Michelle Weddington

Greetings PMI—Southern MD Chapter…

I would like to share very briefly that though I am a native of Maryland, I have also had the pleasurable opportunity of holding residence in various locations ( most recently Iowa-10 yrs!--- 5 other US states, Montreal, QC & Brussels, Belgium) & now returning to the DMV with an expanded cultural & experiential diversity.

Professionally, I hold an M.B.A. from the University of Maryland and a few undergraduate degrees and certifications, and of course, a member of the Project Management Community. I greatly enjoy working as a Management Consultant (10+ yrs) and have been opportune to serve in a varied listing of arenas and industries, from NGOs & legal to education and healthcare. In earlier years, I served as a Registered Nurse and later transitioned into Business, Management & Consulting. Now as part of my company, I greatly enjoy planning/constructing events & using innate creativity in both professional and domestic settings. The events range from office seminars and university symposia to international business conventions. (etc.)

My beginnings were from a relatively large family, with a very rich heritage and consisting of five other siblings. I am a dual, US/Canadian citizen. I have light linguistics in Spanish & French and am pursuing fluency, as I celebrate diversity and culture.

I am glad to now serve as a new PMISOMD Board member and hope to grow further and contribute all I can to the organization.
