Rockville, Maryland (Neurology)

Meridian's Rockville, MD (Neurology), location performs clinical studies related to disorders of the nervous system. Typical studies at this site explore medicines developed to treat migraines, Alzheimer's disease, multiple sclerosis, seizures, epilepsy, and other conditions.

Meridian partners with The Neurology Center, which is the premier provider of neurological services in the Washington DC metro area. The Neurology Center provides convenient, state of the art services to patients, referring physicians and the community.

This single specialty practice was started by Marvin Korengold, MD and Howard Silby, MD in 1969 in downtown Washington, DC. Additional offices were established in suburban Maryland and elsewhere in the District as the practice grew and added physicians. The group has long maintained a reputation for excellence. Its physicians are well represented in the listing of Top Doctors in "Washingtonian Magazine" and are recognized as well by their inclusion in other local and national peer-selected listings of excellent doctors.
