Washingtonian magazine featured Arnold & Porter partners Cara Koss and Thomas Richardson in its 2026 “Top Financial Adviser” list. The list serves as a guide to “the area’s best financial planners, investment advisers, tax accountants, and other money pros.” To compile the list, Washingtonian surveys legal and financial professionals across the D.C. metropolitan area and supplements those results with independent research and input from industry experts and publications.
Cara leads Arnold & Porter’s Private Client Services team and focuses her practice on advising high net worth individuals, both domestically and internationally, on a wide range of sophisticated matters including estate planning, trust and estate administration, lifetime gifting, family office formation and counseling, asset protection, business succession planning, and tax compliance.
Thomas advises on a range of wealth planning matters, including estate planning, estate and trust administration, representation of family businesses, tax controversies involving the Internal Revenue Service and local tax authorities, and fiduciary litigation.
