About Our Team

Our core i-Human Patients team comes from a diverse background of technologists, artists, serial entrepreneurs and healthcare professionals.

We work closely with leading healthcare professional educators – both customers and advisors. Many of them have been instrumental in developing the forward-thinking ideas and concepts behind our products and services.

Despite our varied backgrounds, we are bound together by our shared passion for making high quality healthcare accessible and affordable to all – specifically by enabling active e-learning to promote the delivery of high quality, cost-effective care, and to ensure an adequate supply of healthcare providers fully trained in diagnostic reasoning. You’ll find our team members in North America and India today, and eventually wherever there is a need for better healthcare.
