Mr. Zulack is a co-founder of our firm. He began focusing his practice over 25 years ago on cross-border and international commercial litigation and dispute resolution.

Mr. Zulack has represented Swiss, French, Luxembourgeois, German, Italian, British and Austrian financial and commercial entities in disputes and lawsuits in U.S. courts. He currently represents more than 20 European banks and investment funds that are being sued in New York. Mr. Zulack has worked closely with law firms in Geneva, Zurich, Lausanne and Paris. From the outset of the firm’s international practice, the firm decided to collaborate and cooperate with law firms in Europe rather than to establish an office in a European city, as many large U.S. and U.K. firms have done. Mr. Zulack has traveled to Europe to meet with clients and their European lawyers approximately four times a year over the past 25 years. Mr. Zulack has represented individuals in divorce proceedings since the founding of the firm. He now limits this aspect of his dispute resolution and litigation practice to high net worth individuals who require a lawyer with substantial financial experience and sophistication.

After graduating from the University of Michigan Law School, he received Fulbright, Ford Foundation and C.R.B. fellowships to pursue post-graduate studies in Belgium. Mr. Zulack speaks French fluently. He is a Past Chair of the International Section of the New York State Bar Association and is a current member of the Executive Committee of the Section.
