@jsnfltn After lots of time spent with Dr YouTube and Dr Google and sorting out the snake oil salesman I selected Dr Bruce Patterson and his team. There are lots of great YouTube videos posted by some wonderful groups of Doctors and Medical Journalists who are trying to help LC sufferers. Spend some time watching those to bring yourself up to speed on what's possible. Those same videos provide all of the contact information, but in Dr Patterson's case (providing the process has not changed since December 2024) it was a very simple step by step beginning with this website below. However, I strongly suggest you spend many hours watching YouTube and Googling about. If you are in the same situation as many there is nobody local who can help.
