Licensed Clinical Social Worker in New York State, License Number 087305-1

Christine V. Barker is a Licensed Clinical Social Worker in the states of Florida and New York with specialized training in Dialectical Behavior Therapy (DBT).  She has over 20 years in clinical social work and management in New York City and Florida in settings that include outpatient and emergency mental health; day treatment; foster care; juvenile justice; residential treatment; and runaway and homeless youth programs.  Originally from Brooklyn, NY, she has a bachelor’s degree from Barnard College and a master’s degree in social work (MSW) from Hunter College in New York City.

Christine was trained in DBT as a therapist with the New York State Office of Mental Health Intensive Day Treatment program in Brooklyn, NY, completing the 10-Day Core DBT Clinical Training in 2014.  She was part of a team that implemented DBT skills training in the daily community meetings with youth ages 8 to 18 with serious mental health problems.  It was exciting to see how effective DBT concepts and skills were in helping teenagers and children with a range of problems such as anxiety, depression, aggressive behaviors, hyperactivity, emotion dysregulation, and difficult family situations.

Since relocating to Tampa Bay, Christine is grateful to be continuing her DBT practice as a therapist with TBC for CBT.  She is committed to ongoing training and most recently completed the 4-Day Intensive Training in the DBT Prolonged Exposure Protocol for PTSD in October 2018.
