No, it will not be a medical doctor during the expedition.
We like to manage the logistics of our expeditions in the same way that we like to climb for ourselves, so as minimalist as possible to manage a balance with comfort and security. So, while there are no dedicated medical doctors in the group, the lead guide is trained to monitor altitude sickness and adapt the itinerary as needed. The guides are experienced in managing the group's physical condition at high altitudes.
