Been recommended for a friend due to problems with insomnia ,PSTD ,(post traumatic stress disorder) and anxiety disorder. David helped me to overcome many of my health issues both with psychological assistance and neurofeeback sessions that strongly reduced my anxiety ,stress and reduced as well my insomnia which is still under treatment due to respiratory problems, But much better now .I have extended my sleeping hours from 3,4 per day to 6 and some days a little bit more . I’ll be always thankful for David’s help and highly recommend his assistance and professionalism to anyone with mental health disorders.
