Diagram is a New York City-based design studio dedicated to improving healthcare experiences and health outcomes by seeing through the eyes of the patient.

We gather and translate insights from patients and providers that create better and meaningful experiences. Our expertise is in creating behavior change, supporting adherence, and designing tools that help patients better manage their conditions.

We also make a mean smoothie.
