Robert Sidney Sinker, 82, a pharmacist who at different times owned three drugstores in the Washington area, including Glen
Echo Pharmacy in Bethesda, died of metastatic cancer March 19 at Sibley Memorial Hospital.
Mr. Sinker, who lived in Rockville, operated his pharmacy like a small-town shop, greeting customers by name, offering delivery
service and making flu shots available twice a year, said Leonard Sinker, his twin brother.
He gave tremendous service, Leonard Sinker said. He wasn't concerned about the chain stores because he knew his
customers would keep coming back. He treated them like they were visiting his home.
Robert S. Sinker was born in the District and grew up there and in several towns in Ohio. He graduated from Central High
School and served as a Navy medical corpsman in the Pacific during World War II.
That experience motivated him to pursue a career as a pharmacist. He attended the University of Tennessee and graduated
from the University of Maryland School of Pharmacy.
Mr. Sinker worked for neighborhood drugstores before opening Washington Circle Drugs in 1965. He ran that store until 1984,
Potomac Village Pharmacy from 1979 to 2003 and Glen Echo Pharmacy from 1994 until his death.
He was a Mason, a member of the Maryland Pharmaceutical Association, an usher and volunteer at Washington Hebrew
Congregation, and avid traveler.
Mr. Sinker and his wife visited Italy, Israel, Greece and Hawaii, among other places.
In addition to his brother, survivors include his wife of 55 years, Marie Sinker of Rockville; three children, Laureen Sadowsky of
Cherry Hill, N.J., Ronald Sinker of Rockville and Abby Eshaghpour of New York; a sister; and five grandchildren.
