 Hi, my name is Tina Chang. I'm an optometrist with the UCSD Predental Society. I was asked to join on by a friend of mine who knew about the mission because they were short on people who could help others see. So when I came aboard, my most memorable moment was that when we had a patient come in who was unable to be helped by surgery and she was unable to see, we were able to fit her with some glasses and for the first time in years she said she was able to see. She was happy that she could finally be able to leave her house, walk around, perhaps cook, and she was just ecstatic. She hugged us as she was leaving and that was my most memorable moment. I think that this mission is great. We're not able to help everybody but just being able to help a few is in my mind a success for this mission. So I definitely recommend this mission for everybody who has skills and has been blessed with a lot and is willing to give up a little bit of their time to sacrifice a little bit to give back to those who are in need.
