Is the job you are applying for related to your non-profit work or your analytics work? If it is the later, I'd address the nonprofit work in your cover letter, but keep your resume focused on the jobs that relate to the new one for which you are applying.
I like the way it's listed on linkedin, a separate section listed as "volunteer" (you could change the name to professional organizations or something like that) and then you can detail it out there.
I serve on a non-profit board and that's what I do.
I agree with 1confused1. I have two separate sections on my resume - professional experience and volunteer experience. Both are important and help show your future employer who you are. GL!
I'd hesitate to put it under volunteerism, since these are things you founded and are currently at the helm of. Id probably add a section to my resume with the heading "Leadership experience," or something like that.
