Oden Picture .jpg

Kathryn E. Oden, Clinical Neuropsychologist, PhD

I am honored to meet with you and determine how we can work together to help you heal your emotions, improve your relationships, reach your goals, and experience more happiness and fulfillment in life. I provide therapy to adults, adolescents (age 10 up), families, and couples.

I tend to see everyone as an individual with a unique story of the past and goals for the future. I believe that how you tell that story may affect the ways you can imagine creating your future.  I can help you change limiting beliefs.

Because I have family members and close friends who come from a variety of ages, cultures and sexual orientations, I try to provide an environment where you can feel comfortable sharing your issues, even if they are frightening or embarrassing to you. I started college as a Drama major but changed to Psychology as a junior (and graduated on time)! I earned a Master’s Degree from Texas A&M University where I was fortunate enough to be a Lechner Scholar.

 As a Master’s level clinician, I worked in the Psychiatric Hospital for the Texas Department of Corrections and the Intake Unit where I tested new inmates.  As I got interested in why the folks who had difficulty following society’s rules also had difficulty understanding the rules of the prison, I learned that many of them had a history of physical abuse and neglect.  I returned to graduate school at the University of Houston and learned techniques to help find cognitive problems (whatever the cause) using testing and then to help individuals and their, blood or chosen, “families” manage those thinking issues.  I worked with both children (at MD Anderson Pediatric Brain Tumor unit) and adults (some with brain injuries and dementias) during graduate school and afterward.

 I also led a group for grief and loss at a senior center while working as a hospital psychologist and doing testing at the psychiatric unit. I had the opportunity to work with patients facing major surgeries (such as spinal and bariatric). So I do evaluations of persons age 10 and over, to find the reason for problems with thinking (such as attention/concentration, memory, logic, and learning) as well as personality and behavioral problems.  I work with the individual, and with the “family” to help them learn skills that can support the patient.

My areas of counseling include supporting those with cognitive issues, anxiety and other mood disorders, and relationship challenges. I have experience working with people who have PTSD. My mode of therapy is typically interpersonally focused and narrative; I believe this is useful to help you gain insight into environmental triggers and to learn skills to change behaviors that interfere with the life you choose to live. I also use Mindfulness Therapy when working with clients, an approach that helps you better cope with mood/anxiety issues on a daily basis and avoid being overwhelmed.

My history includes moving a lot as a young child and then finishing my adolescence living on a native american reservation.  I have been a licensed psychologist, first at the Master’s level since 1986 and then as a Clinical Neuropsychologist since 1997.  I have experience working with children who have brain injuries and developmental issues, adults with chronic health conditions (including obesity and pain), and older adults facing cognitive declines related to age or mood.  I believe there is no such thing as a disposable human being!
