Highly recommended!
Am very happy with my working with Jason Lamm! He took on my case on short notice then worked with me over the course of around two years until things were taken care of. I recommend him very highly!!

The best!!
I am so so appreciative for Jason and his professionalism and knowledge. I have never had contact with the criminal justice system and simple a fish out of water. He and Katheryn at his office went and above. They explained everything very well, were so reassuring, hand held me through the process and above all else were ethical, professional and delivered. I am forever grateful to he and Katheryn Andy would highly highly recommend him to anyone. While he has a speciality of criminal defense, I am confident in his capabilities of overall anything legal. Thank you Jason for all you’ve done and all you do for others!

5 stars all the way for Jason Lamm
I found Jason on a Google search and did my due diligence on him and everything just felt right so we hired him to help my partner with a legal battle, right away Jason already knew how to approach this case and explained the steps we will take together for the best out come. In a time of high stress Jason really understood and took the time to give us a full scope of what to expect, what could happen, and what his job is to help us. He's not like other attorneys you talk to that sound like you're wasting "their time" and want to get off the phone with you as quick as possible, no not Jason he will stay on the phone and even call you back when he's not at the office so that you're comfortable and have all the questions you have answered. At court he’s intelligent and has the poise that really stand outs than the rest. He knew how to handle this case and the outcome of it was better than we were even expecting! Hands down the best attorney. If you want results Jason is worth it.

After facing two F4 felonies in Pima county, Jason got one thrown out and the other reduce to a misdemeanor, I'm not saying all cases will inherit the same results, but rest assure this lawyer will work tirelessly for you.

Great at what he does!!!
After being highly recommended by another lawyer he dedicated his time to go through my file/history to really get to know not only my previous case, but myself as an individual as well as where I was at in my life thus far. He was very knowledgeable, upfront, and direct about the things that might come up and about the things that did come up. However, he always took the time to explain things thoroughly in a way that I could understand since I am not familiar with the language of the law. Jason was easy-going, which allowed me to be able to open up to him and establish that trust, but he was serious and ready when it came to showing up in court. The outcome of my case was positive and I feel like I got a second chance at life because he pushed me to see things through when I wasn't too sure about them myself. I would highly recommend Jason Lamm to anybody who needs dependable and trustworthy legal council in their corner.

Brillant, Stellar, and tactical! A Superman attorney to have for anyone in any serious criminal matter.
There are no words available in English to describe how pungent, brilliant, and tactical Jason is. Jason was recommended by a friend of mine when I needed a strong attorney to represent me in a serious criminal matter. When anyone is in a situation where it appears that here is no hope, no avenue for relief, no conceivable approach to positively and victoriously resolving any serious criminal matter; think again and call Superman! There is a mountain against me in court and the pressure is unparallel in my life currently; yet, thanks to Superman Jason D. Lamm, I see the light in the darkness around me. Jason, has in many perspectives provided aid, comfort, and calm through my ongoing criminal matter. Yet, most importantly, his intelligence, aggressiveness in court, and strategic, methodical tactics has allowed me to realize that a victorious outcome is very real. I feel privileged that Jason is my attorney. While my case is in progress, it is indeed assuring to know that Superman Jason D Lamm is utilizing all of his "powers," all of his abilities for a successful result. I highly recommend and endorse Jason D. Lamm to anyone in need of a criminal defense lawyer. To be continued.... Mr. G.

When I first called Jason, he needed to call me back. I gave him my full name, and hung up waiting on his call. When he called back he knew everything about me, and the troubles I was facing. He was meticulous with nailing every fine detail. After a few court hearings, my case was finally dropped. He was worth every penny.

Thank you Jason
Basically I searched out Jason through the internet. My brother got in some serious trouble. He was looking at 60-100 yrs in prison. His bail was set higher than that of someone who commits murder, it was set at $500,000.00. Jason was able to show that was not fair and it was dropped to $10,000.00. We had the sentencing yesterday. Even though my brother was not able to get life probation without prison I feel it was still a decent success. My brother got 5 years instead of 60-100 yrs. So I want to thank Jason for giving my family the opportunity to see him again outside of prison. I would recommend Jason to anyone who has a SERIOUS case. Jason treated my parents with the up most respect. His fees were strict but let me tell you, you get what you pay for!!! Worth every cent.

What an incredible, focused, hands-on attorney - hire this guy.
We just prevailed in an important hearing, all thanks to Jason Lamm. He is so focused, so methodical, so knowledgeable. He really knows what he is doing. We're very experienced with attorneys, and we would recommend Jason's services for any case with a criminal component. He's worth every penny. He cares about his clients. He calls after the hearings, just to check in, the way a good doctor will call after a surgery. Jason gets it - this is your life, and it's as important to him that you prevail in your case as it is to you.

Criminal Defence
Jason Lamm's professional involvement in handling my criminal case and emotional concerns was exemplary. His strategies directed to my criminal defence, case investigations, and the ultimate outcome was excellent. He provided me options and approach methodology, case progress, and yes was at my side each step of the way. My positive experience with Jason and his staff give excellent reason to recommend his legal services to anyone seeking confident assistance in the defence of a criminal act. Hopefully every client will leave the criminal tunnel of fear and anxiety with confidence and assurance that the very best was accomplished. For me, it worked. I recovered from my criminal offence, and am now in the process of recapturing my self-dignity. B.C.

