From surviving a mass shooting to going to space, some events in life are so impactful, they change everything. Before & After dives into the pivotal moments of our lives that forever change who we are, and how we see the world.

In Episode 1, Before & After: Cancer Diagnosis, we meet Tamara O'Brien. O'Brien was a 21-year-old gymnast on the Canadian National Team and had just earned a medal at the World Games. She was on her way to the World Championships when she discovered a lump on the left side of her neck. It was this lump that would turn O’Brien — the rising star athlete she always saw herself as — into a new person, someone she would have to get to know all over again.


Her diagnosis became a pivotal moment for O’Brien that would change her priorities and her perspective. On the anniversary of her diagnosis, she shared her vulnerable and intimate story in Before & After: Cancer Diagnosis. Tamara O'Brien sadly passed away on October 15, 2019.
