Dr. Levi Armstrong is the owner of Neurobehavioral Consultants, PLLC in Paris, Texas and co-owner of Integra Psychological Services, PLLC in Wylie, Texas and a clinical neuropsychologist (Texas #36271) specializing in the evaluation of a wide range of medical, neurological, and psychiatric problems for children, adolescents, and adults. Born and raised in rural northeast Texas, he is passionate about increasing access to mental health services to under-served populations and is an active advocate for legislative provisions in line with this goal. He provides psychological and neuropsychological services for children, adolescents, adults, and older adults and is contracted with various agencies such as the Social Security Administration (disability evaluations), the Department of Rehabilitation Services (DARS) / Texas Workforce Commission (TWC) for vocational rehab services, MHMR for IDD services, and as an independent psychologist examiner/consultant for local school districts for ADHD testing, learning disability evaluations, and FIE's. He has had hospital privileges at Paris Regional Medical Center (PRMC) since 2015 and has consulted in the outpatient neurology, outpatient PM&R, and inpatient geropsychiatry departments. 

Dr. Armstrong earned a bachelor's of science from Texas A&M University - College Station in community health/biomedical science, a master’s degree in psychology (professional counseling emphasis), and a doctorate in clinical psychology with a specialty emphasis in clinical neuropsychology from the University of the Rockies in Colorado Springs, Colorado.

Additionally, earned his post-doctoral masters of science degree in clinical psychopharmacology from Fairleigh Dickinson University, which affords him advanced knowledge and clinical training in the clinical application of psychotropic medications. At this time, however, Texas does not allow psychologists with this advanced training to prescribe. Although he is available to consult with his patient's prescribers, Dr. Armstrong cannot and does not prescribe medication. 

Dr. Armstrong is a member of many professional organizations including the Texas Psychological Association (including the psychopharmacology legislative committee), National Academy of Neuropsychology (NAN), the Academy of Medical Psychology (AMP), and the Early-Career Neuropsychologist Division of the American Psychological Association. In addition to his private practice, Dr. Armstrong is also a full-time graduate  professor in the Human Behavior and Counseling Department at Amberton University in Dallas, Texas where he teaches graduate counseling coursework to prospective master's level professional counselors. He is very passionate about the the evaluation and treatment of brain disorders as it is related to psychology, neurology, psychiatry, and general medicine via psychopharmacology, counseling, and neuropsychology.

Dr. Armstrong is happily married to his best friend and beautiful wife. They have a precious daughter and son who keep them laughing (and very busy!). In his free time, he enjoys spending quality time with his wife, playing with his kids, playing guitar, and going on walks with his children: Rio the Labrador and Lucy the Mini Border-Doodle. In the fall, you're most likely to catch him watching his alumni the Texas A&M Aggies play college football on Saturdays. He attends church in Wylie, Texas and is a proud sponsor of Wylie Young Life & Lamar County Young Life. As such, he believes that every human being, including his patients, deserve to be treated with dignity and compassionate acceptance, grace, and love.
