About Us

MDChat was developed by Mobile Health One, a national healthcare communications technology company founded by respected neurosurgeon and successful entrepreneur John Abrahams, M.D.

While building the largest neurosurgery practice in New York’s Westchester County, Dr. Abrahams was often frustrated by his inability to reach existing colleagues or referring professionals but found existing platforms were nothing more than social media tools with no true patient care, regulatory compliance or practice productivity benefits. This frustration led to a promising, innovative solution: MDChat, the first HIPAA-secure communications platform designed to improve workflow productivity within and between healthcare environments.

Ezriel Kornel, M.D. Board Member

A principal of Brain & Spine Surgeons of New York since 1990, Dr. Kornel is in the forefront of minimally invasive neurosurgery (MIS). Dr. Kornel has become an expert in minimally invasive endoscopic surgery of the spine as well as minimally invasive approaches in the surgical treatment of brain tumors. He is one of the first neurosurgeons in the New York metropolitan area to replace damaged cervical discs with the newly introduced artificial discs. He was trained in Stockholm in the use of the Gamma Knife and utilizes this stereotactic radiosurgical technique for the treatment of brain tumors as well as for the treatment of trigeminal neuralgia. He is also the director of the Institute for Neurosciences at Northern Westchester Hospital in Mount Kisco, NY and is affiliated with many of the leading hospitals in the area.

Dr. Kornel gained his initial expertise during his neurosurgical residency at the George Washington University Medical Center under the tutelage of Hugo Rizzoli, M.D., at the time one of the most renown and respected neurosurgeons in the world. Dr. Kornel has numerous mentions in the biography of James Brady, press secretary to President Reagan, because of his involvement in Mr. Brady’s care after his tragic gunshot injury.
