Susan Neal

Susan’s background as a Litigation Executive Assistant in the law firm environment set the foundation for her eventual transition into the corporate world and ultimately to McLennan Design.  First supporting as Executive Legal Assistant to the Chief Legal Officer of Wamu for ten years prior to its acquisition, and then as Executive Assistant to the Global Chief Procurement Officer of Starbucks at its Seattle Headquarters.   This led to the venture capitalist connected role as Executive Assistant to the CEO of a high profiled scientific health and wellness startup based in Seattle.

Inspired by McLennan Design’s mission to help make the world a better place, she balances her work with writing projects supporting a variety of causes, including a horse rescue sanctuary.  Apparently she spends so much spare time with horses, she has now subconsciously taken to color-coordinating her outfits with their own coloring and tack!
