Our mission

We strive to help our clients conceive, develop, and design content that meets the highest standards of intellectual, editorial, and visual integrity.

We also endeavor to create a collaborative workplace where world-class editorial, graphic design, and video experts feel valued and can do their best work.

What we believe in
Separate from the pack

Why we’re different

We’ve been creating content for DECADES

Before content was a buzzword, we worked for and with thought leaders from leading organizations such as the McKinsey Quarterly, Deloitte, and Smithsonian magazine to bring ideas to life. Content is our lives’ work.

We excel at SIMPLIFYING the complex

We take complex topics and transform them into compelling, narrative-driven stories. Our industry experience ranges from technology and cybersecurity to healthcare and financial services.

We know what GOOD looks like

At Leff, we are more than a little obsessed with quality. We take an audience-first approach and pair it with razor-sharp logic to create compelling narratives and design.

We take the pain out of creating GREAT content

Our proven processes provide the structure and transparency you need to set expectations about the resources and time required for success. And we deliver on time and on budget.

We PERSIST until it’s great

There’s always a way. Give us your raw data and research, your rough drafts and abstract concepts, and we will work to exceed your expectations. We do what we say we’re going to do, ask a lot of questions, and push back when necessary in our relentless pursuit of quality.

Let's work together
Meet Leff

Our team

We work hard for our clients and we work together, and we think that shines through in the final product. If you walk into Leff you’re sure to hear the clicks from our keyboards, a lot of laughter, and the crackle of vinyl. And if it’s happy hour, the clink of a glass or two.
