I do not.
I know that many now offer an online version of hypnotherapy, but I find that I have the greatest success with old-fashioned person-to-person contact.
I'm trained in body language, micro-expressions and more and I find that having my client right there in the room with me provides the best experience and results. Online is not the hypnotherapy experience I would want to receive, so I don't offer it to my clients either.
On top of that, I worry about poor connection quality and getting disconnected as well.
Recently questions about what the rules are in various jurisdictions and whether the jurisdiction I am in or the one the distant client is in is the one that matters have arisen, that make me even more skeptical of online hypnotherapy.
