Hear it in context
Notice where the phrase sounds natural.
I completely agree with your opinion on this matter.
In my opinion, I completely agree that exercise is essential for a healthy lifestyle.
Fix the pattern
One small grammar move makes it sound right.
Not: I'm completely agree with you.
Say: I completely agree with you.
'Agree' is a verb — drop the 'am/'m'.
Which sounds natural?
Tap the one a native speaker would say.
'In complete concurrence' is absurdly formal; 'I completely agree' is the natural reply.
