Dr. LeSon is a UC Davis-trained Orange County allergist-immunologist who practices with his heart.

He helps replace stress, fear, and anxiety in his patients and instills a sense of inner calm and peace by educating and inspiring them to take proactive steps toward health and healing. He has helped thousands of people transform their lives through the ways they think, feel, and act. His early childhood memories of the art of self-directed healing were reawakened when he opened his own medical clinic over twenty years ago. He believes the mind-body connection for health is best served through the practice of being centered and present in each moment. He is most proud of the praises that he receives from his patients who describe his style of practice as caring, compassionate, service, and excellence oriented.
