So sorry for the Douglas’s loss.  I just saw this today.  I met Dr Douglas in 1978.  He took on being my orthodontist.  I was so proud back then because he used my very maligned mouth as a case study.  My smile was perfect when he was done.  He was such a nice man, so professional, and an expert orthodontist.  I owe my smile to him. Deepest Condolences
