Jamaica Plain's Sandy Gonzales recently participated in the Columbia Threadneedle Boston Triathlon while raising funds for Team BMC. Gonzales is one of 89 members of Team BMC all raising money for Boston Medical Center's Vision 2030, which is a new initiative to make Boston the healthiest urban population in the world through better medical care, eating habits and addiction treatment. Gonzales answered questions from Jamaica Plain News about her work at Boston Medical Center, training for her first triathlon, and what she'll be thinking about while she's running/swimming/biking. Q: What made you want to help people with substance use disorders? Gonzales: I am empathetic by nature and I was also raised to value the importance of helping people and making a positive impact in my community.
