S5E2 - Living with a rare blood clotting disorder, Hemophilia C: an interview with Joseph Bautista
07 May 2024
00:14:08
Welcome to Ask Stago, the Podcast dedicated to provide expert answers to your expert questions in coagulation.
This month we meet Joseph Bautista, is a 37 year old US man living with a rare clotting disorder, a Factor XI deficiency otherwise known as Hemophilia C. His journey so far has not been an easy one but by educating himself and advocating for the best care he is living a full and healthy life working as a data architect in the IT sector. Its an inspiring and reassuring story for anyone facing a rare bleeding disorder diagnosis & proves the importance of patient empowerment.
