About

Experience. Integrity. Passion.

History

When I was old enough to run away from home, I spent countless hours on my own exploring the beauty of the back woods, local ponds, and vacant land in my neighborhood in suburban Massachusetts - always returning home in time for dinner. As a young adult in the 1970s and 80s, I took to backpacking in locations of grandeur from the Appalachian Mountains to the Rockies and Sierras, and everything in between. Coinciding with my "coming of age" was the realization that our industrial activities were polluting the Earth. But nothing about people's abuse of the environment annoyed me more than seeing trash, beer cans, and discarded gear and clothing spewed along a back country trail 25 miles from the closest town. It was then that I decided I would study environmental toxicology with the hope that some day I could contribute to the ultimate solution for environmental pollution.

After completing my postdoctoral training, I started my career by working as a toxicology manager for a small environmental health consulting firm in Oakland California. After about 20 months I decided that the direction the company was taking, along with a lack of opportunity to contribute to decision-making, had me reconsidering my career. I applied for and was hired into a civil service Staff Toxicologist position with the California State Health Department and thus began my 28 plus year career in State government addressing issues of chemical toxicity, consumer product safety, and public health. At the same time, I continued to work privately with nonprofit organizations and law firms providing toxicology consultation services for work outside of my purview as a State official, which I hoped would promote a healthier environment.

Right up until the time I retired from civil service in August 2017, I managed small and large governmental programs with legislative mandates to study the impact of toxic chemicals in people and the environment. It was fulfilling but somewhat frustrating due to the slow pace of change in government. But it wasn't until the end of my governmental career as the Director of Biomonitoring California that I pieced together the factors fueling my passion for my work. As with the trash polluting the winding mountain trails, I realized that chemicals are the "trash" polluting us. Only you can't easily see the chemicals inside our bodies so it is much harder to demonstrate that we are polluted. Running the biomonitoring program opened my eyes to many things but the primary take home lesson is that when we do look for the most toxic chemicals, we usually find them in our bodies.

It is with this knowledge, experience, and skill set that I offer my research and consultation services to continue to investigate how toxic chemicals harm people and the environment, and to continue to work on solutions to clean the chemical trash out.

 

Get in touch

Understanding the science of toxicology and its application in evaluating the risk of hazardous materials exposure and as it is used in regulatory settings is understandably difficult and convoluted. I can help sort through fact and fiction, including identifying fake science from real science. I want to help your organization, your community, your clients, and/or yourself with this process. Contact me so I can understand your needs, the scope of your problem, and how I can help you.
