Mark Tremblay is the featured guest on the Rogers TV program “Trailblazers” this week. The episode, that premiers tonight (Sunday September 25), can also be seen Tuesday at noon, and Saturday at 10:30 pm, and again later in the season as a rerun. Trailblazers is a 30 minute, weekly program of conversations with local individuals effecting change in our community and around the world. Instead of being daunted by the scale of the challenge, one step at a time, one conversation at a time…these intriguing citizens are shaking and influencing their world. Rogers TV is channel 22 in the Ottawa area.
