Aaron Johnston, VP of Safety, Quality and Environment, only has on his environmental hat for this conversation on the role of habitat and endangered species stewardship in aggregate mining.

He talks about Graniterock's commitment to protecting and nurturing the endangered red-legged frog among other topics.

You'll also hear Aaron's personal story on how he came to Graniterock more than 25 years ago and convinced the late Bruce Woolpert he needed a dedicated environmental expert on the team.
