Outstanding service, got serious charges reduced to diversion
I have a child who was at significant risk of incurring serious charges for a mistake he made. In my initial consultation, Jonathan Datz was very candid and forthright in discussing services and possibilities, and additionally had contacts in the district attorney's office in which the charges would have been filed. Thanks to his work and personal outreach, the serious charges were reduced to diversion, which my son completed and has completed all diversion and required county involvement just months after an incident that could have waylaid him for years. Also as a result, 80% of my retainer was returned promptly--because there suddenly were no charges to fight. Can't recommend highly enough.

Mr. Datz a great choice in our defense
My wife and I live in Westminster Co, and about two years ago we were in crisis with a criminal and civil case. We were given a great referral from a good friend. We met with the Datz Law Firm to represent us regarding the civil case; and after our first initial consultation with Mr. Datz we chose his firm to advocate for us in court. We have been working with the Datz law firm for over two years now, and Jon has become a trusted friend, as well as a talented seasoned attorney. Mr. Datz has been there for us to defend us, to present to us circumstance and options so we can make the best decisions regarding our case. Jon has also shown us compassion when the emotional temp heats up in the courtroom. When things started to get rough for us, Jon has been there as a fortified defense attorney; at our side continuously. We would not hesitate to refer the Datz Law Firm to any individual seeking a well qualified attorney, who will stand along side of you in court. The Datz Law Firm will protect your morals and interest with integrity, solidity and confidence to do the right thing on your behalf, just as they have for us. We cannot say enough, as to how much we admire Jon and his outstanding firm. Regards, M. K. Thompson

Christopher Estoll
Christopher Estoll was our attorney from this law firm, he did an excellent job, and got our charges dropped without a trial.

Competent Lawyer and Honest
I found Jonathan Datz to be professional, very approachable and most importantly very honest in his dealings in my case involving a legal separation. His focus was client oriented and there was no sense of protracting things out to increase expenses which so often happens today in the legal profession. A client is really at the mercy of a system he knows little about an can be easily taken advantage of. Jonathan Datz is not this type of Lawyer. He used a timer to halt expenses when unexpected interruptions came by, not related to my situation. He also provided recommendations for mediators if I chose to go that route. not trying to hold on to my business but putting my interests first.
