Our Philosophy

Our innovative educators bring passion and creativity to their teaching and aren’t afraid to do things differently. Most of our students come from schools that were not structured to enable them to succeed. We believe that with the right mix of challenge and support, young people who have left school can get back on the path to college, and at CUNY Prep, we make sure they do.

    Frantz Barbier, a math teacher at CUNY Prep since 2004, prides himself on helping math-phobic students over their greatest hurdles.

    Barbier was born and raised in the northeast Bronx, where he lives with his wife and young daughter. He holds a bachelor of arts in English language arts and elementary education from Hunter College.

  • Ngoc Duong

    CUNY Prep math teacher Ngoc Duong believes that math should be a hands-on learning experience with real-world relevant concepts.

    “My top priority is to create a positive classroom environment where students will be confident to use mathematical language to explain their work and to assist their peers,” says Duong. “I want them to realize that learning math is not only about solving problems but also about applying it in their real lives.”

    Duong, an immigrant from Vietnam, graduated from Hunter College with a BA/MA in Adolescent Mathematics Education. She joined the CUNY Prep teaching staff in the fall of 2014, and says she is sold on the schools college-bound focus.

    College Success Coach

  • Trevor Crest

    Social Studies Teacher

    Trevor Crest is the newest member of the CUNY Prep team and has taught in both public and private schools. He began his teaching career in San Diego, California where he taught visual art and painted a 110 foot mural with his students. He moved to New York in 2013 and plans to continue that trend by adding another mural to the list with CUNY Prep students via his visual art seminar.

    Mr. Crest’s main goal for his students is for them to become critical thinkers. “Simply taking the information your teachers give you is not enough. Question everything! With the amount of information available to us on a constant basis, one has to distinguish between what is valuable, entertaining, or otherwise simply fluff,” says Mr. Crest. Working with high school students allows for group discussions that have a base in real world experiences. CUNY Prep students are able to tie in their life experiences and identify how it relates to the content. Whenever this connection is made, Mr. Crest feels confident he has helped shift their perspective from local to global.

    Crest has a degree in both history and art from McDaniel College in Maryland where he played soccer and was the captain of the track and Field Team. Besides teaching full time, he has also coached wrestling, soccer and track.
