Mr. Harold was a great volunteer. He helped us for a month. I am very glad to work with him. In the time of his stay, we had 6-7 international volunteers and some other Vietnamese. He is the oldest volunteer here, but I did not see any distance of ages between Mr. Harold and other volunteer. Mr. Harold is very nice, honorable, and responsible. He also a very funny person. We were happy and comfortable to be around him. I would like to recommend him to anyone who is looking for the volunteer for their organization. Thank you very much for your help, Mr. Harold. Please do not forget to contact me when you have a chance to visit Vietnam one day. Take care!
