In this episode of Medsider Radio, we sat down with Deanna Harshbarger, CEO of Cala Health.

Cala Health developed the Cala kIQ® System, a prescription wearable therapy for action hand tremor.

Deanna holds a degree in chemical engineering and brings more than 20 years of commercial medtech experience to Cala. Before joining the company, she held senior leadership roles at Johnson & Johnson, Boston Scientific, and Medtronic, and helped develop and commercialize technologies across interventional cardiology, neuromodulation, and diabetes care.

In this conversation, Deanna shares how she empowers leadership teams to execute, building clinical evidence step-by-step, how patient observation shapes product development, and why raising capital is both a sprint and a marathon.
