I have had the opportunity to know Mr. Mark for a number of years and avail myself of his services a number of times. He is experienced and able to argue in different venues. He is warm and cordial and an excellent listener. I feel very comfortable when speaking with him, felt at home, and was able to understand everything.


Don, Thank you for your patience and kindness and most of all your professionalism.  It is very difficult to make these plans.  Because you broke it down for us, it helped tremendously to take one step at a time. You are the best of the best, Don!  Thank you so much for all you do so well!!!

Thank you for all your help these last seventeen months. I’m happier when I think about how things will be taken care of in the future. You and Caren are very sincere people. You both make it easy to relax and have a good conversation.


Mr. Mark’s robust resume is most befitting his courteous, professional demeanor in the dispensation of sound legal advice. We have found his counsel to be digestible, accurate & comforting. Beyond all of this, he is a caring, trustworthy expert who has always made maximum effort to remain current with our changing times.

We thank you and your staff for providing a comfortable experience with respect to estate planning. We are confident, that with your expert legal knowledge, we have the best strategic plan and legal instruments to protect our assets and our end-of-life wishes. You validate our questions and concerns, while seeking full understanding prior to providing answers with in-depth legal explanations and solutions. We are pleased with your accommodating and generous nature. It is easy to correspond with you by e-mail or phone. Your staff is extremely kind, knowledgeable, and provides us a positive experience with all correspondence.


For the past two years I have received documents on a regular schedule from the Law Office of Donald B. Mark.  I am a co-executor of my friend’s estate.  Every kind of communication has been sent to me and my co-executor with directions to call if I had any questions.  I have been impressed with the efficiency, competence and knowledge that Don B. Mark possesses.  He has dealt with the State of NJ regulations, financial institutions and accountants.  With all of them, he was mindful of my friend’s wishes to donate her assets to charities that were important to her.


Thank you for all your hard work in settling Rob’s estate. 


Thank you for all of your help with our legal needs.  We truly appreciate everything you’ve done.

Oh my gosh, I knew you were a nice man when I met you but your generosity – I’ve never met anyone as generous. You are so wonderful and I’m so grateful! Thank you for making this transaction so easy.
