Neurorehabilitation Committee Members

Stephanos Kassabalis, Chair
Stephanos joined the Neurorehabilitation Committee in 2019. He has completed postgraduate neurology training with the Carrick Institute for Graduate Studies to become a Diplomate of the American Chiropractic Neurology Board, which makes him a qualified practitioner in Neurological conditions. Majoring in anatomy and neurology, Dr Stephanos Kassabalis completed a Bachelor of Science degree at the University of Adelaide followed by a Masters of Chiropractic degree at Macquarie University.  
In recent years, Stephanos has become involved in community health programs and sporting team’s injury management.

Dr Kassabalis’ extensive training in neurological rehabilitation therapy aims to provide restorative and preventative brain based therapies and treatment programs for people who have been affected by Brain/Central Nervous System Injury and Dysfunction.


Tony Cassis, Vice Chair
Tony as a founding committee member of the Neurorehabilitation Clinical Practice Group, he returned in 2020 after a 2-year hiatus from the committee. Tony has been involved in clinical neurorehabilitation since 2012 when he started a 2-year residency program under the tutelage of Dr. Paul Noone, during which he consulted with hundreds of complex clinical cases. In 2015 Tony became certified as a Diplomate of the American Chiropractic Neurology Board (DACNB) and began his own neuro-rehabilitation practice. His special interest within neurorehabilitation is vertigo, balance and specifically falls-risk.

Tony has assisted on a number of small-scale clinical neuro-rehabilitation trials and is passionate about increasing the level of research and clinical evidence in the rapidly evolving field of neurorehabilitation. He believes that chiropractors, with their unique skillset and training are well placed to be future pioneers and leaders in neurorehabilitation.


Natessa Henville, Research Officer
Natessa’s journey in neuro-rehabilitation began with the 11 week premature birth of her son who had severe retinopathy of prematurity and went on to have developmental delays. Childhood neuro-development and learning disorders continue to be her focus in practice. She believes chiropractors are well positioned to recognise and alter the developmental trajectory of these children and her goal is to see her colleagues equipped to do that. A past member of CAA (QLD) and ASRF Boards, she joined the AICE Neuro-rehabilitation Committee in 2022.

Natessa competed a Bacehlor of Science at University of Queensland and as Masters Of Chiropractic at Macquarie. She was certified as a Diplomate of the American Chiropractic Neurology Board (DACNB) in 2013 and as a Diplomate of the Australian College of Chiropractic Paediatrics (DACCP) in 2021. (Her son commences a Bachelor of Music in Composition at Griffith Conservatorium in 2023).

Danielle Gregory, Education Officer
Danielle has trained in applied clinical neuroscience since 2009. She has included periods of general chiropractic practice, and also those where the majority of the caseload was with complex cases. She has held various roles within professional bodies related to the chiro-neuro special interest, including education, developing and running professional conferences, mentorship, and board membership. Danielle also teaches her own original content seminars on the vestibular sense.

Danielle hopes that her participation within the AICE committee will further the important task of developing and embedding the scope of practice that is unique to applied clinical neuroscience, and to continue to bring neuroscience to the practical utilisation of every chiropractor. Further interests include expanding the awareness and practical utilisation of the basic science of central and computational vestibular neurophysiology to regular vestibular rehabilitation practice, and to areas of practice with vestibular involvement is apparent but mysterious or unable to be easily accessed and applied by providers.

Eric Hansen, Communications Officer
Eric became certified as a Diplomate of the American Chiropractic Neurology Board (DACNB) in 2012 and began to further his study in Vestibular Rehabilitation and helping people to recover from Post-Concussion Syndrome. He now runs a multi-disciplinary clinic in Gladesville focusing on childhood neuro-development and adults with Concussions, vestibular issues and dysautonomia.

Eric's goal is to help bring greater awareness to chiropractors on the research behind neuro-rehabilitation and arm them with the tools they need to serve the community.
