“I have found that the deepest learning comes through suffering and the loss of hope. Most of us find it hard to be still, rest, look within, and ask for help to calm the storm that rages. My desire is to offer a “safe harbor” for people to heal as they take personal inventory and feel the breeze of grace. Frederick Buechner put it this way: “Listen to your life. See it for the fathomless mystery it is. In the boredom and pain of it, no less than in the excitement and gladness: touch, taste, smell, your way to the holy and hidden heart of it, because in the last analysis all moments are key moments, and life itself is grace.”

“I have been married to my wife since 1978. I have five adult children, two amazing daughters-in-laws, and four grandchildren. I love reading, running with my wife/friends, family dinner parties, traveling, and retreating for times of prayer, contemplation, silence, and solitude.”
