Hello DIYers. I do a little DIY here and there on my PacNW home, and also know when to call in a pro. Much of my recent experience and background is in consumer product toxicology, especially in trying to prevent unnecessary lead (Pb) exposures. In previous lives, I worked at the US Consumer Product Safety Commission, Hewlett-Packard, and in academic research. Now I am into independent toxicology consulting. I'm hoping that I can contribute to your benefit on occasion.
