Excellent Service. Highly Recommended. The Diamond Law Firm took my estate litigation case when a prior law firm dropped me due to their lawyer leaving. I was shocked. I had called many other firms who would not take over my case before I was recommended to The Diamond Law Firm. I knew my case was extremely complicated and the odds were not in my favor. They were able to get my case resolved to my satisfaction. Thank you to everyone at the Diamond Law Firm. I highly recommend the Diamond Law Firm.

Sandra Diamond and her associate Rachel Oliver were thorough, efficient, and fast. We started my estate planning as the city was shutting down. We were able to do virtually everything via email and calls. My trust and other estate documents were wrapped up in less than two months. They were incredibly responsive and were able to promptly answer any question I posed. I’ve just paid their invoice and am convinced that they’re the best deal in town.

Ben Diamond is an excellent lawyer. He has given me very helpful advice in preparing my estate plan. I am a lawyer myself but don’t practice in this area of the law. I highly recommend him.

The Diamond Law Firm did a fantastic job in setting up my trust and estate documents. Rachel and team were very professional and took time to make sure everything was set up just the way my wife and I wanted. Thank you so much!
