Returning from a trip, I tested positive for Covid. Dr. Wellisch was the physician on call that Saturday. He returned my message with the answering service within 10 minutes and was very thorough in describing the care and possible treatment with Paxlovid, for example. Again, on the following Monday, when I felt worse, his response was the same.  He was most caring and compassionate in his style as well -always appreciated when you feel miserable..
