular (and safe) Post-Prom activity supported by our Booster Club is unfortunately limited.  We will be selling post-prom tickets on a first come and first served basis, prioritizing as many seniors as possible attending their last Prom and Post-Prom with us.  Below are the details of the process that allow for the aforementioned prioritization and also minimize attendance issues during the school day.  In the past four years, Post-Prom has NOT sold out; all students who wanted to, were able to attend this event.  

Beginning the evening of Tuesday, April 9 from 6 PM to 9 PM Cary-Grove High School Seniors only, may sign up for Prom and Post-Prom in the Media Center on this date.  Senior Cary-Grove students attending with another Senior Cary-Grove student will register from 6 PM until 7:30 PM, the Senior CG students attending with anyone other than a Cary-Grove senior student will register from 7:30 to 9:00 PM.   If arriving after 7:30 PM, any CG senior/CG senior must go to the back of the line.  

On the evening of Wednesday, April 10 from 6 PM to 8 PM any CG Junior and their date or CG Senior and their date (if they did not sign up on April 9) may sign up for Prom (and Post-Prom, until sold out).  On this date there will be no priority given to CG seniors.   Additional ticket sale dates are shown in the table below.

Prior to registration, all students and guests must EACH complete a permission form, have an online payment receipt or a check payable to CGHS, or cash along with all paperwork approved for guests.

Any change request to prom arrangements after the April 9 and 10 sale dates will require a $10 processing fee.

Crystal Lake South Students Qualify for National Business Competition

Crystal Lake South High School’s Virtual Enterprise, Unwind, will travel to New York City next month to participate in the National Business Plan Competition as part of the VEI Youth Business Summit. The group qualified for the event after they won first place at the Illinois Business Plan Competition in December.

Unwind was formed during the fall of 2017 and consists of 24 juniors and seniors. The goal of the company is to reduce stress and anxiety in high school students by selling a variety of products. Every student in the organization has specific job, including CEO, COO, CFO, and VP of Product Marketing.

“For all of us, Unwind has had a huge step in our development, not only as business minded individuals, but as leaders and people,” said Mariano Caballero,Crystal Lake South senior at Unwind.

At the Illinois State Business Plan Competition, the students had to write a 28-page business plan, pitch their company, and answer questions from a panel of judges who acted like potential investors.

The stakes will be even higher at the the National Competition. Unwind will compete against more than 30 firms for a $10,000 check.

“We are allowed and have worked to improve both our written and oral presentations of Unwind’s business plan,” said Caballero. “We really are working to stand out even more with what we’ve done since the state competition.”

The Unwind group is grateful for having the opportunity to explore the business world in the classroom and some students plan to continue their passion for business when they attend college in the fall.

“I am very excited and thankful for this opportunity in VEI. Who knows, maybe I’ll be a real CFO someday with the experience from this extraordinary organization,” said Julia Lavorata, Crystal Lake South senior.

The National Business Plan Competition takes place April 15 through April 17 in New York City.

Haber Oaks Campus Teacher Earns Teacher of the Month

​Tony Moretti, a teacher at Haber Oaks Campus, is the Star 105.5 and Home State Bank Teacher of the Month for January. He won the award after a former student, nominated him.

Mr. Moretti is a special education teacher at Haber Oaks and has been a part of District 155 for five years. In the nomination letter, he is described as “one of those teachers that genuinely want to see you succeed.”

“So many of our students come in feeling lost and it's our job to make them feel more comfortable in their own skin,” said Tony Moretti, “I think a lot of people don't realize we're a therapeutic day school and the social/emotional part is huge at HOC.  I feel like all the teachers, administration, paraprofessionals and service providers at Haber Oaks work so hard to make our students better citizens when they leave our school.”

The former student, who wrote the nomination letter, says Mr. Moretti helped her graduate from high school six months early and is the reason she went to college. Her touching letter about her path to success is the reason Star 105.5 and Home State Bank chose Mr. Moretti as the teacher of the month for January.

In addition to teaching, Moretti also coaches the Junior Varsity girls basketball and Junior Varsity softball teams at Crystal Lake South High School.
