John Tzanos

John Tzanos, Ph.D., is a licensed psychologist who provides personalized, online Cognitive Behavioral Therapy for Insomnia (CBT-I) for adults struggling to fall asleep, stay asleep, or return to sleep after waking too early.

When sleep becomes a nightly struggle, bedtime can bring frustration, racing thoughts, and worry about getting through the next day. Dr. Tzanos helps clients understand what keeps insomnia going and develop practical skills to improve sleep, reduce sleep-related anxiety, and function better during the day. His approach is collaborative, structured, and responsive to each person’s health, circumstances, and goals.

Treatment begins with understanding your sleep patterns and the factors affecting them. Using sleep diaries and regular feedback, you and Dr. Tzanos develop and refine a personalized plan. CBT-I may involve carefully adjusting your sleep schedule and time in bed, strengthening the connection between bed and sleep, and changing thoughts and habits that perpetuate insomnia. Sessions include clear explanations, practical steps to use between appointments, and a plan for managing future setbacks.

Dr. Tzanos also works with adults whose insomnia occurs alongside anxiety, OCD, ADHD, depression, trauma-related symptoms, chronic stress, or chronic pain. When helpful, he incorporates Acceptance and Commitment Therapy (ACT) strategies to address the pressure to “force” sleep and help clients respond more flexibly to worry and wakefulness. When symptoms suggest sleep apnea or another condition requiring medical assessment, he helps clients connect with appropriate medical or sleep-medicine care.

His CBT-I training includes the Beck Institute’s live CBT-I workshop, the Medical University of South Carolina’s web-based CBT-I provider training, and a PESI CBT-I intensive.

Secure telehealth appointments are available for adults ages 18 and older physically located in Arizona, Colorado, Delaware, Florida, Minnesota, and Washington. Services are available in English and Greek.

To explore whether this approach fits your needs, contact Dr. Tzanos to discuss treatment.
