Five Kostelanetz Attorneys Also Named Leading Lawyers for High-Net-Worth Private Clients
NEW YORK (July 27, 2026) — Calling Kostelanetz LLP “one of the most elite tax firms in the U.S.” and “one of the go-to tax litigation firms in the country,” Chambers and Partners has recognized Kostelanetz as a top-tier, Band 1 firm for high-net-worth private tax clients in its 2026 High Net Worth (HNW) Guide.
In addition to the firm’s selection, Frank Agostino, Megan L. Brackney, Caroline D. Ciraolo, Michael Sardar, and Bryan C. Skarlatos have been recognized as leading lawyers for high-net-worth clients in the category of Tax: Private Client.
Chambers notes that Kostelanetz “is widely admired as a leading firm for contentious tax matters. The firm also handles significant tax planning, compliance, and structuring work for high-net-worth individuals and closely held corporations.”
Chambers also highlighted several testimonials regarding the firm’s work with high-net-worth clients:
- “Kostelanetz are our go-to: we call them when things go sideways. They take over in a very professional and appropriate way. They are respectful, they know the law, and they know our options. They have language that we don't have, and the IRS respects them for that.”
- “It's a large team at Kostelanetz and based on the work they are doing and I think by every other measure, they are extraordinary: the people, the thoughtfulness, the creativity. They are exceptional. They are leaders in this practice.”
- “They are one of the go-to tax litigation firms in the country.”
- “Every member of the team with whom I have worked has been a skilled and knowledgeable practitioner.”
In ranking five Kostelanetz attorneys for Tax: Private Client, Chambers also highlighted their deep experience representing high-net-worth clients in complicated and high-stakes civil and criminal tax matters.
Of Frank, Chambers noted that he “has substantial experience representing high-net-worth clients in tax disputes,” and that he joined Kostelanetz recently. One person told Chambers, “Frank is a legend for his legal acumen and commitment to the tax community. He's truly the best in the space.”
Of Megan’s work, Chambers said she “is rated by peers as someone who can take on the most sophisticated of tax issues.” One person told Chambers, “Megan is most responsive, competent, and reliable,” while another said, “She is my go-to; I can't speak highly enough about her.” In another testimonial, Chambers states, “Megan is incredibly talented and very involved in this work. She is very, very good.”
Chambers testimonials state that Caroline “is probably the hardest-working woman in show business! She is just excellent, cares deeply about her clients, and spares no effort in attempting to get the best result for them.” Another said Caroline’s practice resides “at the intersection between criminal and civil matters in the ultra-high-net-worth space.” Yet another declared, “She is a star. She knows everything there is to know and has really contributed to the making of this firm.”
In ranking Michael, Chambers noted his representation of “individuals, families, and corporations in matters relating to IRS investigations and controversy matters.” One testimonial stated, “Michael is the strategist. He is the creative one, thinking, let's try to offer the IRS this resolution, and what the implications will be. I respect him deeply.”
Chambers’ testimonials describe Bryan as “on every level so far above anyone else I have encountered in this field. His ability to deliver is extraordinary. He is brilliant, and nice.” Another commenter said, “Bryan has created the most elite tax firm in the US. Truly perfect.” Others told Chambers, “Bryan is just really, really clever with strategy. He is also very good at client service and very hard-working.”
In June 2026, Chambers recognized Kostelanetz and eight attorneys in its 2026 USA Guide in the areas of tax controversy, tax fraud, tax law, and white-collar defense and government investigations. The eight partners recognized in the Chambers USA 2026 Guide include Megan, Caroline, Bryan, Frank, Christopher M. Ferguson, Sharon L. McCarthy, Jay R. Nanavati, and Todd Welty.
