Rees Machtemes began training at Black Belt of Karate in Calgary in September 2005, and was promoted to Cho Dan in 2009. He is currently a 3rd degree black belt in Tang Soo Do. He is fiercely loyal to the Moo Duk Kwan Tang Soo Do style and believes he has been extraordinarily lucky to have found this martial art in Calgary.

He began instructing, under the encouragement of his Master instructor Carl C. Tate, Jr. as a senior red belt and has continued teaching ever since. He has taught lessons at Black Belt of Karate Dojang, the former Heritage Stn. YMCA, and now continues teaching at Black Belt Academy.

Master Shelly Iverson was one of Grand Master Carl Tate's first students at Black Belt of Karate in Calgary. Master Iverson was promoted to Cho Dan in 2003 as part of the first-ever Tang Soo Do Dan ranking test in Calgary, Alberta, Canada. She actively trained at the Black Belt of Karate school until the BBK closed in November 2013, at which time Master Iverson decided to open her own school, the Black Belt Academy.

"My son and I were Grand Master Tate's first students back in 2001 and I love the art as much today as the first day I started. For me it's about the people I meet and sharing the art no matter what your capabilities are, or your age. Have Fun!"
