I started my martial arts training in Tae Kwon Do in 1987. I received my Black Belt two years later in 1989 and then stopped training to pursue my college degree in criminal justice. I graduated from Wayne State University in 1992 with a Bachelor of Science.
I started training again in Tang Soo Do and began teaching two nights a week. I received my 2nd Degree Black Belt in March of 1993 and was offered a position as instructor at a full time school.
I started to compete in tournaments in 1994 and was ranked #1 in weapons in the State of Michigan 1995. (MKC)
In January 1996, I began training under Michael Bernardo for the national tournament circuit (NASKA) which includes the United States,Mexico,Guatemala, and Canada. I finished 10th in weapons. (NASKA) In October of 1996 I created the Karate and Fitness Center.

In 2003, I worked hundreds of hours to improve the teaching methodology and system within Karate and Fitness Center. In October I unveiled this new system to many of the students delight. This teaching methodology is still in place today and has helped the school grow into a major education center for people of all ages. In December, I was awarded my San Dan (3rd Degree Black Belt).
2004 through 2006 was spent studying child development. I spent thousands of hours creating programs to help parents. These programs include the Black Belt Parenting or Inner Circle Program - This 12 month program gives parents a complete education on successful parenting skills, and The 7 Worst Things Good Parents Do Seminar – this program discusses in complete detail the most common problems parents face with their children, and explains techniques and methods for correcting those problems.
In July 2006, I began working with Keith Hafner. Master Hafner runs one of the most successful child development schools in North America with over 800 students. The purpose was to improve “HOW” we teach and to learn better ways to communicate, motivate, and encourage students to be successful.
November 2006 saw the start of the “Annual Turkey Brigade”. I wanted to help local families in need and teach the children about community service. The Turkey Brigade was the perfect solution. 20 families received a complete turkey dinner for the holiday. Students put the food together in a basket and delivered each basket to the family. The plan is to grow this program each year until the students are helping hundreds of families each year.
