Our Senseis


Sensei Walter Miller began practicing judo at Yale Judo Club in 1969 after wrestling for five years.  At Yale, he won the state championships both times he entered in his respective belt and weight divisions under Sensei Insoo Hwang.  After college, he studied Japanese Ju-Jitsu and earned his black belt. He returned to judo as a white belt with his new sensei John Pereira. He competed for the Connecticut Travel Team in his thirties and placed second at the Connecticut State Championships with a black belt.  He has taught Ju-Jitsu and Judo ever since, including at his own dojo for several years.  Sensei Miller obtained his undergraduate degree from Yale in Psychology and his Masters in Social Work from UCONN.  Following retirement from a career as a clinical social worker with a specialty in addiction treatment, he moved to Morriston, Florida. He took over responsibilities as coach of the recently revived Gator Judo Club in November 2015. He holds a Sandan (3rd-degree black belt) in Judo and a Shichidan (7th-degree black belt) in Ju-Jitsu.
