Over the years of teaching the public, and in my numerous travels all over Asia and to South America I have trained members of the Military, Emergency unit departments, local Police departments, Park Ranger Police departments, County Sheriff departments, and various Members of Federal Departments, (examples Department of Justice, Immigration, etc.). I taught classes as a fill in teacher, later my own class at other peoples schools (example: The College of Martial Arts in Evanston, IL.) still later classes out of my home and out of dance halls, until finally schools where I bought the buildings and remodeled myself (2 in Round Lake IL. I have been hired by the individuals working in Police departments, sometimes by the department, and have been a guest instructor for criminology classes, and classes through High Schools, Colleges, and YMCA’s. I have in later years been hired many times to go teach two day or weekend Seminars and Workshops for various Schools, Police and other groups in the United States, in Asia and South America. I do not have photo's or documents from most and in the case of some military work I was not even supose to talk about it. But below are some letters of recognition and recomondations that I do have that can be shown.
The most important teaching I have done for me is the on going public classes in my schools. Those select few (maybe one out of a hundred) who actually continued for 4 -8 years of continuos classes to complete my course teachings, or through others to become Officers in the Schools or fully trained Black Belts.

These are a few of the referals/ letters of praise for Datu Guro Glen Dahms & students assisting in doing Demonstrations, Seminar/ Workshops, for Schools, Police Departments, Paramedic/ Rescue Departments, Airline Pilots and others!
