Best Personal Injury Lawyer

When my husband and I got in a wreck my grandfather recommended Jarrett to us. When we called Jarrett he made it clear he wasn't going to try going after anyone for all they have, but for what he felt we deserved. Jarrett did just that. He fought the good fight and in the end my husband and I couldn'...t have been more pleased. The communication and clarity throughout the whole process helped ease any stress. I strongly recommend hiring Jarrett. He's not just in it for his own benefit. I felt like he was truly in it for us. My husband and I can't thank him enough for all he's done.

If Iron Man was an attorney

Working with Jarrett has been an exceptional experience. His professionalism, compassion, and commitment to justice are unmatched. He handled my case with both efficiency and empathy, delivering results far faster than I expected while keeping me informed and supported every step of the way. What sta...nds out most is his dedication to helping survivors, particularly those who endured abuse in boarding school environments. His work in that area reflects a level of humanity and courage that goes far beyond legal expertise. He doesn’t just pursue justice, he restores dignity. I’m deeply grateful for his guidance, integrity, and relentless pursuit of what’s right. I would recommend him without hesitation to anyone seeking not only results, but representation rooted in real care and conviction.

My case was on abuse from a religious boarding school.

Jarrett was absolutely amazing! He delt with my case swiftly, and with care and concern for my personal wellbeing. My case was on abuse from a religious boarding school. He helped me win compensation far more than I expected. I would highly recommend him, and I would also hire him again in the future... if needed!

Want your prayers answered = Call Jarrett “now”!

Jarrett went out on leap and represented my injured 14 yr old daughter. From the beginning, he treated the incident as if she was his daughter that was impacted/injured. Jarrett is a very kind and knowledgeable professional - he kept it REAL and transparent with any/everything going on with the case.... We had a stall in the case; however, he didn’t give up and made it happen. After receiving 3 “no’s”, I found Jarrett on Google; Jarrett was truly a “GOD SENT ANGEL”! **PSA - Steer far away from those “BIG TIME” billboard law firms - give Jarrett a call “NOW”!**

Not all heroes wear capes

As a stay at home mom my job is to take care of my family. I am the sole driver in our family due to medical conditions and when I was rear ended a while ago our lives were turned upside down. Medical visits, life altering changes, pain, suffering and not being able to spend time with my family becam...e my new life. After trying to deal with the insurance myself (to be honest lawyers scared me) I knew I needed help. When Jerrett got ahold of my case I was barely hanging on to any hope. I kept saying as long as I walked away without medical bills or any other debt we would be ok because let's face it a single income family isn't easy but more debt could ruin it. Today I got the final numbers for my wreck and as I'm typing this out I'm sobbing. Jerrett and his team have changed our lives, while I'll never be able to get rid of the physical pain the emotions of gratitude are beyond compare. If you are struggling to find someone who will listen to you or treat you like you are a person please give Jerrett a call. He listened, was my voice and took everything to heart. I will forever be thankful for him and his amazing team! If I could give more stars I would!!! Thank you from the bottom of my heart Jerrett and team! Thank you for helping my family and changing our lives!!!
