The company we keep.

We work with people who care deeply about what they do and who they serve.
That part really matters to us.

We are proud to work alongside organizations doing meaningful work in the world around them, including groups such as:

Behind every meaningful partnership is a shared story.

Here’s what a few of our clients have to say about working with us.

ASTM International has benefitted from collaborating with Stacy Leistner and The TAGS Group on multiple occasions—most recently, the celebration of ASTM's 125th Anniversary. Our goal was to tell a story—to reflect on our past, celebrate our present, and create excitement for the future. We wished to share that story with our membership, customers, partners, and staff around the world. It was a tall task, and we knew exactly the team to help us—Stacy and The TAGS Group. Stacy listened, distilled our ideas, and coordinated our planning and execution process for a year-long series of initiatives and events. His years of experience brought new insights and energy that our team embraced. He kept us on point, aligned, and on schedule. Most importantly, Stacy helped us deliver a year of memories and hopes that captured and shared the culture and impacts of ASTM International. The ASTM community at large had a year to remember.

Stacy and The TAGS Group have been wonderful collaborators for more than a decade. They helped me and the Museum staff shape messages, celebrate milestone moments, introduce new digital tools, and connect with audiences in meaningful ways. From our fiftieth anniversary to everyday communications, Stacy and his team have always been thoughtful, creative, and reliable. They brought energy, insight, and a real understanding of the Museum and its mission to everything we worked on together.

The TAGS Group's work is truly woven into the fabric of Purchase College. Their contributions have been both meaningful and far-reaching, and the Purchase community will benefit from their creativity and dedication for years to come. The team has consistently demonstrated professionalism, thoughtfulness, and an enthusiasm that inspires those around them. I would be pleased to serve as a reference at any time, and I will confidently recommend their services to others in my network.
