He left New Jersey with his family and spent three years with the Chattanooga Heart Institute in Tennessee. He subsequently returned to New Jersey to join Consultants In Cardiology in West Orange, NJ. He established the New Jersey Center For Fainting out of his passion for caring for patients with this frustrating disorder, and he has a large number of patients with dysautonomia who are referred to his practice.

    Dr. Tullo is a fellow of the American College of Cardiology and board-certified in Clinical Cardiac Electrophysiology, Cardiovascular Disease, and Internal Medicine. He has participated in many clinical trials, and enjoys teaching and writing. Dr. Tullo has created a new informational website, www.njfaint.com, for patients and physicians. He has been an active member of the Heart Rhythm Society since 1989. Dr. Tullo is currently Assistant Clinical Professor of Medicine at the Rutgers University – School of Medicine and Dentistry of New Jersey.

    In February, 2014 he performed the first implant in New Jersey of the Medtronic LINQ miniaturized cardiac monitor, and in May of 2014 he was selected by the faculty, resident physicians, and medical students at St. Barnabas Medical Center to receive the prestigious HARVEY E. NUSSBAUM GOLDEN APPLE AWARD for Excellence in Teaching.

    Dr. Blitshteyn is the Director and Founder of Dysautonomia Clinic and a Clinical Assistant Professor of Neurology at the University at Buffalo School of Medicine and Biomedical Sciences.  She completed her neurology training at the Mayo Clinic and received her Medical Doctor degree and Bachelor of Science in Biochemistry, Summa Cum Laude, from the University at Buffalo School of Medicine and Biomedical Sciences. 

    Dr. Blitshteyn's practice provides neurologic care to adolescents and adults with autonomic and other neurologic disorders.  Her research concentrates on pathophysiology and precipitating factors of POTS and includes studies and publications on POTS and autoimmunity, pregnancy, vaccination, headache and vitamin deficiency.  She presented her research at various national and international meetings and received numerous honors and awards for her work on the autonomic disorders.
    Satish R Raj MD, MSCI, FPCPC
    Associate Professor of Cardiac Sciences
    Libin Cardiovascular Institute of Alberta
    University of Calgary, Vanderbilt University

    Satish R Raj grew up in Toronto, Ontario, Canada. He graduated from Queen’s University Faculty of Medicine in Ontario in 1993. After completing residency training in Internal Medicine and Cardiology at Queen’s University he moved on to a fellowship in Clinical Cardiac Electrophysiology at the University of Calgary.

    In 2002, Dr. Raj moved to Nashville, Tennessee as a Research Fellow in Clinical Pharmacology at Vanderbilt University’s Autonomic Dysfunction Center and completed a Masters of Science in Clinical Investigation. He spent 12 years at Vanderbilt University (Nashville, TN) working primarily as a clinical research in the Vanderbilt Autonomic Dysfunction Center. Under the mentorship of Dr. David Robertson at Vanderbilt University, Dr. Raj developed a research program and obtained research funding for studies on postural tachycardia syndrome (POTS) and vasovagal syncope.

    In 2014, Dr. Raj moved back to the University of Calgary to found the Calgary Autonomic Investigation and Management Center at the Libin Cardiovascular Institute of Alberta and the University of Calgary’s Cumming School of Medicine. The clinic is focused on providing high-level autonomic care to Canadian patients with POTS, syncope and orthostatic hypotension disorders. He has also established a clinical research program with protocols for patients with POTS, patients with syncope and patients with orthostatic hypotension.

    He is currently an Associate Professor of Cardiac Sciences in the Libin Cardiovascular Institute of Alberta at the University of Calgary. His clinical focus is on heart rhythm problems (particularly those that require pacemaker and defibrillators) and autonomic disorders.

    Dr. Raj serves on the Board of Directors of the American Autonomic Society (AAS) and the Association for Clinical and Translational Sciences (ACTS).

    Julian M. Stewart, MD, PhD
    New York Medical College

    Dr. Stewart received MD and PhD degrees from the University of Chicago studying cardiac physiology. He is a trained pediatric cardiologist and an integrative physiologist. Dr. Stewart's initial work concerned vascular physiology and was performed in the laboratory of Dr. Thomas Hintze in Physiology at New York Medical College. Subsequently, physiology methods were translated into measurements in conscious humans, largely adolescents and young adults. These are primarily noninvasive adaptations of classical blood flow techniques.

    Dr. Stewart's work and funding now centers around understanding the physiology of orthostatic intolerance in young people, its relation to vascular control mechanisms and their impact on the autonomic nervous system. The technological focus has been on the development and use of methods to measure regional blood flow and endothelial function in patients and in healthy volunteers. He has developed methods using a combination of segmental impedance plethysmography, strain gauge plethysmography, ultrasound and laser Doppler flowmetry along with microdialysis techniques in which he can test the responses to drugs and can measure changes in microscopic amounts of biochemicals. These are applied to the treatment of OI.
