It's only my 2nd day here but I'm already loving it, the girls are NOT snotty or limited to one group at all, everyones so family like and willing to become friends with you. I think what really made me like this school more is the fact i DIDN'T make the cheerleading team. I opened my eyes to all of the cool clubs that almost everyone can get a club they like. I made some really good friends already and i'm looking forward to making more. But on a side note, some of the teachers are EXTREMELY strict when it comes to some classroom rules. A girl was late on the first day, and when asked why she just explained that she got lost and the teacher said that it wasn't an excuse. It was the 1ST DAY!! You just have to know your teachers rules and remember every teacher is different with how they handle things. Goodluck and you'll love it here!

As parents, we feel the school admisinstration does a poor job as advocates for their students.Our son worked extremely hard 4 years in their honors program and is a member of the National Honor Society.2 days before graduation, he was denied the right to display his hard work to peers and family and was almost denied the right to walk at graduation because of a medical emergency that prohibited from attending his Sr sendoff.We had spoken to the administration about the situation and my son went to the school the following morning to explain what had happened.He was advised to write a letter of apology for not getting on the bus to attend the Sr sendoff. Saturday morning we were told he was permitted to walk but they would not allow him to wear the Gold National Honor Society sash.We asked to speak to the school principal and were directed to contact the schools attorney.At the Graduation ceremony, they did not announce that he was a member of their honors program or that he was a member of the National Honor Society.This is our 3rd child that has attended the school but will be our last.This school has let us down. I'm pretty sure that this in not what JESUS would do.

As a parent, I wanted to send my child to a school where they will be cared for and prepared for college. After much research, I saw that many Catholic schools are all preaching the same thing: "best 4 years of my life", "one big family here". All of that is great, but the statistics are more important. After talking to there admistration, I found out that Kellenberg's SAT scores are quite higher than the state average. With over 1/3 of the school scoring 400+ points higher than the NY average, I was immensely impressed. I also was told that the other two thirds of the school score around 200+ points higher.These statistics prove that Kellenberg is truly an exceptional school. I also was impressed with the amount of schlarships given, another great quality of KMHS. The school promotes discipline and working hard which I like. After making the decision on sending my son to Kellenberg, I have been truly impressed with the academics. They are VERY challenging, and quite harder than my daughters public school work and my son's work in Trinity.(he wasn't accepted into KMHS).After all, I have been very impressed with the school and look to send my youngest there.

Kellenbergs such a good school! For all of you looking up reviews because I know the chsee or COOP is coming up but it's not bad at all. I attended the open house a year ago and thought "how scary this school?!" but i love it. i'm so glad my parents pushed me to go here. At first I hated it. It's school. But i think going to a catholic grammer school helped since friends that use to go to public school of mine were struggling a lot with the rules. I was personally so scared to even move in class or talk to anyone but i joined activities and got use to it and remember all these kids around you are thinking the same thing so don't sweat it. My brother and sister both went to this school and they loved it so don't worry and lastly I want to say i'm so happy i didn't go to Holy Trinity because if i did I probably wouldn't be doing as good as i am now. GOOD LUCK EVERYONE AND COME TO KELLENBERG. THE BIGGEST TIP IS TO GET INVOLVED!!! all the other reviews are from people who probably didn't get involved or did horrible in school but just keep up your studies and join activities!

Kellenberg is an amazing school. The teachers are excellent and the academics are outstanding. The students are so friendly and welcoming. Kellenberg is the best catholic high school on Long Island!

Posted September 4, 2013

Kellenberg is superb! The teachers are total professional, but it is crystal clear that they TRULY care about their students as well. My third child just started today and he loves it. While it is very challenging academically, every teacher my children have had have made themselves easily and abundantly available. My oldest is doing extremely well in college now and I credit Kellenberg for preparing her so well. If you are a troublemaker, this is probably not the school for you, as it will not be tolerated. As a parent of kids who don't get in trouble, Im thrilled the tolerance level for those who do is very low. My children LOVE Kellenberg, as do I. I feel the faculty and staff treat the students with great respect and live in a Christ-like manner. Well done, Kellenberg!

