Expertise in Securities Litigation

I worked with Andrew S. May on a complex securities compliance matter, and his 30 years of experience were immediately evident. His deep knowledge of regulatory enforcement and customer disputes was invaluable. While his case strategy was top-notch, I wish the communication could have been a bit more timely at times. The outcome was favorable, and I appreciated his ability to navigate the nuances of securities law. Recognized by Best Lawyers in America for Litigation - Securities, his expertise is undeniable. The minor delays in response were the only drawback in an otherwise outstanding experience.
