The following organisations offer consultancy and training for professionals and both involve the expertise of Phil Christie and Ruth Fidler.
Alternatively you may like some one to one support either via the telephone or email. The PDA Society offer this service through their enquiry line.
The following services offer parent workshops, training and conferences. Many of these are also open to professionals and some events may be specifically for professionals but you would need to contact them directly to find out any details of forthcoming events.
There is also a facebook support group for professionals, although I do understand that many professionals are unable to access facebook due to issues with confidentiality.
