Work & talks

Behavioral science
in practice.

At maslansky + partners, I help teams understand what people hear when a brand speaks. These talks explore how that work plays out in research, pricing and everyday choices.

My story

It started with
my own habits.

At sixteen, I weighed over 300 pounds. Losing more than 100 left me curious about what makes a new habit stick. That question took me into exercise science, then consumer research, and eventually language strategy.

Today I’m a senior vice president at maslansky + partners in New York. I still take some of my best questions out for a run.
