Sifu Collin Liebermen

Director & Head Instructor

Collin moved to Ithaca in 2012 and fell in love with the city that he now calls home. This move offered a life-changing opportunity for him - to transform his passion for fitness & martial arts into a full-time venture, providing exceptional martial arts & fitness training to hundreds of families in our community.

Collin personally teaches for most of Centerline's programs, including Adult Martial Arts, Fitness and Kids Kung Fu.

20 Years in the Martial Arts...

As a teenager, Collin was inspired by the writings of Bruce Lee and blasted into martial arts training, never looking back. Flash forward more than 20 years and he is a school owner and certified Full Instructor in Bruce Lee's art (Jun Fan Jeet Kune Do) under Sifu Raffi Derderian. Collin is also a Red Sash in the art of Kuntao Silat DeThouars, having been introduced to one of the finest Kung Fu & Silat instructors in the country (Sifu Matthew Cohen) while on one of his trips to train at the renowned JKD Inosanto Academy in Santa Monica, CA. Additionally, Collin has cross trained in many martial arts styles, including Taijiquan (with world champion Stephen Watson), Filipino Kali, Muay Thai, Western Boxing, and Brazilian Jiu Jitsu. The result of all this... a deep respect for those who undertake the journey of the martial artist - one of endless self discovery and improvement.

A Fire for Fitness and Movement...

Collin was an NSCA Certified Strength and Conditioning Specialist from 2012-2016, and continues to enrich his fitness education through various classes, workouts & workshops. In addition to founding the Kung Fu Strength and Skip 2 Ripped programs, Collin has experience with Kettlebells, Original Strength, CrossFit, Pilates, Forrest Yoga, Qi Gong, and Neigong.
