Dunwoody city officials and residents are in shock after learning an “amazing citizen” died from injuries sustained in a car crash Monday.

Roberta “Bobbi” Sedam on Aug. 11 was honored with “Bobbi Sedam Day” by the mayor and city council for her work on the sustainability committee. Councilman John Heneghan wrote in his blog Wednesday that “Bobbi Sedam touched the lives of so many people in such a positive way.” Heneghan published his thanks to the woman who “contributed to so many causes.”

Councilman Terry Nall said Sedam has always been the voice of moderation at meetings, has always stood up for what she thought was best for Dunwoody and the environment and she has “long been integral to the fabric we call Dunwoody.”

“What molds a city into a special community is the thread of the fabric that each citizen contributes,” Nall said. “Through her passion for the environment, she made an immeasurable difference in our community. Her fingerprints of sustainability leadership appear all across Dunwoody.”

The funeral service will take place at St. Jude the Apostle Catholic Church in Sandy Springs at 11 a.m. on Friday, with a reception after at the church social hall.

“We will always remember Bobbi saying, with that twinkle in her eye, ‘People think I’m just a little old lady!’ She loved this community and we loved her,” Nall said. “Bobbi will be greatly missed, but her legacy will live on into the future.”
