To Whom It May Concern:

Mr. Harry Campbell has provided biofeedback training in our clinic on behalf of Biofeedback Resources international on several occasions. On each occasion, the training has been invaluable to myself as well as other members of our staff. Mr. Campbell’s trainings have assisted us in increasing our familiarity with the biofeedback equipment as well as increasing our comfort level with the provision of biofeedback services. I have also personally attended one of Mr. Campbell’s forty-eight hour seminars on biofeedback and can attest to the benefits of having taken this course.

I can recommend Mr. Campbell and the company which he represents without reservation. Please do not hesitate to contact me with further questions at (860) 694-4966.

Respectfully,

Steve DiFilinno. LCSW
