We highly recommend Dan Marr
We had a complicated real estate issue and needed a lawyer with experience and expertise. We hired Dan after researching and interviewing a number of candidates. Dan stood out from the group. He laid out a strategy right away and succinctly explained the steps. He succeeded in quickly resolving the case as described. Dan is a pleasure to work with and extremely responsive. We chose to communicate mostly through emails which were always promptly answered. To our delight, even emails we sent late in the evening were answered by 6:30am the next morning! We highly recommend Dan regardless of the complexity of the case and we now use his services for both commercial and personal business.

Straight Shooter
Dan was a great help with a direct and professional approach during recent ownership changes/corporate transition and new offer negotiations. He was a straight shooter with his approach- evaluating the content and implications within the document, recommending and modifying content with my unique considerations in mind. His awareness of career path timing, frank discussion and understanding of corporate transitions allowed him to craft a workable solution for my situation quickly.

I highly recommend Attorney Dan Marr
I highly recommend Attorney Dan Marr to anyone seeking a lawyer who will get the job done fairly and efficiently and with the highest level of expertise. Dan recently assisted a sibling and me in resolving a complicated dispute related to a family trust and ownership of a family home in NH. He successfully found a path forward that avoided litigation and resolved the issue in a matter of months. He listened to us, he brought expert knowledge into the situation, and he succeeded where other lawyers we consulted had failed to find a solution. He was efficient with time and very easy to talk to, and he is an excellent negotiator. In my experience Dan ranks at the very top in his areas of practice. I am deeply grateful that we located Dan Marr and were able to benefit from his expertise. I recommend him most highly. -J.P.

Outstanding Legal Advice and Service
I am the owner of an independent manufacturer’s rep agency. For several years, a long term NH based principal was delinquent in paying commissions. After putting up with this situation for years, I contacted Dan for help. He quickly obtained an Attachment. When the principal filed Chapter 13 Bankruptcy, I learned the value Dan’s insight and instincts. He protected my interests during this complex process. The company has since emerged from Bankruptcy and is making scheduled commission payments. Dan has excellent communication skills and is prompt to respond to calls and questions. I have confidence in Dan’s law acumen.
