At Claggett & Sykes Trial Lawyers, we help injured people throughout Nevada pursue compensation for medical expenses, lost income, and the lasting consequences of serious injuries. With offices in Las Vegas and Reno, our firm represents clients in cases involving motor vehicle crashes, medical malpractice, premises liability, and injuries that occur at casinos and hotels. We understand that every injury claim presents its own circumstances, which is why we focus on developing the evidence and information needed to present each client's case effectively.
People frequently contact our firm after a crash when they need a Las Vegas car accident lawyer because another driver was distracted, impaired, or careless. We also represent those seeking a Las Vegas truck accident lawyer following collisions involving semis, delivery trucks, or other commercial vehicles. Truck accident claims may involve trucking companies, insurance carriers, and federal safety regulations. Our Reno office serves injured people in Northern Nevada with the same approach. We collect evidence, work with experts, and prepare cases for court when a fair settlement is not offered. Consultations are free, and clients may contact either office to discuss their options.

Services
Our personal injury attorneys assist individuals who have experienced harm caused by someone elses negligent actions. We handle cases involving vehicle accidents, traumatic injuries, dangerous products, medical malpractice, nursing home abuse, premises liability, and other personal injury matters. From the beginning of a claim through settlement or trial, our team manages the legal details and works toward a successful outcome. 
We provide experienced legal assistance to individuals and families seriously injured in car accidents. Our attorneys review the circumstances of the collision, available information, medical treatment, and police reports. We explain claim options and serve as your spokesperson with insurance companies. When an agreement cannot be reached, we are prepared to take your case to trial. 
Our legal team provides representation for those injured in semi-truck wrecks resulting from negligent, careless, or reckless practices. The substantial size and weight of commercial trucks can cause devastating damage to smaller vehicles and their occupants. With decades of combined trial experience, we help clients pursue their cases through a contingency fee arrangement and offer free consultations with no fees unless we win. 
Our firm represents people injured in slip and fall accidents and works to hold responsible parties accountable. Because these claims can involve landlords, businesses, renters, and maintenance companies, we apply our knowledge of property safety requirements to each case. Clients pay nothing upfront or by the hour, and our fee comes from an agreed percentage of any settlement or judgment. 
Wrongful death occurs when another persons negligence, recklessness, or unlawful conduct causes a loss of life that reasonable care could have prevented. Surviving relatives may seek financial and non-economic damages connected to that loss. We have successfully handled high-profile wrongful death matters through trial. Our representation allows families to step back from the legal burden during a difficult time. 
Our attorneys understand that motorcycle accidents can have serious consequences for injured riders and their families. Inattentive drivers, dangerous roadway conditions, obstacles, and other motorcycle-related hazards can contribute to crashes, resulting in severe injuries, property loss, and significant medical bills. We help injured motorcyclists pursue claims when another party's negligence caused their accident. 
We help families when a baby is harmed during pregnancy, labor, or delivery. While some complications are sudden and unavoidable, many birth injuries result from medical negligence and could have been prevented. Because these injuries may affect children into their teen and adult years, our attorneys pursue compensation for the resulting losses and provide experienced legal guidance.

Cleggett and Sykes was recommended to me by a friend who is a claim adjuster. She said she tried to think of firms that she feared. They did not disappoint! From gathering information on my accident to setting me up with the proper medical facilities to get me through faster and negotiating with the insurance company to lower my portion of the bills, they were with me every step of the way. My attorney, Mark Willoughby was very thorough. He left no stone unturned and made sure I understood what was happening and I was agreeable with it. I also appreciated Genesis and the rest of the support team for keeping me updated on my case and answering any questions that I had. I received the policy maximum on my case, and I was pleased with the results. I highly recommend it And Sykes!

I did a focus group here to earn some extra money. Brian did a fantastic job presenting the cases.
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!!!!

Being hurt on the job isn't fun under any circumstance and Workman's compensation can be confusing at times. I'm glad that I was able to find a good team like the team at Claggett & Sykes to help me get through the experience. They helped me through the entire process. They made sure I was seen by reputable doctors and took care of the negotiations with the insurance company in charge of my case as well. This was my first experience with Workman's compensation, so it was a relief to have the experience of the legal team at Claggett & Sykes to help guide me through this unfortunate incident. Thank you guys for doing such a great job for me.

Our journey across the states from west to east was a wonderful trip until two days before home, when our truck and travel trailer had an accident on highway 80 in Nevada. We had to search for an attorney in NV to handle the case because we are residents of CA. I didnt know anyone in that state and had to look on the internet. That led me to someone who referred me to Claggett & Sykes. I feel SO fortunate to have found them. My attorney, Christian Augustin and his team were SO kind, compassionate, honest and best of all communicated every step of the journey, never leaving me wondering where I stand. In the end, they got me more money than I anticipated. I highly recommend this firm. They represent the best in service to the client.
