Happy Anniversary Dr Nguyen in heaven! Thank you for watching over us! I am pretty sure you have something to do with this... we recently found a magna cum laude cardiologist who is practicing here in NJ!!! And a Harvard graduate at that! It is you who does not want us to go to N.Y. to get the best care. Thank you Dr Khanh. To date I still speak & share about how good you are...

We were first time parents and stressed at what awaited our son. my husband even...

My son, Michael, was born with a right aortic arch which was discovered during a sonogram five months before his birth. His pediatric cardiologist from Columbia-Presbyterian Children´s Hospital told us that if he should ever need surgery, Dr Nguyen was the absolute best doctor we could hope for to do the surgery. All was good until the winter of 2018-2019, when my son who was now 11, began having pain in his chest cavity. I immediately knew what this was. His pediatric cardiologist in Orange...

15 years ago, Dr. Nguyen performed heart surgery on me for my heart condition called coarctation of the aorta. Now, I am soon to be 23 years old and live a perfectly happy, healthy life. So sorry to hear about Dr. Ngyuen's passing. Such a big loss as he was an extremely talented, kind, and wise soul. Thank you! Rest in peace <3
