Daniel J Mitchell


Here’s why you’ll enjoy working with him.

The co-chair of Bernstein Shur’s Litigation & Dispute Resolution practice group, Dan represents businesses and individuals in a broad range of matters, from large-scale commercial litigation to significant personal injury cases. Dan also uses his expertise in data security and privacy law to advise his clients on dealing with a host of issues in these emerging areas. With over two decades of litigation and trial experience, Dan has an in-depth knowledge of the state and federal courts and is widely respected as a confident, compelling, and ethical counselor.

But that’s not all. Dan is also very experienced in:

  • Disputes involving securities brokers and their customers
  • Products liability cases
  • Cases brought before Maine’s Business and Consumer Court
  • Consumer class actions
  • Civil claims brought under the Racketeer Influenced and Corrupt Organizations (RICO) Act

In his former life, Dan:

  • Served as a law clerk to the Honorable David G. Roberts, associate justice of the Maine Supreme Judicial Court
  • Was on the legislative staff of US Senator John H. Chafee (R-RI)

When Dan isn’t working, he is…

Spending time with his wife and two sons, especially if it involves hiking or fishing anywhere in Maine. Dan and his family are very active in their church and he is a former member of the Board of Trustees of the Catholic Foundation of Maine.
