Diana Marianetti works with clients in all stages of life to plan for both the expected and the unexpected when it comes to estates and business succession. Whether assisting a young family to create their first estate plan upon the birth of a child, planning an exit from a family-owned business, or helping resolve a dispute upon the death of a family member—Diana helps clients think through the key considerations, define priorities, and accomplish their goals. She particularly enjoys helping young families and women business owners, who so often neglect this critical aspect of their success. Diana also regularly works with families of persons with special needs to plan for the future with supplemental needs trusts and special needs trusts.

As a member of both Maslon's Estate Planning Group and Maslon's Trust & Estate Litigation Group, Diana offers clients a unique perspective across a broad spectrum of needs. She is highly skilled at creating comprehensive estate plans that minimize the risk of future disputes as well as in advising clients on issues regarding fiduciary duties, trusts, and probate when litigation simply cannot be avoided.

Diana also takes an active role in advancing her profession, the marketplace, and the community. Since 2014, she has served as an adjunct professor at Hamline University School of Law, teaching a "Wills & Trusts Skills" course. Diana also frequently presents on key topics in estate planning to members of the profession, clients, and the broader business community, and she regularly serves as a pro bono volunteer to provide legal services to those who otherwise might not have access. She is an active member of Women President's Organization, a non-profit membership organization for women presidents, CEOs, and managing directors of privately held, multimillion-dollar companies.
