Michele’s private client roster has included several of ArtNews’ Top 100 Collectors, such as The Paul G. Allen Family Collection, along with many emerging and seasoned collectors. Her advisory focus is on mid-career to established, blue-chip artists represented by reputable galleries and museums worldwide.
