  • We are the world’s largest medical device manufacturer with a substantial presence in California and large portfolio of legislative and regulatory concerns. Carpenter Sievers has done a tremendous job representing our company’s interests in the Capitol on issues ranging from chemical bans, to public health program coverage of our products, to local facility permitting and zoning challenges. In addition to aggressive representation, they have always operated in an ethical manner that is sensitive to our corporate and brand reputations.

  • Carpenter Sievers represented the EveryLife Foundation, a patient organization dedicated to families whose children are born with rare genetic disorders, in the effort to create a new law requiring newborn screening for rare diseases of all babies born in California. My son, Zack, has Pompe disease and I came to Sacramento on several occasions to meet with legislators and tell Zack’s story at committee hearings. I was overwhelmed by the professionalism, skill, unwavering commitment, concern and compassion for the kids and parents displayed by the Carpenter Sievers lobbying team in relentlessly pursuing our goal. We not only passed this legislation into law, but this landmark bill is now being used as a national model to pursue similar legislation to help children and their families in other states.

  • Carpenter Sievers has represented our association for more than a decade. They not only do a terrific job of advocating for us in the Capitol, but they are also excellent strategists who represent us with passion and integrity. And they are more than mere lobbyists; they operate as an extension of our staff. They have helped us plan, assisted in developing our messaging and communications activity, developed political action plans, and have been invaluable resource with our members.
