Why CSNN Mississauga ?

“While being on a personal health journey I have ended up on the doorsteps of the Mississauga CSNN campus. After meeting with the College Director Carolyn-May I knew right away that this was where I suppose to be. Her passion, love, and commitment to the natural nutrition field shined clearly. I was inspired on the spot and wanted to be part of this amazing tribe of wellness warriors. I started part-time and then moved onto the full-time program which was amazing. I truly enjoyed my time at the Mississauga campus. The teachers were knowledgeable and helpful plus the practicums and the case studies took the information we learned to the next level. This program has been life-changing for me and I can’t say enough about the Mississauga CSNN. Thank-you!”
