Very honest about the situation at hand. Felt extremely comfortable bringing up any concerns or questions when I didn’t understand things.
"Neil Is the type of opposing counsel that I wish I had in all my cases. He is smart, calm, and collected. He advocates well for his clients. He is courteous and professional. Our profession should be about civility and ethics, which Neil exemplifies in everything that he does. He is an example of what every lawyer should be like, and how they should present themselves."
"I can recommend Neil Opdahl-Lopez as an Attorney who cares about his clients and represents them zealously. He is a tough adversary but professional in his adversarial role. Neil Opdahl-Lopez looks to find ways to settle cases and is creative in finding solutions. I have had several cases against him and highly recommend him."
"I have known Neil for a very long time and he never wavers in pursuit of zealously advocating for his clients. He is a consummate professional in addition to being a genuinely decent person. Whether it be in service for our country as a Marine or in service as an attorney and counselor for his clients, he will always exceed expectations."
"I endorse this lawyer. Neil Opdahl-Lopez is an experienced criminal defense Attorney who gets things done! Neil is at all times professional, competent and on time. I refer any criminal defense cases to Neil because he gets cases dismissed or sentences reduced. Neil is my "go to" defense Attorney. I highly recommend him."
"I have observed Neil's work for years. We originally stood across the aisle from each other on criminal cases in the military. Neil is truly a conscientious, detail-oriented, earnest, and genuine advocate. That is invaluable to any client. You can trust Neil to not only dedicate himself to your case, but to ensure no stone is left unturned until you get the best result. Since opposing Neil, I have trusted him to handle matters within his field for my family, which he won. Neil has the qualities that so many Clients find lacking in their counsel. When he takes your case, he puts himself in your shoes and fights it as though it was his own."
"Neil is the kind of conscientious attorney I am more than happy to endorse to clients looking for a real advocate. In the field of family law, it is important to have an attorney who can work well with opposing counsel while zealously advocating for a client’s welfare. Neil has the right kind of personality for this work. I have consulted with Neil on more than a few occasions and have always been impressed with his commitment to his clients and the law. That commitment means Neil will get his clients the right answer before responding; this is all too often an overlooked vital quality in a legal representative. Neil is competent, smart and kind, qualities I believe make him an easy choice for peer endorsement."
"I've known Neil for quite some time now. I know Neil as honorable, hard working, result-oriented and friendly. I've had occasion -- indeed, the honor -- not only to work on various cases with Neil but also to mentor him to some extent. It's been a pleasure throughout. Neil is straight up and seeks to get the job done -- and done well. Neil will go far as a lawyer. I recognized that upon meeting him for the first time. When I shook his hand, and when we got to talking about his military career and making the transition to the law, it was clear to me that he was focused and determined. Working hard and treating people well comes naturally to Neil. He was, as the old cliche goes, "raised right." He comes from a really nice family (which is also vitally important to him), and he has the intellect, courage and honor to go far as a lawyer. Indeed, he's doing so right now. I endorse Neil without reservation. -- Mark McBride, Esq., Beverly Hills, California"
