Hard To Find A Surgeon Trained In G-POEM

I’m Paula. I was diagnosed with gastropresis in December of 2016. I’ve had Botox on my vagus nerve but that only helped temporarily. I’m seeing my GI doctor soon and we’re looking at either pyloroplasty or G-POEM as a next step. Hopefully it’s the G-POEM because that’s less invasive but I’m told it can be hard to find a surgeon trained in G-POEM. 
I’m a wife, married 31 years. I have two sons, ages 31 & 24.
