Dr. Gail Gnade

Senior Clinical Consultant


Dr. Gail Gnade has been a Clinical Psychologist in the state of Tennessee since 1993. She graduated with a Ph.D. in Clinical Psychology and a Master’s Degree in Theology from Fuller Theological Seminary, the largest multi-denominational Seminary in the world. Early in her Career Dr. Gnade was a Certified Chemical Dependency Counselor in the Chicago area and in Pasadena, CA when she was pursuing her PhD.  Dr. Gnade has been with Focus Treatment Centers in various capacities for over 10 years.

 Dr. Gnade’s specialties include:  Addictions, Eating Disorders, Anxiety, Obsessive Compulsive Disorder, Mood Disorders, Relationship Difficulties, Personality Disorders, and Recovery from Childhood and Adult Traumas (utilizing Somatic and Attachment Focused Eye Movement Desensitization Reprocessing, S.A.F.E.).

Dr. Gnade’s passion resides in integrating evidenced based treatment modalities in treatment and the recovery process through the lens of Interpersonal Neurobiology, Poly-vagal Theory (Social Engagement Theory) and Spirituality, with a strong emphasis on the mind-body connection and integration.  In other words, she believes that we have been created to trust and connect with one another as human beings and when this goes awry for various reasons we may cope in a myriad of ways (including substance abuse, eating disorders and other addictions).  Dr. Gnade has found in her own healing process and in witnessing others, that it is indeed true; learning to safely connect with others, oneself and a power greater than oneself is foundational for recovery and living a purposeful and meaningful life.  

During her free time, Dr. Gnade enjoys spending time with family/friends, daughter, two granddaughters, reading and learning, finding humor in everyday life, and spending time with her pet/friend, “Bo,” a Collie who is trained as a HABIT Volunteer (Human Animal Bonding in Tennessee).
