Martin (Mort) Schmidt, CPG to Retire in December

Our good friend and colleague, Mort Schmidt, will be retiring from Cox-Colvin & Associates, Inc. at the end of December. I have known Mort since we were both geology students at Ohio State in the (gulp) late 1970s. Many of the rest of us at Cox-Colvin have known and worked with Mort for most of our working careers beginning at Geraghty & Miller in the 1990s. For the past 21 years with Cox-Colvin, Mort has been a trusted teacher to new staff, a respected consultant to our many clients, and a recognized expert in the field of vapor intrusion to the consulting and regulatory community at large. We will miss both his guidance and his infectious sense of humor. Please join us in wishing Mort and his wife Nancy a long, happy, and adventurous retirement by emailing him at
