My son Timothy has been with Roger Krahl for 8 years. Sensei Krahl has been a phenomenal influence in my son’s life. Roger has helped developed him into the young man that he is today. Roger Krahl has been a great mentor, teacher, and motivator. Because of what has been learned, Timothy is confident, focused and has developed great leadership skills. This is one of the best investments I have ever made. ATT Sunrise is more than a your traditional mixed martial arts dojo…..WE ARE A FAMILY!
