I Help Struggling Writers

Schools will teach students how to formulate a paragraph, respond to literature, and write a persuasive essay, but they will neither teach students the art of writing nor grammar.

This is where I come in.

I got through high school with an 88 average, graduated from college with a 3.4 GPA, and finished my first and second masters with a 3.75 GPA and 3.95 GPA, respectively.

And still, I was not an excellent writer.

I decided to study writing itself.

I retook the SAT and scored in the top 99 percentile of the SAT Writing Section, and I worked in Korean afterschool centers from Flushing to Syossett—Kent Prep, Brown Academy, and GEM.

I published a non-fiction book, a grammar book, and a children’s book and became the number one writing tutor in New York City.

This fall, the first batch of students I started tutoring in middle school will be starting college in Ivy League schools such as Brown and Cornell.

I became a good writer and I can help your children become good writers too.

Can Your Child Write?

If not, I can help.

I teach students how to plan, write, and proofread an essay.

I teach students methods, skills, and rules of writing.

What I teach will be used throughout your child’s life and possibly through the lives of your grandchildren.

I had help from great teachers, and I supplemented that education with my own self-education in art of writing.

I can teach your child how to write well too.

The college essay is not an essay; it’s a story. Start with an intense situation, describe who you are, and explain how you resolved your situation. My students have been accepted to world-class universities such as NYU and Columbia.

Testimonials

Before I met Mr. John, I was scoring in the high 400’s in SAT Writing and low 500’s in the SAT Reading. After working with him for months, I scored a 690 on the SAT Reading and a 710 on the SAT Writing.
— Hansung, CUNY Baruch
Mr. Castellano tutored me three weeks before the ACT because I was unsure of my skills on the English section of the test. The results: my initial practice scores of 24, 29 and 8 on the writing, reading and essay section rose to a 31, 34, and 10, respectively, on the official exam.
— Kyle, NYU Shanghai
Mr. Castellano is a reliable mentor and an incredible source of motivation. He taught me to step out of my comfort zone and to explore the world around me. He pushed me to own my strengths and accept my weaknesses. He sees potential in all of his students and the helps them strive to be the best they can be.
— Alyssa, Student, St. John's University
Mr. Castellano helped me get a precious scholarship that allowed me to study in internationally renowned Mathematical Sciences Research Institute (MSRI) in Berkeley, CA.

What I Do

In addition to being a high school teacher, I’ve worked in test prep centers - Kent Prep in Bayside, G.E.M. in Syosset, Brown Academy in GreatNeck. I’ve prepped students for the SHSAT, SAT, and ACT, and I’ve helped students write term papers and college essays.

If you needed my help before, you’d call the center, and the center would call me. Now that I’m independent, you can call, text, or email me directly.

My SAT Writing Score

I always wanted to tutor students to excel on the SAT, but not many schools gave me the opportunity to do so. Dedicated to standing out in the job market, I studied for the SAT and took it again. My score in the writing score alone nearly equalled my entire SAT in high school.

 

20+

Years Teaching HS English

I’ve taught every grade level in high school, special education, ESL, and AP. I’ve also hosted the last 13 graduations, qualified as a model teacher, attained a level two interview for the English AP job, and written two books.

Students in Ivy League Schools

I may not be the reason that these Ivy League schools, but I did tutor them. All credit goes to their hard work and their parents for emphasizing the importance of education.