Kellenberg has been a dream come true for me :). I have had quite a different experiencefrom the girl below me. I came from a not so good district where bullying was highly apparen't and the academics were poor. I needed a place to go where I can be the best and kellenberg really did that for me. The academics are challenging and the school is very disciplined. The deans are very strict and enforce every rule. The comps or finals were very challenging. Each one had like 300 questions and many essays with each one. This realllly prepares for colllege. Just look at where the students go when they graduate. they attend these great university's on big scholarships too. Another reason I went to kmhs! As for the students. I found them very open and kind. I'd say only 1% of the school is that typical snobby rich kid type. The other 99% were cool, kind and really friendly. Its really easy to make friends here. I love this school and the clubs and sports and friends here!! :)

I started out freshman year at Kellenberg. I was so excited to attend this school because I was going to be in the Honors track. I was looking forward to making new friends and trying new activities. A couple of days into the school year I started thinking "What did I get myself into?" Most of the girls were very snotty, definitely not family like. I faced some of the worst experiences of my life at Kellenberg. Finally after a couple of months of begging my parents to let me switch schools, they did. Sometimes I think maybe I was doing something wrong, but this school DEFINITELY does not live up to it's high status. I didn't find that the teachers cared about us individually, except for one. I wish that Kellenberg was all I expected it to be, and I'm incredibly sad that it wasn't.

Kellenberg Memorial High School is an absolutely incredible place. Kellenberg has solid academics and excellent sports and activities. Kellenberg's stunning campus features all artifical-turf fields, three breathtaking courtyards lined with fish ponds,four chapels,and wonderful science and computer rooms. cant wait to start Junior year, the kids at Kellenberg are the most friendly,helpful student body found anywhere. (a known characteristic of the school) But Kellenberg is not for everyone, Kellenberg is very demanding and the classes are very challenging, If you are driven to succeed and have a desire to learn you'll love this school. But It all pays off, every year the graduating class receives over 2,000 scholarships and grants, and consistently over 99.6% of the graduates will head to college. Kellenberg is like one big family with some of the most outgoing teachers and faculty anywhere. I my self am very involved and don't want to leave at the end of the day. Talk to someone about it because just about everyone knows someone who goes to K-Berg. Kellenberg truly changed who I am as a person and so many graduates say "It's been the best four years of my entire life".

I had one of the worst experiences of my life at Kellenberg.the staff treated me unjustly and made false accusations about me. The punishments just started getting unreasonable and I ended up in detention every day.Everything proceeded to get worse and I started to get bullied. The staff basically promotes bullying.DONT GO HERE DON'T WASTE YOUR TIME AND MONEY PS I had to leave In the beginning of the year

As a recent alumni of this school, I can honestly say that this school helped to mold me into the person I am today. Regardless of the cliche nature of that statement, I have to give credit where credit is due. I am an English major at a university, and Kellenberg definitely fostered my love for English. I will adhere to previous complaints about the school and say that, yes, they are right when it comes to math and science. These departments are not the strong suit of the school, but it is working on strengthening those sections to be comparable to those of English and History. The teachers were so helpful, and the family aspect of the school was one that was so nurturing and necessary, especially as an awkward freshman going to Catholic school for the first time in her life. My parents have sent all three of their children there, and I think that says a lot about the school because I think every parent only wants the best for their kids. Overall, my experience at Kellenberg is something that I will never forget. I made friends that I know will be in my wedding, and I gained self knowledge that I know I definitely wouldn't have been able to gain had I gone to public school.

