Services
Our attorneys help injured clients navigate personal injury claims when another party is responsible for their injuries and losses. We represent clients in matters involving transportation accidents, construction accidents, unsafe premises, defective devices, medical negligence, and serious traumatic injuries. By handling the legal process from start to finish, whether through settlement or trial, we work to address the damages caused by negligence. 
We understand that recovering from a serious car accident can be difficult, and we recognize the importance of your claim. Our team meets with you to discuss the collision and available options while reviewing relevant case details, treatment, and police documentation. We represent you before insurance companies and can proceed to trial if necessary. 
Our truck accident attorneys assist people harmed in collisions involving 18-wheelers and semi-trucks. The size and weight of these vehicles can cause catastrophic damage when they strike smaller vehicles. Negligent, careless, or reckless conduct by drivers or trucking companies contributes to many such crashes. We provide experienced legal representation, free consultations, and contingency-based fees with no payment unless we win. 
We represent clients injured in slip and fall accidents and help pursue claims against responsible parties. Our attorneys understand property safety laws and the responsibilities of property owners, landlords, businesses, and maintenance companies. We handle claims on a contingency fee basis, requiring no upfront payment or hourly fees, and pursue settlements or trial representation when necessary. 
We represent families facing the devastating consequences of a wrongful death caused by negligence, recklessness, or an unlawful act. Depending on the circumstances, compensation may address funeral expenses, medical bills, and the deceased persons contributions to beneficiaries. Our attorneys bring substantial trial experience to these matters. We handle the case so families can focus on grieving. 
We understand the challenges associated with motorcycle crashes and the serious harm they can cause. Injured riders may face substantial medical expenses, property losses, and severe injuries after an accident involving a careless driver or other negligent party. Our attorneys provide legal help to motorcyclists and families affected by these collisions. 
Birth injuries can result from trauma occurring during pregnancy, labor, or childbirth, and some may continue to affect a child throughout adolescence and adulthood. We represent families dealing with injuries that may have been prevented through appropriate medical care. Our attorneys have obtained multiple seven- and eight-figure settlements in birth injury cases and assist clients in seeking compensation for their losses. People

I was in legal action with a Bus company in Las Vegas they were refusing claims I was hit by one of their buses on the side walk causing life changing injuries. After years of the accused company dismissing the allegations Claggett and Sykes assisted my original attorneys to bring this cases to a close. The fore said company would not take responsibility for their responsibility of the safety of patrons standing or walking on a public sidewalk.. Claggett and Sykes took control of this egregious in competent act and called them to the public front and their responsibility to protect the public safety of Las Vegas. These Attorneys of Claggett and Sykes Aka Rockstars of legal issues and other attorneys on staff brought this company to the right of their wrongs of this companies bad business practices. I can only say if you need great fantastic service to resolve legal issues to great resolve this is the right legal service to get. They treated us with great respect and compassion and corrected the rights of the wrongs. Thank you for great service and support getting myself and family to this great resolve . They always strive for the best., thank you for all you did.

Claggett & Sykes is the best law firm Ive ever worked with, from the moment I called in to seek legal advice about my car accident (not at fault) Mark was super transparent and informative about my options, fees, and setting up expectations for how my case would unfold. Also shout out to Rory my case manager for always keeping me up to date with the progress of my case, and answering any questions related to my case. They gave me the peace of mind to worry about my day to day life while they did all the hard work and got me compensated greatly. Thank you so much to Mark and Rory for your work

We got to talking. I happened to open up about a struggle I was going through. He asked if it would be OK for the firm to sponsor my son for Christmas! I'm eternally grateful for this law firm and everyone who took the time to help make my son and I have an amazing Christmas!
If I could give 1000 star rating I would!
A special thanks to Brian for being the amazing person putting this all together!

My case was handled with professionalism and follow through the entire process of my lawsuit. I cant rave enough about Brian Blankenship and the excellent job he did for my case. Furthermore, Mark took over the case and did an excellent job as well as Eunice and Karla. They kept me in the loop on every step of the way. Also, I was given updates via email and text messaging. They did an amazing job returning my calls when I left a message. Everyone of the team members had the recent updates on my case and I didnt have to explain myself over and over again. They settled my case in just under 14 months. I received the maximum amount of the claim!! This is the second time Brian Blankenship represented me and received full compensation on my behalf. Thank You Everyone you all ROCK!!!!

I had an amazing experience with Claggett & Sykes Trial Lawyers from start to finish. Mark, my attorney, really took care of everything and made sure I felt confident and informed throughout the entire process. You can tell he genuinely cares and knows his stuff.
Rory, my case manager, was super helpful and always quick to respond. Anytime I had a question or needed an update, he was on it.
Karla handled the disbursement side of things and made everything smooth and stress-free when it came to the settlement. Everything was clear and easy thanks to her.
And Kim, who helped with the property damage, was awesome. She made dealing with the car stuff so much easier and made sure I was treated fairly.
Couldnt have asked for a better team. If you ever need legal help, I definitely recommend Claggett & Sykes.

We want to thank Sean, his whole team of attorneys and office, without them we would never have been able to get through this case. They explained to us the process of our case and even though we had a long case we never felt confused about anything. They were the best representation we could have. We have been fighting our case since 2017, once Claggett and Skyes joined our case they made everything easier for us, we trusted them with everything completely and gave us the justice we have been looking for. Thank you for giving us the justice that Jazmin deserved! We are forever grateful for everyone at Claggett & Sykes!

My husband and I were visiting Vegas last year and unfortunately, our car got rear-ended while we were there. As California residents, we weren't sure who to contact in Nevada for help. A friend of mine recommended Claggett & Sykes to us, and we couldn't be happier with the results. They helped us with a personal injury claim and a diminished value claim for our car. We appreciated that they sent us regular status updates on our case, so we were never left in the dark. We were extremely impressed with their service overall, especially from our Attorney, Christian Augustin. He was friendly, professional and informative. I don't know if this was purposeful, but Christian always seemed to call us with good news on a Friday, which was a nice touch! Thank you, Christian and team, for a great experience.
