I went for a consultation when he was in Jeju, and the interior was… like an old local clinic in the neighborhood. I heard the Seoul clinic he moved back to was self-decorated by the director. All the information is on the blog, so I recommend reading it carefully.
He has great pride in his own surgeries. He is cynical, and even when you ask questions, rather than answering in a firm and exact way, he speaks indirectly as if using analogies, so it’s hard to understand what he means. He values trust and faith between doctor and patient, so if you ask questions that sound doubtful, he becomes sharp. He gives off an eccentric feeling, but if his type suits you, he is pleasant and his humane side stands out too. I’ve been reading the director’s blog for years and feel a strong sense of familiarity, so personally I trust him.
