Amy’s relationships with U.S. EPA technical leadership and with national industry stakeholder groups are a great example of her living our vision. Amy will be an integral part of our ongoing legacy planning efforts that seek to transfer high level technical knowledge from senior staff to the entire team, an effort that we are also focused on with clients to provide similar assistance within their environmental teams. We are very excited to welcome her to the team.” said Colin McCall, ALL4’s CTO and Senior Consultant.
