I'm so glad @WhatsitWiggle that this thread has proved useful to you.
I've been meaning to share this (see below) for a while and your post has prompted me to finally do it.
A bit of background: my son (now 15) became very anxious aged 7, rising 8. With hindsight, lots of things had triggered a sudden rise in anxiety, but it had its roots in developmental issues, which long term therapy has massively helped with. Tbh I'm not sure it's that frequent that a child suffers with anxiety without any other underlying issues, diagnoses, traumas etc. Maybe it happens, but I would be extremely nervous of using any mental health provider who doesn't have a sound training in child development and mental health more generally - as how else can someone see what they aren't qualified to help with. I will be eternally grateful that we found someone with this, as I can really imagine what sort of pickle we might be in now otherwise.
Anyway, when I came across Young Vibes (now also marketing as Satsie Thomas and a whole host of other things) and was really worried by their sales tactics and what I later learned of their reputation, I asked the therapist we worked with whether she could offer any signposts to reputable therapists, organisations etc who could offer genuine professional expertise to people in need, who were looking into private help. She gave me a long list, which I share below, in the hope that it may help others.
I know it's a lot to look through and it is such a maze for worried parents. I'm now starting to explore a career in this field (v. very early days, just studying for a Masters as a start so far) and I can say I can see that there is a plethora of approaches which can help families, but its really important to match the help to the family, and above all, for the help to be professional, experienced, well-qualified, very well informed, compassionate, appropriately regulated and in it for the right reasons (to help families, not make money). I completely agree with the post above about how good therapists don't need to advertise or market themselves. Their work speaks for itself, and they are not in it to make money out of desperate families.
Anyway, here is the list. Some of them are more local organisations/therapists (from the Northern Home Counties) but I've left them there as sometimes people work remotely and also I have found that individual therapists/practices can have useful information on their websites. Also, some of the resources seem to lean towards helping fostered/adopted children. If this isn't you, this doesn't mean it couldn't be relevant - certainly my experience was that attachment-based/relational therapy approaches which are more common in adoption (which isn't our situation) were extremely helpful to us. I hope the list is of help to some. Sorry for the very long post!
