During the five years that I worked at Baxter Healthcare Corporation in Research and Development I made many presentations to upper management presenting new product ideas.
In my last year with the company, I was a member of the New Ventures Group that was dedicated to researching new product opportunities, writing proposals, and making presentations to upper management, with the goal of championing new product ideas into development by the R&D organization.
That experience, combined with my artistic training and illustration skills lead to my consulting work with various companies, creating new product proposals. Unfortunately, due to confidentiality agreements I can't show you that work. However, I can tell you that I am very good at it.
I'm also very good at creating slide shows. For an "mini" example, check out the slide show created for the Tribute to Jack Carey and Annie Hirsch, a couple that is cherished by the Swing Dance Community. The slide show presented at this event was thirty-five minutes long.
