I have seen 3 lcsw's and one phd. The phd was batshit crazy but not because of boundaries - I only saw that one for a couple of months but I wrote her just like I have the others.
The first lcsw was very loose (I saw her for approx. 2 years about 30 years ago) - she sometimes let clients move in with her, touched a lot, became friends with clients and so on. The two I see now - one keeps saying she has great boundaries (it was in response to me making sure she would stay back and observe my own boundaries) but she has had clients over to her house to watch tv. I write and email when I want.
The second one has said to call any time and I have her home number.
