Jay joined Abbott Laboratories in 1975 and had a marvelous career spanning almost 25 years, taking his family around the globe, making stops in Germany and Japan before returning to Chicago in 1992. Jay retired from Abbott in 1999, however, Jay never really did retire. He became a trusted mentor to many.

Despite being diagnosed with Parkinson’s Disease in 2014, Jay continued to push himself both mentally and physically to keep the disease at bay.

Jay had many passions, including photography, playing golf as well as socializing and traveling with friends, but his favorite was watching his grandchildren grow and thrive! Jay was always very generous and saw the best in everyone.
