Sandra Coulson , the "thumb Whisperer", is a Certified Orofacial Myologist and past president of the International Association of Orofacial Myology. This therapy treats tongue thrust, habitual mouth breathing, poor head, body and lip posture, thumb and finger sucking, nail biting, and trichotillomania as these relate to the function of the mouth and tongue. This therapy is also effective in treating other issues such as Down syndrome, stroke, and snoring when done in cooperation with other professionals. The "Thumb Whisperer" title has evolved because 99.7% of all patients referred for thumb finger and nail biting habit cessation, stop on the FIRST DAY! Orthodontists, dentists, pediatricians and other professionals refer for this therapy. It is an effective aid to their treatment.
