Samaritan's Purse transported the emergency field hospital and medical personnel to the country following the 7.8 magnitude quake on April 16.
Simon Barrington from the charity told Premier they are grateful for their volunteers.
He said: "They're just ready to give their lives in this situation and come alongside people in their times of need, and really do what Jesus told us to do, which is just go and do likewise with the parable of the Good Samaritan.
"They're incredible people and we thank God for them and their willingness to serve in these situations."
More than 600 people have been killed and thousands injured.
Simon Barrington went on to say the hospital is working in partnership with other medical services in the country.
"We come alongside and support, so we're actually acting as an overflow for the hospitals that are there, we're taking cases that they can't deal with, we're bringing in technical expertise that can't be dealt with.
"We'll just be there in the short term to manage this peak in requirement."
The hospital has an emergency room with the ability to see more than 100 people a day and an operating theatre with the ability to perform 7-10 surgeries daily.
It also has 20 inpatient beds, and an outpatient clinic with an joining lab, ultrasound imaging capabilities, and onsite pharmacy.
Addressing what people can do to help, Simon Barrington said: "Pray for the survivors, pray for those who've lost loved ones, pray for those teams providing critical medical care and saving lives every day and remember the people of Ecuador at this time."
