They are active, I consulted with their head english consultant Tony Medina (who also runs a ps tourism company that assists foreigners - "Seoul Guide Medical" which is similar to docfinder etc). He's a native Canadian and is therefore fluent in english and was really helpful when I was consulting with him, since I couldn't find much information on their clinic at the time I decided not to go with them however, just due to lack of knowledge.
They did a video with a Korean youtube duo BapMokja and Haeppy:
Hope this helps!
