I couldn't be more pleased with my experience with Cooper Elliott. From day one, Sean Alto and his team were not only professional and knowledgeable but also incredibly compassionate. They truly understood what I was going through and made sure I felt supported every step of the way. Their patience, empathy, and dedication made the entire legal process easy and stress-free, so I could focus on my recovery. Thanks to their hard work, I received the compensation I needed to move forward with my life. I highly recommend Cooper Elliott to anyone seeking a personal injury lawyer.
I cannot recommend Cooper Elliot enough.
I was involved in a serious car accident after just having welcoming our new son into the world.
When you are at your lowest, you remember with great detail how people treat you. Sean and his team treated me and my family with nothing but compassion, grace and care.
The stress, anxiety, and fear were only mitigated by the EXTRAORDINARY passion, care, and speed this firm operates at.
A huge thank you to Sean Alto with his incredible professionalism. I never once felt that Sean and the team at Cooper Elliot had anything other than my best interest.
Thank you Cooper Elliot for being a light during a very challenging time.

I just closed out a case with Bart Keyes, and it was a long, but very good experience. Kim Cecil was fantastic in getting me the things that I needed to do so we could present a strong case. This was my first time ever doing something like this, and Bart's guidance was flawless. He kept me calm during the mediation process and answered all of my questions. We were on the same page, and he represented everything I needed. I would HIGHLY recommend Bart and this firm to anyone who needs representation! Thank you Bart and Kim!
I recently had the pleasure of speaking to (Sean Alto) the Cooper-Elliott law firm and although they could not take my case they directed me to other lawyers that would be more in the wheelhouse of our case. They called me back in a timely manner and were very nice to counsel me about the facts in our case and absolutely truthful, kind and caring with me. I would definitely recommend this law firm to others. Thankful, Terri Taylor
Cooper Elliott is a top notch law firm that settled my daughter’s accident. The first time we met in person, Sean Alto came to meet us in my daughter’s hospital room. He has a warm demeanor, and a nice conversational tone. Throughout our discussion and setting expectations, we knew we could trust him. His approach is kind and thoughtful and he has a lot of previous experience that aided to understanding the steps our case would take. It took approximately 6 months to settle our case. We worked closely with Michael Tonovitz for catch-ups and questions. He and Kimberly Burroughs helped a great deal with explanations, patience and humanity. I couldn’t recommend a better law firm for any case more than Cooper Elliott.
I can’t thank this legal team enough for the way they handled my case. From start to finish, they were compassionate, understanding, and truly knowledgeable in navigating such a sensitive and difficult matter. Their guidance gave me strength, and their dedication ensured a just outcome. They helped me achieve exactly what I was hoping for—justice, closure, and a sense of resolution. I’m deeply grateful for their support and expertise.
Unfortunately I am a seasoned client with many lawyers. Lawyers that were unethical, uncaring, lazy and unknowledgeable about my circumstances. Finally I found a lawyer with an exceptional law firm who is not only professional and knowledgeable but his ethics and dedication to my case was immeasurable. Sean Alto, with Cooper Elliott Law Firm represented me in malpractice case against another attorney. Although I didn't get to see my original case through I was able to recover the damages with Sean. This was possible because I was represented by a one of a kind lawyer who treats his clients and his work load personally as though it is " his case". Cooper Elliott is a top law firm and they make sure that as the client you are well informed, well taken care of and treated respectfully. Thank you for everything Sean Alto
I was in an accident last June. I was overwhelmed with everything I had to deal with after my accident, along with recovering. I needed legal help, so I eventually was referred to Kaela King. Her compassion, knowledge, and professionalism is what makes her the best at what she does. While going through my case she helped me advocate not only for myself but my wellbeing, and my physical health. I can’t thank Kaela and Sophie enough for all that they did to help me through a very difficult time. If you’re wondering if you should use Cooper and Elliot, you absolutely should they are amazing at walking you through the steps and helping any way that they can!
Kaela was incredible. She helped me navigate through I world I know nothing about and did it with grace, patience and love. She asked good questions, and gave sound wisdom while all the while making me feel like the most important thing in the world. I am extremely grateful for her help and assistance. No one every wants to be in a situation where they need legal help but Kaela's attention to detail, persistence, patience, and wisdom made her simply the best thing for my family and I at the time. I would highly recommend her services for any number of reason and qualifications.
Rex Elliott at Cooper Elliott is truly exceptional. He was the perfect balance of empathy and toughness—understanding my issue deeply while giving me unwavering confidence throughout the entire process. One of the things I appreciated most was how easy he was to reach and communicate with, always making me feel heard and supported. Thanks to his expertise, we had a resolution within just three days and received everything we asked for. I couldn’t have asked for a better advocate. Rex is simply the best! Highly recommend!
I spoke on the phone with a young lady name Tammy, an absolute angel. She was there for me emotionally through the phone after my financial crisis and she allowed me to vent and she was very supportive and understanding to me. She led me in the direction on the right ladies for my current situation and I am very thankful to have crossed paths with her. She had a sense of humor that brought my mood from down to back up and trusting faith we will get thru this. Thank you again for the motivation Tammy.
I worked with Rex and Adam along with multiple others. The team was extremely knowledgeable and transparent through my entire case to help me best understand my options. I felt supported during a very difficult time and was confident in the advice I received.

