IOD held an annual OD conference in Florida and internationally to attract OD Professionals. Global interest in OD was growing and attracting a new audience.
With the advance in online technology, IOD presented its first online session in 2010 which proved to be successful providing seven OD certification programs for a global audience. IOD offered OD Certifications online in India for several years through one of their partners. IOD has since hosted multiple cohorts and inspired the creation of an OD university in Ghana.
Given the rapid growth of IOD, starting in 2013, IOD welcomed some of the top facilitators, program managers, and educators in OD. Starting with Patti Dammann, who now leads IOD as its President. Patti has been at Nancy’s side for over twenty years as her advocate, partner, and best friend traveling around the world working to make a difference with OD.
Another invaluable addition to the IOD family was Susan Gervasi, who joined IOD in 2014, bringing her outstanding facilitation and instructional design skills.
