I'm not able to find any specific information about endocrinologists in the Decatur, GA area, but the Transgender Clinic at Darmouth-Hitchcock Medical Center maintains referral information and they may be able to help you find a provider to prescribe and monitor your hormone therapy. Their phone number is(NNN) NNN-NNNN
I have two excellent resources about MTF hormone therapy which may be useful to you.
I hope this guidance is helpful. Very best wishes for the journey you're embarking on. JanelleRPAC
