Kathleen Cantrell, Ph.D.

Dr. Kathleen Cantrell opened her own private practice in June 2018 (Enduring Hope Psychological Services) where she works with children (age 8+), adolescents, and adults. She left her full-time position as a Licensed Psychologist at Cook Children's Medical Center in February 2019.  Her primary role at Cook was psychological testing and therapy with children and adolescents.

Dr. Cantrell earned her Bachelor's Degrees in Psychology and Sociology from Stetson University in Florida.  She immediately pursued her Master's Degree in Counseling Psychology from the University of Kentucky.  After taking six years to work as a Career Counselor/Trainer, she returned to school at the University of Denver to complete her doctorate in Counseling Psychology.  At that time, her focus was Industrial/Organizational Psychology.  When her first son was born with significant disabilities, life took a dramatic shift.  Following her Pre-Doctoral Internship at the Texas Woman's University Counseling Center, she took time off to work with her son.  With the focus of wanting to help others, she became involved with The Arc of Greater Tarrant County as a parent leader of the Our Special Children parent group.  She was then voted onto the Board of Directors, and in 2004, became the Executive Director of the Arc.  She remained in that position until she left to complete her dissertation which was completely revamped to focus on Mothers of Children with Intellectual Disabilities.  Following her graduation in 2007, she became a Post-Doctoral Fellow at Cook Children's Medical Center.  This position evolved into a full-time Licensed Psychologist position.  She worked with Cook for over 11 years.
