## Overview

**Name:** Frank Rosenthal


## Bio

A New York native who came to jiu-jitsu through high school wrestling and a friend’s armbar demo, Frank Rosenthal earned his black belt from Carl Massaro in 2018 under the watch of Renzo Gracie, John Danaher, and Doug Pelinkovic. His competitive development was shaped by training across the Renzo Gracie Academy network, and he began coaching at the Renzo Gracie Bayside affiliate while still a brown belt. Rosenthal’s path—from East Stroudsburg University wrestler to Danaher-influenced grappler—reflects the modern RGA pipeline where teaching and competing run in parallel.
