About Mark

My name is Mark W. Leach. I am an attorney with a Master’s in Bioethics.

I have presented at international, national, regional, and local conferences for obstetricians, medical geneticists, genetic counselors, bioethicists, and Down syndrome support organizations. I have been published in professional journals, national and local newspapers, and on-line blogs. This blog is a continuation of my efforts to provide perspective and resources for informed decision making for those involved in the administration of prenatal testing for Down syndrome.

I serve in various volunteer capacities for several non-profit organizations devoted to providing education, support, and health care to individuals with Down syndrome and other intellectual and developmental disabilities. I am also a staff member with the National Center for Prenatal & Postnatal Down Syndrome Resources. All of the views expressed on this blog are entirely my own and should not be attributed to any organization with which I am associated.

My wife and I have two kids. My daughter is endowed with Down syndrome and my son is endowed with curly blond hair. We live in my hometown, Louisville, Kentucky.

In my spare time, I enjoy taking the family to watch our Triple-A baseball team, the Louisville Bats, handicapping the Kentucky Derby to various degrees of success depending on if Calvin Borel finishes in the money, catching live music at club-sized venues, and bourbon. I also try to buck the trend by not being an annoying UK basketball fan, but a fan nonetheless.

    You must be a KIKE, Nigger, asshole, dumbass, chose the appropriate response. Are you offended?, GOOD!. The skin of everyone is way to thin today. Put on some BIG BOY pants and get a life!

    • Always love these types of responses, since apparently it struck a nerve with you. Instead follow your own advice and either (a) use those terms in your workplace to see if your employer thinks it’s thin skinned to impose consequences for slurs; or (b) get a life and move on from blogs you take offense at.

      • Love it Mark that you actually take the time to respond to those that are uneducated in today’s society.

    This is a fantastic site. Thank you. I hope you don’t mind me borrowing your term ‘endowed with Down Syndrome’, it’s so apropos. One of the best friends I have in this world is endowed with Down Syndrome and so very much more!
