Dr. Michael DiBartolomeis’ extensive toxicology and public health expertise, many years of experience, and exceptional expert reports and testimony have been key to resolving a number of difficult cases involving toxic chemical exposures that I have been honored to litigate. More importantly, however, Michael leaves the clients and communities he works with better than he finds them. From meeting with individual clients to entire communities, Michael has been instrumental in helping each of my clients (and their attorney) to understand complex toxicological subjects and the impact on their lives.
— Kyle Smith, Smith|Law, Founding Member

For the past ten years, we have relied upon Dr. DiBartolomeis’ extensive knowledge and steadfast integrity to provide toxicology and exposure assessment in evaluating health and environmental risks of toxic materials in a variety of consumer products. His expertise has been instrumental in our litigation to force corporations to remove harmful chemicals from their products.
— Andrew Behar, CEO & Danielle Fugere, President and Chief Counsel, As You Sow

There are many smart toxicologists. And there are experts who advocate for health, especially for the most vulnerable in our communities. But Michael DiBartolomeis is a rare combination: he possesses superb scientific and writing skills, and he is energized with passion, empathy and caring. His contributions have been remarkable.
— Richard J Jackson, MD MPH, Former Director National Center for Environmental Health, Former California State Public health Officer

Alumni such as ... Michael DiBartolomeis are good examples of students from the eighties who have gone on to become nationwide leaders in toxicology.
— Building for the Future: Toxicology Training Centers, Society of Toxicology, 2011

The work you are doing to protect and promote public health in California is of great importance and results such as those of the Safe Cosmetics Program add tremendous value to the national conversation on chemical policy.
— Hon. Henry A. Waxman, Ranking Member, House of Representatives, 2012

Dr. Michael DiBartolomeis has been an incredible resource providing his expert knowledge of toxicology and environmental sciences to inform community-based efforts to impact environmental and occupational policies. His scientific guidance on chemical exposures for nail salon workers helped to advance groundbreaking policies as well as much-needed community education for vulnerable workers, many of whom are immigrants.
