Empathetic, professional legal support

Marc provided excellent legal support in my divorce - I'm happy to have had him by my side during this difficult time. He was incredibly knowledgeable and empathetic. I appreciate how he simplified the intricacies of the process so I could understand the steps or decisions that needed to be made. He ...was committed to protecting your interests. Marc took the time to listen to my concerns and provided clear, practical advice at every step. He was quick to respond to my questions and made sure I understood all of my options. I highly recommend Marc to anyone looking for expert legal guidance during a divorce.

Everything you can hope for

So you know you need a lawyer, what you don’t know yet is that you need Marc, so after your done reading this I sincerely hope you call. Marc was referred to me by another divorce attorney and I am so glad that individual did so. Most important to me his entire approach puts any children involved f...irst which is all I wanted from the start. He is incredibly knowledgeable and patient in answering all of my questions while using all of his experience to guide you through the unfamiliar waters you are now in. Just know that should it come to it he will fight like hell for you in a court room for you. He is very responsive and timely with all communications. I am very sorry you are here, but Marc will be the friend and advisor you need during this time.

Committed and Professional

I can't thank Marc enough for the exceptional legal support I received during my divorce. He was incredibly knowledgeable, professional, and empathetic. Divorce is never easy, but having someone who truly understands the intricacies of the process and is committed to protecting your interests made al...l the difference. Marc took the time to listen to my concerns and provided clear, practical advice at every step. He was quick to respond to my questions and made sure I understood all of my options, which gave me peace of mind throughout this challenging process. What stood out the most was how much Marc genuinely cared about the outcome. I’m grateful for his support and highly recommend Marc to anyone looking for expert legal guidance during a divorce.

Compassionate and Tenacious

I am so glad that I had Marc on my side as council for my divorce. The process was drawn out and emotional. Marc consistently gave me great guidance, keeping me focused on getting to a fair resolution. He went above and beyond to be supportive and reachable, and coached me through the drama. His meas...ured approach and focus on details was reassuring. When the situation called for it, he was a tough advocate. He’s a kind, compassionate gentleman, but also a terrier.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
