In 1976, Kosslow Sensei moved to Atlanta so that he might attend graduate school at the University of Georgia. Between 1978 and 1983 Kosslow Sensei earned a Masters Degree, Specialist Degree, and Doctorate Degree in Educational Administration. He worked for the Fulton County Board of Education in Atlanta, first as an Elementary School Teacher (9 years) and then as an Elementary School Principal (17 years). In July of 2000, Dr. Kosslow retired from that school system.
In 1969 and again in 1975, Kosslow Sensei was fortunate enough to have been able to receive instruction from the late Otsuka Hironori Sensei, the founder of Wado Ryu karate-do. In 1985, he traveled to Japan for the 50th Wado Ryu World Championships as a member of the U.S. Eastern Team. In the early 1980's, Kosslow Sensei began training under the supervision of Suzuki Tatsuo Sensei, the most senior of all Wado Ryu instructors. When Suzuki Sensei created the Wado International Karate-Do Federation, Kosslow Sensei formally joined that organization in 1989. Suzuki Sensei has been his instructor since that time. Kosslow Sensei returned to Japan again in 1995 as a member of the WIKF Team to compete in an International Friendship Tournament. In 2003, he once again visited Japan to train and tour as a member of a WIKF world group.
In 2005, at the Wado World Cup in Plano, Texas, Suzuki Sensei promoted Kosslow Sensei to the rank of 7th degree black belt. This promotion made him the highest ranked WIKF teacher in the United States.
Dr. Kosslow served as the Chairman of the WIKF USA Board of Directors until December of 2006. He is currently the Secretary and a member of the Technical Committee of that organization. He has also served as a member of the Board of Directors for the Georgia Karate League since its inception in 1996. Dr. Kosslow has owned and operated the Newnan Karate Center in Newnan, Georgia since 1977.
