Don Hayden


Mark Migdal & Hayden

"Mark Migdal & Hayden prides itself on our firm culture which is premised on promoting diversity and inclusion in our team and in the workplace as a whole.  MM&H is proud to be a part of Equality Means Business."

Although age is just a state of mind at MM&H, with thirty-two years of experience as a commercial litigator and a reputation as a seasoned practitioner in the international arbitration arena, Don has been around the block (and the globe) a few times during his career. Don prides himself as being a trusted advisor who can evaluate complex claims, especially for those clients who find themselves in multiple jurisdictions given today’s global economy.

Don has been ranked in Chambers & Partners since 2009 for commercial litigation, and has been regularly recognized as a top attorney by Best Lawyers in America, South Florida Legal Guide, Florida’s Super Lawyers, Florida Trend Legal Elite and the Legal 500 for either litigation or international arbitration. In 2010, he was inducted as a Fellow of the Litigation Counsel of America.

Over the years, Don has represented AT&T, Knauf Plasterboard, Borg Warner, Banco do Brasil, Travelers Insurance, Google, and SAP to name a few. 

Throughout his career, Don has been committed to pro bono representation. He served as the Chair of the widely recognized Pro Bono Program of Baker & McKenzie in North America for over seven years. He co-counseled with Lambda Legal in Langbehn v. Jackson Memorial Hospital, a high- profile case that led to an executive order by President Obama requiring all health care facilities receiving federal funds to have equal visitation rights for same sex families. In addition, he was involved in the drafting of an amicus brief on behalf of leading juvenile rights organizations, in Gill v. State, which led to Florida courts overturning the state’s prohibition against homosexuals adopting, and in Windsor v. the Internal Revenue Service, he assisted in drafting an amicus brief on behalf of Fortune 500 companies in favor of marriage equality. He also was awarded for his work in the areas of foster care and juvenile justice by Lawyers for Children America and the Miami-Dade Public Defender’s Office.
