Yes, I do.
Not because he has said it, and he doesn't say it very often. But he has shown it consistently with his actions, for five years. If he didn't care he could just talk for 50 minutes and take my money. He wouldn't write letters or call the GP for me, speak on the phone even evenings or weekends or even when he's been on holiday if something urgent happened with me, text and email whenever I need to, put up with me getting upset with him, and so many other things ... he has proved it to me and I believe it.
He also pointed out that caring about clients is how he gets job satisfaction and one of the ways he finds meaning in his life. He had the opportunity to be e promoted to a management position that would mean not working directly with clients and he didn't take it because working directly with people and caring about them is what he has chosen to do.
