Heidi Marker, based in Kingsport, Tennessee, runs Power Over Darkness Ministries, specializing in Inner Healing and Deliverance. With over 30 years of experience, she has guided over 1,000 clients through transformative counseling sessions. Heidi's approach is rooted in Charles Kraft's "Two Hours To Freedom" method, which involves journeying through clients' lives to address past traumas and generational issues. 

She offers three services: Personal Issue Counseling, Inner Healing Counseling (2-5 sessions), and Deliverance from demonic forces (available after inner healing). Heidi emphasizes that inner healing is 90% of deliverance work, as it clears the "soul garbage" demons feed on. Her ministry aims to help individuals find freedom, heal past wounds, and renew their minds, leading to deeper intimacy with God.
