Dr. Greg Hipskind
S. Gregory Hipskind MD PhD is a nationally recognized Nuclear and Behavioral Neurologist who specializes in the nuclear brain SPECT evaluation of traumatic and toxic brain injuries as well as their treatment with photobiomodulation light therapy, or PBMT. He received his BS degree from the University of Notre Dame and his MD and PhD degrees from St. Louis University, with his award-winning doctoral thesis research in the area of Neurophysiology. He received residency training in both Neurology and Family Medicine at the University of California, San Diego and University of Colorado Health Science Center, respectively. He became board-certified in Family Medicine and delivered over 600 babies in his private practice. He received 2 US patents for his published research on the neurophysiologic mechanisms and treatment for hiccups. He became a research associate at Western Washington University while in full-time clinical practice and published many peer-reviewed scientific articles in the area of neurobehavioral medicine including the evaluation and treatment of ADHD, traumatic brain injury (TBI) and carbon monoxide poisoning. His recent publication on the use of transcranial LED light therapy to improve cognition and brain SPECT findings in Veterans with chronic TBI has been designated as a high social impact article by several international research organizations. He became qualified in Nuclear Neurology in 2002 and has subsequently personally interpreted over 5,000 nuclear brain SPECT images. He became a Certified Brain Injury Specialist in 2010 and a Certified Polychromatic Light Technologies Instructor in 2018.
Dr. Hipskind has been an invited speaker to numerous professional gatherings at the national, state and local level as well as several international professional societies, including as featured speaker in 2015 on Capitol Hill on National TBI Day regarding the positive effect of photobiomodulation therapy (PBMT) on the brain SPECT scans and symptoms of Veterans with chronic TBI. He has often been invited to speak at the Grand Rounds of the University of Colorado Health Science Center regarding the role of Technology and Medicine in Society. He was a featured speaker at the annual meeting of the World Association of Light and Laser Therapists (WALT) in October 2021 and presented his landmark research on the use of PBMT to reverse the effects of chronic TBI in Veterans. He has appeared on national TV programs including Dr.Phil and “The Truth About Drugs” documentary with Leeza Gibbons using brain SPECT imaging to demonstrate damage that drugs cause to the brain. That show is now a teaching tool used in many high school health classes across America. Dr. Hipskind has successfully advocated for the brain-injured patient in over 150 civil proceedings by successfully defending the validity of the science underlying nuclear brain SPECT imaging. He received the “Distinguished Alumni Award” from his Althoff Prep High in 2023. He has served as President of the Whatcom County(WA) Medical Society, as a member of the Board of Trustees of the Washington State Medical Association, Chief Medical Officer to Brain Matters, Inc and CereScan Corp., brain SPECT facilities, consulting MD toCereHealth, brain software company and Chairman of the Medical Advisory Board and Director of Research for InLight Medical Company. He currently serves as Founder and President of Brain Injury Consulting, LLC and is a member of the Southern Illinois Medical Association and WALT.
