Comment - “ He listens, he explains, he does... ”

He listens, he explains, he doesn't rush but waits on me before we finish. He pays attention to my concerns.

Comment - “ Healing ”

He listens, acts and cares with an amazing human touch. I am blessed he is my doctor. There is a reason everyone wants to be his patient: he offers solutions and plans rather than just a bunch of pills.