A White Knight in the criminal world.
When trouble comes, take refuge in having Jason D. Lamm Esq in your corner. *if you can get him to say he will take your case* If he does, you can count on a few very important things. Foremost, know that he will be creative, know that he has and will use his savvy and persuasive charm to your best interests. Know that Jason will go the extra mile, he will to keep you up to date about what your options are and how to use them effectively. Jason is a seasoned polished professional , he can navigate the shark infested waters with a absolute certainty and receives the most joy by doing for others. When I was facing trouble, and trouble I had found it let me tell you, Jason swiftly moved into action. He was compassionate and symptomatic, he believed in me and my cause when it seemed like the whole world had turned against me. Jason is a true hero!! Where it took us the better part of 2 years and a full jury trial and some 30+ hearings, Jason methodically chipped away until I was acquitted of all charges! If I had been saddled with a "go through the motions" attorney, who really only saw my case, my outcome would have been much much different. Jason, he got to know me and my case, so much so that he had full recollection of every event every step , his knowledge if these critical and crucial details were the cornerstone of my defense and left no room for error! If you are facing trouble, rest assured that you will find no better anywhere than to have Jason D. Lamm Esq. as your White Night!

Best of the best
Jason represented me twice in reference to the same charge. During the course of my divorce action, my x-wife accused me of domestic violence. Aside from the criminal implications, there were child custody implications. Jason successfully proved that there was no evidence to support the charge and in fact had the arresting police officer supporting my case by the end of the trial. The superior court dropped the restraining order which returned my child visitation as well as succeeding in getting the criminal charges dropped by the judicial court. Jason maintained regular contact throughout the length of the case and always knew the details of my case and personal situation. I have recommended Jason to a friend and would recommend him again without hesitation.

Father of the client
Jason Lamm was recommended to me by an attorney who had previously worked with him. He helped my son with what could have been a serious life changing event. His work "across the aisle" with DA's office provided a favorable outcome. He was available and extremely helpful navigating the legal hurdles.

I regret hiring him over another attorney I interviewed.
I was a person who had no criminal history and was very frightened about what might happen. I found him to be lacking in compassion, or concern for my fears. Trying to get any specifics from him about what he discussed with the prosecution and what he said, or did, to defend me was like trying extract an impacted tooth with a tweezer. He had his assistant send emails which she described as “straight-forward”. They may have been straight-forward for someone with a legal background or with extensive interactions with the court; the information in the emails was NOT straight-forward for someone as frightened as I was. I was made more frightened by the fact that I had no knowledge of what he was doing to defend my interest. He did not address the fact that I was not read my rights by the cop, and he did nothing about the lies that the cop told the grand jury. Trying to arrange a telephone conversation with him, to get some clarification, was like trying to get an audience with the Pope. I paid him a huge amount of money (huge for me) and I felt that he treated me like I didn’t matter; as if I were a low-level pro bono client. If I had known that he had been Censured by Bar in 2003 I would not have selected him. I had a court date that was less than a week away and made a rush decision, in a state of panic. I did not have the presence of mind to check his record with the Bar

Response from Jason Lamm May 16, 2019
This review is most perplexing as it does not align with my recollection of any client whom I have represented. When someone's freedom is on the line, it is understandable that emotions can run high. On the occasions that this occurs, I always encourage my clients to discuss such concerns openly and honestly with me. In my nearly 24 years of practice, this has always seemed to work well, particularly for my clients. The scenario expressed by the reviewer is not one of which I was ever made aware and it most certainly does not address any specific detail that would speak to the facts of the case, let alone the outcome that was achieved. It is unfortunate that all too often, other attorneys, or disingenuous SEO companies working for them, will write bogus reviews in an effort to bring down other attorneys' ratings. I encourage prospective clients to search the internet for the dozens of 5 star reviews that I have rightfully earned. If this review was written by an actual client, I encourage you to contact me directly via email so that I can personally address your concerns.

Relentless to the end, client was not forthcoming
I would give 5 stars but he was not my attorney. Jason was our opposing counsel. He was great, over confident, arrogant and irritating to listen to, starting off strong with defamation of character tactics. Although this may work if the facts were true. However, we would have won no matter who the opposing counsel was. With Jason as the opposing counsel, he made this entertaining and his performance gave the added theatrical touch for a memorable ruling in my favor. I could see his client's thought this was a slam dunk, their confidence was remarkable. Jason can make anyone feel like a winner, but things took a turn once we reciprocated his performance with testimony and verifiable documentation proving the allegations were not factual. It was very obvious Jason didn't like losing and his client should be proud, he didn't lose momentum, he went down with a fight, although it was a not graceful one, slowly that remarkable confidence turned into a child throwing a fit to get his way with threats of appeals before even knowing the ruling! Thank you Jason for taking on a client who had no case, thank you for making them feel like they were going to win. Thank you for making them spend money with no return. Thank you for your amazing performance that helped me win. I couldn't be happier with your services and theatrics. Seeing their faces change from extreme confidence with demeaning smiles to outrage and embarrassment is something I would have never been able to witness without you. I am sure you do not come cheap and every penny your client spent on you was well spent for my entertainment and great story telling. The lesson to be learned here when seeking counsel - believe the negative reviews people! Read all bad reviews on here, on yelp, google etc. Do not hire someone who is willing to disrespect a former paying client or hire someone who refuses to own his losing record to avoid a lower rating.
