John Marchini started his final year MSW internship with FDNY Counseling Service Unit the day before 9/11. In his 12 years working there he gained expertise in the treatment of PTSD, mood disorders, and addictions. As the only therapist interested in working with sexual issues, in 2005 he trained under Patrick Carnes to become a Certified Sex Addiction Therapist. However, he subsequently saw the sex addiction model as overly restrictive, moralistic, and ultimately not helpful to those in need. John has been in private practice since 2013 working with adults of any gender and sexual orientation who practice non-normative sexual lifestyles.
