Capitol Weekly’s Top 100: Mark Weideman

53. Mark Weideman

Mark Weideman’s namesake lobbying firm, The Weideman Group, represents a wide variety of the biggest name interests in California. With all those heavyweights it is no shock his firm consistently ranks among the biggest lobbying revenue generators in the state. And there is a good reason he has all those clients – his relationships in the Legislature and Administration run deep and his engagement on issues is tenacious, professional and highly effective. Most of all, he can easily walk the high wire between labor giants like SEIU and business titans like Blue Shield of California, AARP, Autodesk, Carnival Corporation, McKinsey & Company and…ah, you get it. Weideman has also played a major role in enactment of laws that, among other things, created the California Wildfire Fund and massive healthcare budget efforts like the expansion of Medi-Cal to previously ineligible populations. He previously served as an officer of Blue Shield and AT&T and practiced law with the international firm Pillsbury as well as with the Sacramento-based firm Wilke Fleury. He obtained his undergraduate degree from UC Berkeley and his law degree from Hastings College.
