Three Katten attorneys were named to Citywealth's list of the Top 100 International Powerwomen 2026, including Private Wealth Partners Ronni G. Davidowitz, Bonnie Lynn Chmil and Kathryn von Matthiessen.

Citywealth's annual list recognizes 100 leading women in private wealth across 17 jurisdictions, including professionals in law, tax, fiduciary services, private banking, investment, art advisory and family office services. The 2026 list reflects the issues shaping global private wealth, including international relocation, inheritance tax planning, family governance, succession, trust restructuring, digital assets, philanthropy and geopolitical uncertainty.

The Head of Katten's New York Private Wealth practice, Ronni, helps clients address the legal, business, tax and personal issues involved in estate planning and wealth management. High-net-worth individuals, closely held businesses, entrepreneurs, artists and art collectors rely on her for creative and efficient planning, as well as guidance on estate and gift tax audits and litigation, Surrogate's Court contested matters and the creation and administration of public charities and private foundations.

Bonnie advises high-net-worth individuals, families and fiduciary trust companies in often-sensitive private client disputes, balancing extensive commercial litigation experience with an understanding of the needs and expectations of private clients and fiduciaries. She focuses on clients' desired endgame from day one, helping them pursue quick and practical resolutions through negotiated settlements or effective litigation tactics in matters involving estates, fiduciaries, real estate, commercial contracts and business torts.

Kathryn provides sophisticated yet practical counsel to ultra-high-net-worth individuals on income and transfer tax optimization, estate planning and business succession planning for domestic and international private clients. She advises on pre-residency planning for clients coming to the United States, outbound planning for clients leaving the United States, tax-efficient wealth transfers for foreign families with US members and global succession planning involving assets such as operating businesses, hedge fund interests, real estate, intellectual property and artwork.
