According to The Story of Dunwoody, written by Ethel Spruill and Elizabeth Davis in 1975, there have been seven different post office locations in Dunwoody.  Much of the post office history they gathered came from Sentell Spruill, retired Dunwoody postmaster. 

Mims recalls, “Brookhaven Supply at intersection of North Druid Hills and Peachtree Road, Buice Sinclair was next, Bagley Electric, laundry, Brookhaven Pharmacy, gasoline station with fire station behind it, and the A&P just to start. The Brookhaven Picture Show was across from the Drug store and was run by Mr and Mrs Tittle.” He remembers there were many more stores along Peachtree Road.

The building was a store and post office. It was first the location of the Nash Store and later became Thompson’s Grocery. The door on the left led into the post office. The middle and right door led to the grocery store. Mrs. Thompson, known by the locals as Miss Lottie, would ring up the sales on the cash register.

The story of how Dunwoody got its name has been passed down from early families and it goes like this: Major Charles Archibald Alexander Dunwody applied for a post office for the area and an extra “o” was added to the name.

Benjamin Franklin Burdett built a Colonial style, two story, red brick home in 1900 on the land where Mount Vernon Presbyterian School and Church are located today. The home had eleven rooms, four porches on the ground level, two porches on the second level, and white columns across the front. The bricks for the home were made on the property.

Around 1924, when the Roswell Railroad was no longer operational, the Dunwoody Depot was rolled up Chamblee-Dunwoody Road on logs to a new location. The Depot was originally located between where CVS and Chevron are today on Chamblee Dunwoody Road. The new location was the southwest corner of the intersection of Chamblee Dunwoody Road and Mount Vernon Road, where BP is today.
