“The healing journey always involves story. It is my goal to receive my patients’ stories and to work with them to create a dialogue that uncovers the deeper roots of the problem and the way forward. When I really hear the story, solutions often become visible. My personal passions for art, poetry, and nature inform my work on a daily basis. I appreciate the truth and beauty of the human experience with all its joys and sorrows, in times of new growth and in times of letting go that are part of the cycle of life. My own experience as a cancer survivor has deepened not only my empathy but my practical knowledge of what people really need during difficult times.”
