Columbus support groups
There's one with OhioHealth Weight Management. I'm not sure what day it is--I want to say third Tuesday in the month, but I'm really not sure on that.
I think they'd be cool with anyone coming, not just folks who had surgery there. The bariatric programs nearest to where I live are fine with people who've had surgery at other facilities coming to their support group meetings.
So, come to think of it, there's probably also a group at the OSU program.
Good luck!
