Sex & pornography addiction, infidelity, substance abuse & addiction, trauma, couples


If you or someone you love is struggling with pornography, infidelity, or sex addiction, and if you’re lying to someone or are lost in the haze of someone else’s lies, you’re not alone. Clients often describe feelings of shame, hopelessness, and fear of being honest with their partners. Partners feel hurt, betrayed, angry, and anxious. If you feel surrounded by a lifeless landscape of sex or porn addiction and infidelity, I can help. I provide a confidential, non-judgmental space in which you can learn to make different choices, discover healing, and create the life you want.


As a Certified Sex Addiction Therapist (CSAT), I specialize in working with individuals who suffer from addictive and compulsive sexual behaviors. While this training helps me bring about immediate change to problematic behaviors, I believe that lasting change involves the transformation of emotional life. That’s why I also have training in EMDR and from the Institute for Contemporary Psychoanalysis in order to help you create lasting change. My theological training and faith background helps me support Christian men and women as they surrender to God and heal.


I work primarily with individuals and couples with sex addiction, infidelity, and relationship issues. I help my clients feel more fully alive and genuinely connected in their relationships. If you’re ready to work toward more aliveness in your life, I invite you to contact me. Together, hope is possible.
