John Tzanos, Ph.D., is a licensed psychologist in CA, CO, FL, and MN who provides telehealth Cognitive Behavioral Therapy for Insomnia (CBT-I) for adults with chronic insomnia and other sleep-related difficulties. His work is practical, structured, and research-supported—using core CBT-I components such as sleep scheduling (sleep restriction/compression), stimulus control, cognitive therapy for sleep-related worry/rumination, and circadian-informed behavioral strategies (e.g., timing of light, activity, and sleep routines), with an emphasis on measurable progress and relapse prevention.

Dr. Tzanos specializes in helping clients identify and change the patterns that keep insomnia going—such as conditioned arousal at bedtime, nighttime anxiety, unhelpful compensatory behaviors, and “sleep effort.” He frequently works with people whose sleep issues occur alongside anxiety, OCD, trauma-related symptoms, ADHD, and chronic pain, and can help coordinate next steps when medical sleep concerns (e.g., possible sleep apnea) are part of the picture.

In addition to CBT-I, Dr. Tzanos is trained in ACT, ERP, CBT, and clinical hypnosis, which he may integrate when helpful to reduce struggle with wakefulness and build a calmer, more consistent relationship with sleep. His CBT-I training includes the Beck Institute CBT-I live workshop, MUSC’s web-based CBT-I provider training, and a PESI CBT-I intensive (19 hours).
