Sifu Collin Lieberman
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 martial arts & fitness into a full-time venture, providing exceptional 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 of Martial Arts...
As a teenager, Collin was inspired by martial arts legend and founder of Jeet Kune Do (JKD), Bruce Lee. At age 18, Collin discovered a JKD school near his hometown and wouldn't stop talking to his parents about it. They signed him up as a birthday gift shortly thereafter, and what a gift if was! Flash forward more than 20 years, and "Sifu" Collin now owns his own martial arts academy. He is a certified Senior 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 self 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 Centerline Kung Fu Strength and Kickboxing programs, Collin has experience with Kettlebells, Original Strength, CrossFit, Pilates, Forrest Yoga, Qi Gong, and Neigong.
