Dr. Serena used to be our wound specialist and he was wonderful. He moved, or something, and we could no longer get in touch with him.
He has a facebook page: https://www.facebook.com/thomas.serena.9
and he has his own site http://www.serenagroups.com/index.html
but there aren't a lot of options to contact him.
I would ( have you already? you might have. ) talk to Dr. Levitin about wound care and take whatever advice he gives. Honestly, I would trust Dr. Levitin with all medical questions around here ... he's very good.
