This week I had the distinct pleasure of visiting with Mark Washko, Head of Federal Government Affairs at BASF Corporation. I have worked with Mark and admire his extraordinary communication skills, particularly his ability to advocate on complex science policy and chemical issues clearly and in a way that is relatable. We in the chemical community are constantly challenged on so many levels in this regard — how to speak clearly, and to speak in a way that wins friends and influences those many who do not share our perspective, and how to remain respectful when addressing issues we care deeply about. Mark is top notch in these areas, and our conversation offers some lessons in effective government advocacy. We discuss Mark’s winning style, his approach to Members and staff on Capitol Hill, what prepared him best for his role, and his advice to those thinking about embarking on a career in government affairs.
