Datz Law conducted the sale of my South End apartment smoothly and professionally throughout the process. Lawyer Michael Clancy was aggressive in negotiation and patient with me as we discussed the transaction. He was also very available to talk whenever I had questions. Vered was efficient and informative in processing the closing paperwork.

Our experience with David Datz and the entire staff at Datz Law was awesome. From the first (free! :-) consultation, we knew we were in good hands. Datz represented us on the buyer's side in a real estate deal that was not a cookie cutter purchase. David and his Associate Michael Clancy were incredibly detailed and diligent about protecting our interests. I cannot say enough good things about Michael Clancy. Words escape me. He was phenomenal. And Jim, who answers the phones always made sure we were either able to reach Michael or David or got a prompt return phone call. That's another great thing about Datz Law... they answer the phones!!! No one does that anymore. Datz Law does. I HIGHLY recommend them.
