You can search for any discussions about doctors using the magnifying glass icon, and have a look at the Doctors List in the Doctor Info category; here’s a link to that in case you’ve not seen it:
Doctor Lists – no discussion - Symptoms and Treatments / Doctor Information - Living with Eagle
Dr Pressun isn’t on our list; not to say that nobody’s had surgery with him, but not everyone posts regularly on here.
Good luck with your search!
