Dr. Darwin Martin Koller, MD

Probably, no not probablydefinitely the worst doctor I have ever taken my child to. He doesn't listen. He likes to make assumptions jump to conclusions. ultimately, he is the doctor, he's right you're wrong. Nothing you can do about it. I still experience PTSD from what he put me my husband in our family through.

Dr Koller is the worst doctor ever. He is very rude and condescending to the child and parents. He doesn’t handle being called out confronted. If you have a child please refuse to see him. He only causes more damage and doesn’t fix the child . He is a horrible,horrible human and doctor

He is extremely rude and does not know what he is doing... Then when confronted he said he is the physician... He see kids everyday.... I do not recommend if you are in the Columbus Ga area.

He is a bully to parents & abusive to children. He is rude and condescending. He laughed and told me nothing was wrong with my child & I was ridiculous for bringing my child in to the ER at 3:30 in the morning. He made fun of my child & did NOT do an assessment.
