I am a retired board certified diagnostic radiologist with many years of personal investing experience. We were fortunate to be able to provide more than 20 years of undergraduate and graduate support to our children who have multiple masters degrees, a law degree and a PhD. My undergraduate majors were advanced calculus and premedical chemistry, including qualitative analysis, quantitative analysis, general inorganic chemistry, and organic chemistry. I have an MD degree. I also have many years of experience in medicolegal jurisprudence and occasionally serve as an expert witness in medical diagnostic imaging, serving the defense side,and very rarely, the plaintiff side.
