I would like to build a strong long-term relationship with each patient by providing a comfortable environment and friendly support during their visits. I have lived in the Seattle area for more than 14 years and studied Art (Oil Painting) in college. My family and I live in the woods with many kinds of wild animals, such as salmon, beavers, deer, raccoons, and sometimes a bear. Walking in the woods and discovering nature is one of my favorite family activities.