Save your money and spend what will be your four year aggregated tuition cost of $30,000 elsewhere. The education that this school claims to propound is wholly inconsistent with the education your child will actually receive. I mainly direct this statement, like the previous review, at the school's lack of preparation for a college education in math and science. At orientations and the like, the school administrators will tell you apocryphal anecdotes about how their alumni are overly prepared for college, when in reality, they're at a major disadvantage. As a first year science student at a university, I'm entirely unprepared for my lectures and labs, and virtually exempt from competitive research opportunities because of that fact. Mind you that all of this bares on my dream of becoming a doctor which is now not only grim but potentially unreachable. I will admit that they provide your child with a great English and history education, but that's about where they stop. They: don't offer AP credit (even public schools do), exalt a antiquated/fallacious curriculum, and are unwilling to compromise on any account. Bottom line, if your child has professional dreams-- avoid Kellenberg.

Posted April 6, 2012

If your child is interested in math or science or getting into an upper level college (any in the top 30), do not send them here. Kellenberg's lack of adequate preparation for college-level math and science courses is laughable. I have to say, Kellenberg did improve my writing immensely, but as for math skills, they were horrendous. I am a college student; my friends who went to public schools have a HUGE advantage over me in their knowledge and understanding of calculus, chemistry, and physics. Go look at a AP Chemistry, AP Biology, AP Physics, or AP Calculus test prep book. Kellenberg students learn roughly 1/2 of the total information. Plus, we NEVER DID A LAB. They will show you beautiful labs in a Kellenberg tour, but WE DID NOT USE THEM. I was in honors science for four years and I never had a dissection during class. My friends at other high schools who took AP sciences had at least 15 lab exercises during their year. I'm pretty sure I had two in Honors Chemistry. Completely ridiculous when my parents spent over $8,000 a year on my education. If I had AP credit in college, I could register for better classes earlier and even graduate early.

I hated Kellenberg Memorial High School when I attended. It was definately the worst four years of my life. I'm not a very religious person, but regardless, I could have adjusted better to the school environment if someone had reached out to help me. I have a social anxiety disorder that caused me to stand out from peers and consequently, caused me to be harrassed and teased by other students. I became very depressed because my mother was diagnosed with a disease, but nobody helped me. Sometimes, I felt like the faculty was also taking advantage of me there. I was so depressed because I thought the only way to make friends was to do what other people wanted me to do. I take responsibility for not standing up to myself, but I think the school and the faculty should have done more to help me. Only one teacher spoke to me about it, but that is not enough. The students are very obnoxious and think they are better than everyone else because they go to a private school. The education system is weak too because it limits the students' choice of electives and does not include an AP system for those who deserve it. I give this school a zero and do not recommend sending your children there.

SUCH A FAMILY HERE!! Its such a majestic enviorment for us ...students!! <3 Kellenberg. Their discipline is awesome and it really develops a person as a person !

Posted October 25, 2011

I would like to respond to a post made on June 8, 2011. The reviewer said that his/her child would not be attending Kellenberg because the student "will be deprived of taking ANY AP classes." The reviewer fails to mention that any student who demonstrates a mastery in certain academic subjects may elect to take the Advanced Placement Exam in that subject area. The honors level courses at Kellenberg meet or exceed the standards for AP; one difference, however, is that Kellenberg will not compromise its devotion to educating the whole student by "teaching to the test," which is often a strategy in courses labled "AP." I am speaking as a parent whose child is a student at Kellenberg, a graduate of Kellenberg, and an AP English instructor at a public school.

I love this school! The academic program is challenging and the teachers are young and enthusiastic. If you value your Catholic faith and discipline, this is the school for your child. If you don't value strict consequences for negative behavior then this is NOT the school for your child.

I have a child entering her third year at Kellenberg and one about to enter for 6th grade. I have been very pleased with the school thus far. My daughter has thrived there, the teachers are open and available, the extracurricular activities cover a very broad range of interests. I was anxious about their reaction when my daughter injured herself just before final exams last year. The administration could not have been more accomodating and concerned about making things as easy as possible for her. It truly impressed me that their general 'strict compliance with school rules/policy' was so quickly put aside to make sure that the 'whole child' was getting what was necessary. This school is certainly not for everyone. We like the emphasis on doing whatever it is that you do the best that you can. This school offers my children high goals, and the means to reach them. It also offers a varied ways to broaden a student, and encourages independence and strong social bonds.
