Has anyone here used the services of Dr Dean Handley? Are his chat rooms as viable as he suggests?

There is already a thread for the same topic here:

Dr. Dean Handley So I get an unsolicited email from the good Doctor, see attached image, and I found the content to be interesting.... Anyone else get this same email?

Regards,
ABCTG

I saw those posts but have not come across anyone that has actually participated in one of his rooms or used his consulting services. Still looking. Thanks for your reply!
