Becky and Layna,
I was shocked to find out that Don died. I was at the Perio Meeting on Miami and met Rick Young and he told me the sad news. During our residencies at U of FL he was always upbeat, cheerful and laid back. I remember visiting the office soon before he opened it in 1989. I cannot imagine your grief. He was so young at 58. I am in shock. If there is anything I can do please contact me.
