Donor ID: 3709
  • California Cryobank #3709 Came across this info while looking through my paperwork. (We considered this donor along with 2 others, but went with a Danish donor). However, I somehow still had the staff impressions on this donor and thought I would post them, in case any one else was seeking info on #3709. Here are the staff impressions: Personality : Friendly, easy to get along with, a good conversationalist. Overall general impression : Friendly. Although he seemed a bit reserved at first meeting, he is now very outgoing and sociable. He likes sports and enjoys hanging out with his friends.He dresses really simply - clean cut and casual. He has a boyish face. I think he will be a great donor.
