My daughter Amy has volunteered (actually pays to volunteer – thanks to all those who donated to cover her expenses) to serve on the Mercy Hospital Ship. Until early June it is anchored off the coast of Benin Africa. Amy is serving as a Nurse taking care of patients pre and post-operatively. Patients get life-saving and life-altering surgeries, many for conditions that would be caught and fixed much earlier in more medically-advanced countries.
She got there in early January and returns to America in June. Several of her friends encouraged her to blog about her experiences. You can read her blog here:
