After 49 years in practice, Dr. Jonathan Lyons has retired from office practice. For his patients, our long time partners Dr. Thomas Yau and Dr. Arusha Gupta will be available to provide for a smooth transition. For those patients and colleagues for whom he has provided Electroretinographic consultation we recommend, Dr. Reshma Katira of the Retina Group of Washington with office hours in Silver Spring as well as Alexandria, Virginia. She has been providing excellent electroretinographic consultation and testing with the facilities and experience to continue to serve the community. We thank Dr. Lyons for his hard work and dedication to patients.
