Welcome to

Law Office of

Thank you for stopping by my website. After trying cases and representing corporate clients at large institutions for over 30 years, I finally attained my long-delayed dream of opening my own law firm in December 2020. Why did I leave the comfort and security of “BigLaw” for the far more uncertain and precarious life of a solo practitioner? In a word, Freedom. Freedom from the conflicts of interest that are rampant in large law firms, freedom from the rigid hourly rate and fee structures imposed by BigLaw, freedom from the internal politics that plague all large organizations, but most of all the freedom to be able to represent individuals and small companies rather than Wall Street behemoths. If my experience and skills meet your legal need, it would be an honor to represent you. Please call me for a free consultation. Thanks again for dropping in.



Don Davidson is a trial lawyer with over thirty years of first-chair experience as an Assistant District Attorney in Manhattan under Robert Morgenthau, as an Assistant United States Attorney with the U.S. Department of Justice, as a Deputy General Counsel and Senior V.P. at UBS Financial Services, and as a partner with a trio of multinational law firms in New York and San Francisco. While Don relishes the challenge and excitement of trial work, he also recognizes that skillful negotiation and settlement are sometimes the best outcome for the client. Regardless of whether the case is to be tried or settled, the path to success always requires hard work, thorough preparation, winnowing the matter to its essence, and creative thinking. And, of course, the cost is always relevant, so efficiency is critical, too. Each case, client, and problem are unique, and one size most definitely does not fit all. Rather than taking a cookie-cutter approach, Don follows the unofficial USMC motto: Improvise, Adapt, Overcome. Let Don Davidson help you solve your legal problem.

Our Testimonial

FINRA Inquiry

Although my case was out of Texas, and my office is in Connecticut, I elected to work with Don Davidson for representation in a FINRA inquiry. When it comes to securities litigation, having someone with vast experience representing the big firms, and competing against them, is critical. While other attorneys were willing to take on my case, they offered little hope of a positive outcome. Don was able to manage my FINRA inquiry and ultimately obtain the result I was looking for. While he fought on my behalf, I was able to keep my practice running efficiently. Had we lost my case or settled, I would have been forced to seek employment outside of the securities realm, which would have been a major lifestyle change for me and would disrupt my clients’ investment strategies. Don periodically reaches out to me to catch up and discuss whatever is on my mind. I plan on being in the industry for 20 more years, and if I ever need securities law advice or representation, Don will be my first call.

Strategic Regulatory Attorney

I have been practicing law for almost 25 years and have worked with Don Davidson for the last 12. He is an incredibly knowledgeable and strategic regulatory attorney. We have sought his advice not just on examination and enforcement issues but also in helping us to understand, measure and mitigate risk. Don is not just a lawyer’s lawyer – he is an experienced and practical business partner that I can recommend without reservation. And finally, he is just such a pleasure and fun to work with – not easy to do that in this business!
