Message from the Chief Medical Director:

Certainly, there are many who will experience a serious illness or even death in this pandemic.  Many will suffer significant financial burdens.  Far more will experience very annoying inconveniences.  The government, healthcare administrators and care providers as well as public servants and volunteers’ efforts are directed to mitigate all of these problems. However, it is also through these trials and tribulations that characters strengthen, opportunities for charity are provided, and prayer can become a very powerful part of the care plan.  Good can emerge from where no good is apparent.  Prayer is the lifeblood of Mission of Mercy; and as we pray for all our Mission of Mercy family and all in the world, we ask that you pray for us!

God bless!

Dr. Michael Sullivan, MD

Chief Medical Director
