| My name is Cal Siemens. I was born in the city of Kingston, Ontario, on Dec 11, 1997. My first school was Sydenham Public School, where I stayed for grades 1-6. I then went to the Challenge Program at Calvin Park Public School in Kingston, Ontario. I enjoy many sports like hockey, soccer, basketball, waterskiing, and downhill skiing. I also do other activities like karate (I am a brown belt) and guitar. I like to go on trips, and last year (2009) I went to Australia and the South Pacific. I plan to go to a university and may pursue a career in medicine. |