For the most part when you need legal representation something has not gone well. You are concerned, anxiety is up, you feel low, even frightened, and there does not seem to be a light anywhere around. Thus, I am very happy that I called CooperElliott. Much of that despair began to lift, I knew I had someone behind me, in front of me, beside me, and that I was not alone. I was treated like I had been a client for forever by everyone I was in contact with and met with. A great firm that will fight for you, and that means a great deal when you need someone who will do that with you. Thank you CooperElliott.
Ben good lawyer, he schedule a zoom to hear my case. Could not help me, but he answer every question i had. Help me what i need to do next, i was very helpfull. Recommended. Type of lawyer that is no looking fo the money, he really wanted to help.
I highly recommend Kaela King. She provided efficient and effective legal consultation over the phone and via email. Her communications were clear, timely, and respectful.

Even though Mr. Cooper wasn’t able to take my case, he was kind enough to point me in the right direction and answer all my questions, regarding my matter. I appreciate your time!
Through the law firm Cooper Elliott, I dealt with attorney, Bart Keyes. Bart was very thorough and understood that I Had no clue of how this process would go. Bart took the time needed to help educate me on this process for a very positive outcome.
I can’t thank Bart and the staff at Cooper Elliott enough for all they have done for me. I am now able to move on with my life!

My name is Anthony Johnson and I just spoke with Ben Cooper about a wrongful accusation case, unfortunately they don't take on cases such as these but Ben gave me some valuable information and I could tell he really was trying to help me. Very knowledgeable and a great listener. Give him all call for anything law related. Made me feel important.
I worked with Adam Richards and his team. They were empathetic to my situation and extremely professional. I don't know what I would have done without their expert guidance and counsel. Adam really knows his stuff, and it was clear he had an excellent rapport with all who assisted in the case. Adam's communication abilities were next level. I never had to worry about getting ahold of him when needed. I know he and his team will continue to knock it out of the park for all future clients like they did for me.
My husband, Bob and I were injured in an automobile accident in December, 2022 when someone came through a Stop sign. We contacted Cooper Elliott, and were fortunate to work with Sean Alto and Kaela King. They came to our home several times to meet us and discuss the case, and got to know us personally as well as professionally. They really care about their clients! In addition, Michael Tonovitz stayed in contact with us to keep us informed on the progress of the case, which was resolved to our satisfaction.
We highly recommend this law firm for personal injury!

Highly Recommend Jon with Cooper & Elliott firm. He was very responsive and went above and beyond to help with our situation. Can't thank him enough for everything he has done for us. He will be our "Guy" moving forward for any legal help!!
Excellent firm i am so glad I found cooper Elliot. My attorneys Jon and Adam helped me through the entire process
I am so glad I found cooper Elliot. My attorneys Jon and Adam helped me through the entire process. After a traumatic experience in my life I was confused and in pain. They worked tirelessly to become familiar with all the details of my story and represented me in a way that made me more able to process and understand the trauma myself. This was huge for me, while there’s still healing to do, I can do that work now instead of staying in a purgatory of cognitive dissonance. They didn’t just win justice for me, they are a significant part of my healing journey. They were validating, non judgmental, honest, and knowledgeable.
Excellent firm. The firm was referred to us for a commercial dispute. Bart Keyes is a master negotiator and kept us informed at all times. Highly recommend.
Jonathan Bond handled a personal injury claim for me quickly with maximum results. He’s pleasant and enjoyable to work with, as well as compassionate. The firm handled all the legwork of getting medical records and copies of paperwork, which not all firms do. I would recommend Jonathan to anyone and would definitely go back to him if the need were to arise again.
Very satisfied! We dealt with Bart Keyes who showed genuine interest in our situation. Bart was always very quick to respond when we had questions and kept us informed throughout the case. If you need legal representation for a commercial real estate dispute we highly recommend Bart and the Cooper Elliot firm!
I honestly struggle to find the words to describe how incredible this firm is, especially Jeffrey Kenny and Sean Alto. 7 years ago, my family started a journey through a nightmare. When the criminal justice system fell woefully short, Jeff agreed to take on our incredibly challenging and lengthy case, with no other reason than that it was the right thing to do, and he believed we deserved justice. There were so many times when I would have understood if they walked away, but they refused and vowed to get us the justice we deserved, and almost 7 years later, they have given my family just that. I will never, ever, forget what they have done for us. We were never just another case. They made us feel like we were their ONLY case! Thank you will never come close to the gratitude and respect I have for Jeff and Sean, as well as for Cooper Elliott. They will be superheroes in our home, forever!
Everyone from top to bottom in this company is always polite and ready to help. and no matter what is thrown their way, it's handled quickly and skillfully. Whoever represents you will show themselves to be a master in their craft. You can feel safe working with Cooper Elliott.
I would highly recommend Cooper Elliott to any of my friends and family! Chip Cooper was extremely helpful guiding me through a difficult process. Chip was patient with me and provided feedback during the process that kept me informed until the desired outcome was achieved. There were interactions with other staff of the firm (whose names I do not know) that were helpful as well, I was impressed with the entire team!
Adam Richards is the best attorney I have ever met. He is responsive and very patient (I had a lot of questions) and he truly cares. He fought hard for me and he stands up to the bully. he is not afraid to take on anyone. Anytime I hear someone who has a legal issue I go out of my way to recommend Adam. He is unlike any attorney I have ever met. He is compassionate and he always answers his phone. There is no way I would have got the results I received with any other attorney. He was a bulldog in my case and really went to bat for me. Words cant express how grateful I am to him. His actions personally affected my life in a very positive way. He protected me in so many ways I couldn't begin to name them. It is a great feeling when you know your attorney outmatches the other party's attorney and it is obvious.
