Where to begin in ACS? Try a division, or two!

What does being a member of the American Chemical Society mean to you? For some, it’s a chance to stay connected to worldclass science and scientists. For others, it’s a platform to lead, mentor, and shape the future of the chemistry enterprise. Whether you’re an undergraduate exploring which branch of chemistry excites you most or a midcareer professional preparing for expanded responsibility, engagement in ACS is one of your most valuable resources. But in a large, global organization, how do you find your place? The answer is simple: divisions.With nearly 100,000 members worldwide, ACS reflects the full breadth of the chemical sciences. Its 32 divisions create focused communities organized around technical disciplines, professional interests, and emerging fields. For more than a century, these divisions have provided spaces for collaboration, research dissemination, leadership development, and recognition. They allow members to tailor their ACS experience to align with their scientific passions and career goals.Divisions span the entire chemical landscape—from foundational areas such as organic, analytical, and physical chemistry to communities centered on chemical education, professional advancement, and business development. This breadth enables members to deepen expertise within a discipline while also exploring interdisciplinary areas, all without leaving the society or rebuilding networks elsewhere. As scientific challenges increasingly demand crossdisciplinary collaborations, divisions work together to design joint programming and shared initiatives that reflect the evolving nature of the field.Beyond technical content, divisions offer substantial professional value. Members can get involved by organizing symposia, serving on executive committees, or contributing to newsletters and digital
