While volunteering in a local hospital, I've noticed two scenarios:

  1. Children's discomfort during routine medical check-ups

  2. Parents were often ill-equipped to support their child in the clinic

Therefore, down the rabbit hole I went (pun intended), to find a solution by applying design-thinking, product development skills with extensive user interviews, and visitations to manufacturers and hospitals, to bootstrap the vision into fruition. It took 4 years of research and development to create a safe and comprehensive product before launching it in the USA. 

Rabbit Ray was borne out of the efforts to move from 1 to 1 (bedside volunteer to each child) to reach 1 to many children by equipping healthcare professionals and parents around the world. If you like Rabbit Ray and Joytingle's vision, please reach out and let me know how you would like to be part of it.
