"Lorraine Salter has been giving therapy services to my daughter, Samantha, for 8 years now, and in that time Samantha has progressed significantly in her speech and being able to communicate and understand requests at a higher level then before she started therapy with Lorraine. Samantha enjoys her sessions with Lorraine and has come a long way in her communication abilities thanks to an understanding and very patient person."
