The All Breed Dog Grooming Guide - 4th edition

As the former owner and director of the New York School of Dog Grooming for more than thirty five years, he has educated, in the art of professional dog grooming, over 10,000 graduates, and countless others who have read the previous three editions of this book.

Mr. Kohl was the Director of the New York School of Dog Grooming from 1965 to 2000, and has been active in all phases of the pet industry since 1949. He has been a member of the Board of Directors of the National Association of the Pet Industry, the American Dog Groomers Guild, Ltd., and the International Dog Education Association in Japan.

Mr. Kohl judged the very first national dog grooming contest in the United States. He represented the grooming industry on the New York City Board of Education Animal Advisory Commission.

In 2011, Mr. Kohl was the first recipient of Barkleigh's Sally Liddick Lifetime Achievement Award for his many years of contribution to the grooming industry.

Working with the students and the grooming equipment available at that time made him acutely aware of the lack of tools that would facilitate peak performance. When he was unable to convince existing grooming tool manufacturers of the need for improvement, he turned to designing himself. He established the Aaronco Pet Products company in 1987, designing and manufacturing innovative tools to improve the labor-intensive grooming process.
