I still hardly know what to say other than that I very much appreciated the very well organized and co-ordinated approach to assessing me. I’ve never had such a thorough or compassionate health assessment and I’m still a bit blown away by how it felt to be communicated with in this careful and respectful way. I feel immensely privileged to have experienced this  and incredibly encouraged and optimistic.
