A person injured because of a distracted, impaired, or careless driver may seek our help as a Las Vegas car accident lawyer.

Through our Reno office, we serve injured individuals in Northern Nevada in the same manner. Our team gathers evidence, consults with experts, and prepares cases for court when a fair settlement is not offered. We provide free consultations at either office so clients can discuss their options with us.

Services
We represent clients who have suffered injuries because of another persons negligence, helping them pursue compensation for physical, emotional, and financial losses. Our attorneys handle personal injury matters involving accidents, unsafe conditions, defective products, medical malpractice, and other forms of negligence. We guide each case through the appropriate legal process, from settlement through trial. 
Our car accident attorneys assist people who have suffered serious injuries in motor vehicle collisions. During your consultation, we discuss the circumstances of the crash, information about the other party, medical treatment, and police reports. We also communicate with insurance companies on your behalf. If negotiations fail to resolve the claim, we are prepared to go to trial. 
We provide legal advocacy for individuals injured in semi-truck collisions. Because large commercial trucks are substantially heavier than passenger vehicles, these crashes can result in severe injuries or fatalities. Our injury trial lawyers bring decades of combined experience to these cases. We offer free consultations and work on a contingency fee basis, charging no fees unless we win. 
Our slip and fall attorneys assist individuals who suffer injuries because property conditions were not reasonably safe. We understand that these incidents may involve landlords, businesses, corporate renters, or maintenance companies. With extensive trial experience, we work to pursue compensation while clients recover. Our contingency fee arrangement requires no upfront payment, and fees are based on an agreed percentage. 
Families may face significant financial and non-economic losses when a loved one dies due to another persons wrongful conduct. These damages can include funeral and burial expenses, medical bills, and lost contributions from the deceased. We offer strategic, experienced representation in wrongful death cases. Our attorneys handle the legal responsibilities while families take needed time to grieve. 
We provide skilled legal assistance to motorcyclists injured in crashes. Motorcycle accidents can result in serious injuries, property loss, and substantial medical expenses, particularly when careless drivers, roadway obstacles, or motorcycle-specific hazards are involved. Our attorneys understand these crashes and pursue claims against negligent drivers and other responsible parties. 
Our birth injury attorneys assist families whose children have suffered harm before or during childbirth. Although unexpected complications can occur, certain injuries arise from preventable medical negligence and may create lasting difficulties and pain. We have a respected record of success, including multiple seven- and eight-figure settlements in birth injury cases, and we help clients pursue compensation for their losses.

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

I had a wonderful experience with Claggett & Sykes . From the day I call I was treated with nothing but respect and concern for myself and my case . Marks compassion and determination got me the absolute best outcome at a more than reasonable rate . I was also assured and assisted by Eunice , Chloe and Karla as they kept me up to date and always ready for the next step . The communication was always consistent and my matters were always solved immediately. I would recommend this law firm and staff to anyone that finds them selves in the same situation as I was in . As I would have been lost without them . And I greatly appreciate everything theyve done for me

My experience with Claggett & Sykes was the best. During the initial meeting, the process was explained clearly and the steps they would take were laid out clearly. They communicated with me very well as the case progressed, and were always available when I had questions or concerns. I was extremely well prepared by them before I was deposed by opposing counsel. They explained the deposition process to me and took me through a live practice session before the actual deposition occurred. Once a settlement offer was received, they were able to negotiate a higher settlement amount. I was extremely pleased with the entire process and the outcome and am very happy I placed my trust in this firm. I highly recommend Claggett & Sykes and especially want to thank Christian Augustin and Brian Blankenship for their excellent and professional handling of my case and achieving an outstanding outcome for me.

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.

I retained Clagett & Sykes to represent me in a personal injury case. My attorney Mark Willoughby and the entire staff were exceptional. They provided me with regular updates on the case and were always available to answer any questions. A Five Star rating is not high enough to describe the level of service and excellent communication.

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.

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.

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.
