Tony L. Strickland, MS, PhD
Chairman & CEO

Dr. Strickland is a board-certified clinical neuropsychologist with considerable experience in the assessment, diagnosis, and treatment of concussion and related disorders.

He is an Associate Clinical Professor of Neurology at the David Geffen School of Medicine at UCLA. He earned his M.S. and Ph.D. in Clinical Psychology (Behavioral Medicine) at the University of Georgia. He completed a postdoctoral fellowship and research practicum in psychopharmacology at Harbor-UCLA Medical Center; and a postdoctoral fellowship in clinical neuropsychology at the Semel Neuropsychiatric Institute, David Geffen School of Medicine at UCLA.

He is a fellow of the National Academy of Neuropsychology, the American Psychological Association Division 50 (Addictions), and the American College of Professional Neuropsychology.

Dr. Strickland is a Diplomate of the American Board of Professional Neuropsychology. He is a member of the pop Warner Medical Advisory Board, and he consults on Concussion Management Programs for hundreds of club, high school, collegiate, and professional organizations. Dr. Strickland’s research seeks to better characterize traumatic brain injury, dementia, and related neurobehavioral disorders across the life span.

Dr. Strickland utilizes multi-project investigations that employ brain imaging, neuropsychological, and other neurobehavioral assessments to pursue two overarching research themes:

• the understanding of potential differential expression of neurobehavioral disorders among underserved populations across the life span.

• the identification of effective assessment and diagnosis, and potentially promising treatment interventions to be explored in future clinical service and research.

An underlying focus of his work is the development of a research program consisting of experienced and committed professionals conducting innovative clinical neuroscience investigations that attract scientists from regional, national, and international communities.

He has been the principal investigator of a number of National Institute of Health supported research investigations, and has managed a large number of other projects primarily related to clinical neuroscience. He is the author of numerous research articles and has presented nationally and internationally.



Aaron McMurtray, MD, PhD
Sports and General Neurologist

Dr. McMurtray is a board-certified neurologist with a sub-specialty in Behavioral Neurology.

Dr. McMurtray earned his medical degree in 2000 at Vanderbilt University.  His neurology residency training at Harbor-UCLA Medical Center was followed by a Behavioral Neurology fellowship at UCLA/West LA VA Medical Center.

After completing fellowship training, Dr. McMurtray joined the faculty at the University of Hawaii as an assistant professor where he taught medical students, worked on several federally funded population based epidemiologic studies, conducted brain imaging research funded by the American Academy of Neurology, was awarded an American Academy of Neurology Clinical Research Training Fellowship, and completed a Ph.D. degree in Biomedical Sciences.  In 2009, Dr. McMurtray was recruited to join the Ventura County Medical Center where he set up and directed the multispecialty Traumatic Brain Injury clinic and also served on the board of the Ventura County Brain Injury Center.

In 2012, Dr. McMurtray rejoined Harbor-UCLA Medical Center as director of the Behavioral Neurology clinic and the Neuro-HIV clinic, where he instructs Neurology residents and conducts clinical research studies.  In 2013, Dr. McMurtray along with several of his colleagues founded Neurosearch-Torrance, which is part of a multi-site clinical trials company based in Los Angeles and Ventura Counties.  Neurosearch-Torrance plays a crucial role in providing access to clinical research for people living in the South Bay area of Los Angeles who otherwise would not have the opportunity to participate in clinical trials and research studies.

Dr. McMurtray’s primary areas of expertise include: traumatic brain injury, neuro-infectious diseases, and behavioral neurology. He is a member of the American Neurological Association, and the American Academy of Neurology’s Behavioral Neurology and Neuro-infectious Diseases Sections, an investigator at the Los Angeles BioMedical Research Institute, and an assistant clinical professor in the David Geffen School of Medicine’s Neurology Department.  He directs an active clinical research program at the Los Angeles BioMedical Research Institute and his publications include recent studies on memory problems and headache as complications of traumatic brain injury.

Katherine Kruser, Psy.D
Clinical Neuropsychology Postdoctoral Fellow 

Dr. Katherine (“Kat”) Kruser earned her doctorate in clinical psychology at Alliant International University, Sacramento and her bachelor’s degree in neurobiology, physiology and behavior at University of California, Davis. She completed her internship in neuropsychology at San Mateo Medical Center in California. Her clinical training has focused on treatment and assessment of mild traumatic brain injuries, chronic pain, and anxiety. She has received specialized training from field experts in cognitive behavioral therapy, and has evaluated and treated injured workers seeking compensation since 2012. She recognizes the devastating effects cognitive deficits can have on daily life, and holds keen interest in the effects of emotional stress and pain on cognition. She hopes increased public awareness combined with evolving medical advancements in evaluation of sports concussions will bring relief and improved treatments to players and their families.

Dr. Kruser is also passionate about political advocacy and has lobbied both at the US Capitol as well as Sacramento on behalf of California psychologists and our patients on topics ranging from neuropsychologists’ scope of practice within the Workers’ Compensation system, mandated reporting law, patient access to mental health care, and training and education requirements for licensure of psychologists. She is currently serving as the Chair of the California Psychological Association of Graduate Students where she manages student programming and mentorship across the state. Dr. Kruser brings her skills of collaboration, leadership, and clinical experience to best meet the needs of SCI’s patients.

Lina Lee, CBIS

Lina Lee is a certified brain injury specialist (CBIS) and psychometrist with an extensive background in working with a wide array of neurodivergent populations. She earned her B.S. degree in Cognitive Neuroscience at the University of California, San Diego and dove into clinical and interventional research working with incarcerated veterans with traumatic brain injury, movement disorders, and post-traumatic stress disorder. She also conducted research on individuals with mild cognitive impairment and neurodegenerative diseases at the Mary S. Easton Center for Alzheimer’s Disease Research at the UCLA David Geffen School of Medicine. She then moved to Maine to independently run and manage the Acquired Brain Injury Extended Program as a Neurorehabilitation Extender at the RiverRidge Center for Stroke and Brain Injury Neurorehabilitation, where she was trained to carry out physical, occupational, and speech therapy interventions with patients with acquired brain injuries. Through this experience she was able to witness the immeasurable effects of brain injury on daily life but also the life changing progressions made by the collaborative effort brought together by integrative team treatment.  

With her passion coupled with compassion for rehabilitating brain injured patients, she hopes to optimize her role in serving the Sports Concussion Institute, Nexus Clinical Solutions, and Neuropsychological Consultants Inc. populations. Outside of the clinical setting, Lina holds a strong passion for living a healthy, active lifestyle by daily practice of kickboxing and weekend nature exploration!
