Seth Thomas from Guildford visited Asso Village in the north of the country in 2017 and was moved to make a difference for the people there.
The Christian community he visited in Kaduna state are regularly targeted because of their faith and were in desperate need of a new health centre.
Using his network he was able to secure funds from donors and his school within just 9 months to pay for the clinic.
Encouraging other teenagers to make a difference, Seth told Premier: "I think impossible is two letters too long.
"What I did was change things in the world of Asso Village. Imagine what would happen if everyone my age did something like this. That could change the whole world."
Thanking him for his fundraising efforts, Rev Yunusa Nmadu, who will oversee the clinic said: "I am so thankful for the vision Seth had to build a hospital/clinic for the local people following his visit to Asso a year ago.
"The villagers are immensely grateful, because in addition to providing building work for them, when completed the facility will ensure that healthcare is easily accessible and will without doubt save lives in the area."
Seth hopes to return to the community soon to open the clinic and to spend more time with the villagers.
