About Us

Our Mission

To serve our patients, physicians, colleagues and students by providing the highest quality of neurological care, consultative services and educational opportunities.

Our History

Our Beginnings...

Founded by Dr. Gary Tunell, Texas Neurology had its start as Dallas Neurological Clinic in the mid-1980s. With the addition of Dr. Steven Herzog, Dr. Alan Martin, and Dr. Bruce Jenevein, we had the nucleus of a medical team, and the clinic changed its name to Texas Neurology. Our doctors saw the need for additional services for our patients and began the Texas Neurology Infusion Clinic.

Our Growth...

We soon outgrew our space and moved to our current Gaston Avenue location. We added more physicians, Dr. Daragh Heitzman, Dr. Waleed El-Feky and Dr. Fish Greenfield, continuing our long tradition of recruiting outstanding neurologists. The Diagnostic Imaging Center at Texas Neurology opened, and Electro Diagnostic (EEG) services were available for our patients.

By 2005, the Texas Neurology Sleep Disorders Center opened in Highland Park. We soon added a 3.0T magnet to increase our imaging capability and began serious activity with clinical research studies. The addition of nurse practitioners and physician assistants increased the level of care available to our patients, and with the physicians’ commitment to electronic health records in 2010, our ability to provide quality service improved even more.

Our Future...

Texas Neurology continues to look toward the future with the addition of neurologists, Dr. Gincy Samuel and Dr. Maria Philip. More growth is planned, with additional providers and service locations. Our goal, as always, is to provide the most comprehensive neurological care to our patients, and we look forward to continuing that process.
