Puno is a region in Peru that is underserved in many respects: It has the country's highest child mortality rate. The region is more than 4115 metres above sea level — which places great stress on the human body. As a result, children who are born with deformities have a very low chance of survival; this is not only due to the harsh climate, but also because of the lack of healthcare. While some hospitals have an intensive care unit for newborns, they cannot afford to provide follow-up treatment or long-term therapy. Patients who undergo an operation in Peru even have to bring their own saline solution with them when they are admitted to hospital. They often have to travel long distances by bus or on foot to reach the hospital.

Many children in this region suffer from deformities, which often means they become the victims of mobbing by their peers. Most of the children's families can only hope for a "miracle operation". But in most cases, they do not have the financial means. This is where the organisation "Angels of Charity and Music (ACM)" comes in.

In 2018, on the initiative of a former colleague, Javier Montero (previously at Great Lakes Toronto), the Schinzler Foundation, in collaboration with Angels of Charity and Music, funded a total of 16 operations on children with deformities to help those affected, and allow them to lead carefree lives. The operations and the several months of follow-up treatment were organised and performed by an international team of doctors working as volunteers at ACM.
