## Overview

**Name:** Frank Rosenthal


## Bio

Frank Rosenthal was born on October 12, 1990, in New City, New York, United States of America.

Rosenthal’s interest in grappling started during high-school, a curiosity that led Frank to enroll in the East Stroudsburg University’s wrestling team when he attended the school to study Physical Education. It was also around that same time that his good friend Eric Sherman, a jiu-jitsu blue belt, showed Rosenthal an armbar, sparking the New Yorker’s curiosity for BJJ.

After his graduation from ESU (2013), Frank returned to New York where he joined the jiu-jitsu class of a Renzo Gracie Academy affiliate led by coach Carl Massaro, the man who would promote Rosenthal all the way to brown belt.

While looking to grow as a professional grappling competitor, Rosenthal sought to train with a range of coaches within the RGA network, finding in Doug Pelinkovic and John Danaher, two of his mentors. His development also presented Frank with a coaching opportunity, an activity he started at the Renzo Gracie Bayside (RGA affiliate) as a brown belt.

Frank’s outstanding work as an athlete and coach would facilitate his promotion to black belt on September 24, 2018. A ceremony attended by Renzo Gracie, John Danaher, and Doug Pelinkovic.
