Message From the Director to our DUHS Clinical Laboratory Team

January 1st 2021

Dear Laboratory Colleagues;

I wanted to take just a minute of your time on this New Year’s Eve to say ‘Thank you’.  I could not imagine a better team and I truly appreciate your tireless dedication to our patients during a year where the demands on us were extraordinarily high.  You and your accomplishments through this pandemic fill me with great pride. 

In the week before New Year’s Day, I made a list of goals for the coming year.  Most of these goals are team goals for our labs.  Some of these goals are professional career goals for me in my various roles at Duke and few are just personal goals meant to make me a bit happier or healthier.  I’m sure that many of you do the same.  You will hear more about our lab’s goals later this year.  For now, we will continue to focus on the task at hand: staying healthy and providing timely and accurate results in the face of this pandemic.

This year, however, as I map out goals, I have the unshakable feeling that anything is possible.  There is no goal that could represent a bigger challenge for us than COVID19.  If we could continue to be successful in the face of a global pandemic, we can be successful in anything.  As you think about your New Year, make your lists, and plan out your ‘post-COVID’ life, I encourage you to think big.  Take the lessons learned and the new found strength from our pandemic response and build this into your tomorrow for our labs and for yourself.

With kind regards and optimism for an end to this pandemic and a brighter tomorrow.
