Inland Empire Personal Injury Lawyer with National-Caliber Trial Experience

Jonathan L. King is a personal injury trial attorney at The Law Offices of Justin H. King in Rancho Cucamonga, California. He represents seriously injured individuals and their families across the Inland Empire and Southern California, including Rancho Cucamonga, Fontana, San Bernardino, Riverside, Ontario, Upland, Rialto, and Victorville.

Mr. King has been recognized by Best Lawyers in America® in both 2025 and 2026 for Personal Injury Litigation – Plaintiffs, named to the National Association of Distinguished Counsel as among the top one percent of attorneys nationwide, and rated 10.0 (the highest possible) by Avvo. He has litigated to verdict 17 jury trials and more than 40 bench trials and has handled hundreds of matters across three jurisdictions.

Appointed Class Counsel, 2026. Mr. King and his brother Justin H. King were appointed class counsel in a certified statewide class action against National General Insurance Company on behalf of California policyholders.

Catastrophic Injury, Wrongful Death, and Trucking Practice

Mr. King concentrates his practice in cases involving life-altering injuries and the deaths of family members. His core caseload includes car and motor vehicle collisions, truck and commercial vehicle crashes, wrongful death, traumatic brain injury (TBI), and premises liability matters throughout San Bernardino County, Riverside County, and Los Angeles County.

He also handles government tort claims under California’s Government Claims Act — matters that require strict adherence to procedural deadlines that many private attorneys are not equipped to manage — and medical malpractice cases.

Class Action and Insurance Bad Faith Litigation

Mr. King is among a small number of Inland Empire personal injury attorneys with active class action experience. In 2026, he and his brother Justin H. King were appointed class counsel in a certified statewide class action against National General Insurance Company. Class certification under California Code of Civil Procedure section 382 requires the court to find numerosity, commonality, typicality, and adequacy of representation — a demanding procedural threshold that establishes the case may proceed on behalf of all affected California policyholders.

His broader practice includes individual insurance bad faith claims and complex coverage litigation against major carriers.

Trial Experience and Background

Mr. King is a native of Rancho Cucamonga. His father, the Honorable Jeffrey King, served as a Justice of the California Fourth District Court of Appeal for thirteen years following his service as a San Bernardino County Superior Court Judge. His mother, the Honorable Pamela Preston King, served as a San Bernardino County Superior Court Judge after a career that included work as Deputy District Attorney, civil litigator, and Deputy Public Defender. His brothers, Justin H. King and Oliver P. King, are his law partners at the firm; all three have been recognized by Best Lawyers in America® in 2025 and 2026.

Mr. King began his career with summer associate positions at Skadden, Arps, Slate, Meagher & Flom and Deutsche Bank, and joined Gibson, Dunn & Crutcher in New York as an associate following law school. He left commercial practice to represent individuals, accepting a position as a public defender with the Committee for Public Counsel Services in Massachusetts and later with the Office of the Appellate Defender and the Office of the State Public Defender in Helena, Montana, where he tried felony and misdemeanor cases and argued criminal appeals before the Montana Supreme Court.

Mr. King founded his own personal injury practice, Jonathan King PLLC, in Helena in 2016. He later joined Doubek, Pyfer & Storrar, one of Montana’s most established plaintiff personal injury firms, where he litigated personal injury and civil rights matters in Montana district courts. He also served as a court-appointed mediator for Lewis and Clark County District Court in matters involving the Department of Child and Family Services.

Mr. King returned to Rancho Cucamonga in late 2021 and joined The Law Offices of Justin H. King in 2022.

I was in a car accident on the 15 freeway near Rancho Cucamonga and had no idea where to turn. A family member referred me to The Law Offices of Justin H. King and it was the best decision I made. Justin handled everything personally from insurance calls, medical liens, all of it. He never made me feel like just another case. We settled for far more than I expected. If you're in the Inland Empire and need someone who actually knows how to fight for you, this is the firm.

After my car accident on the I-15 in Fontana, I was dealing with injuries, a totaled car, and an insurance company that kept stalling. The Law Offices of Justin H. King took my case and immediately made me feel like I had real advocates on my side. Jonathan King was incredibly thorough and kept me updated throughout the whole process. We ended up with a much better outcome than I thought possible. If you need a car accident lawyer in Fontana, don't wait. Call them first.

There’s so many things I can say about Justin, Garrett and the team. Of course having to get an attorney is stressful enough as it is.
When I called, I was welcomed with the utmost kindness! They listened to my story and never once made me feel unheard of unimportant! Justin, himself, responded so quickly to every call, text or concern. And Garrett, omg, very thorough, very sweet, very funny. The fact that I can relax and laugh was a great sign that I was in the right place. I’m grateful for the fight that they fought for me!
Hopefully I won’t be back, but if I need ANYTHING, I know they’re just a call/text away.
Thank you so incredibly much for literally everything!

I can’t say enough good things about Justin King Law. My attorneys, Oliver and Garrett, took incredible care of me and handled my case with empathy and professionalism. After being rear-ended, I was unable to pick up my children, and the situation felt overwhelming. They not only connected me with the right health professionals and care, but when the other insurance provider denied my claim, they fought hard—and secured even more than we originally asked for.

Garrett especially took the time to thoroughly explain the process to both me and my husband, making sure we always felt informed and confident. Thanks to them, I never had to worry. I was able to focus on my family and career while they handled everything. Within just six months, my case was closed, and Oliver personally greeted me in the office to walk me through the settlement.

I am truly grateful for their dedication and would recommend Justin King Law, a small family owned practice.

I hired J King Law to represent me when I was hit by a car walking into a grocery store in Hesperia, Ca. When I explained the situation to Justin and his firm they were extremely understanding and reassuring that this will be taken care of and they will fight for me. Throughout the process the whole team was very attentive and honest about everything that came up. I have nothing but, great things to say about this law firm. I highly recommend them to anyone that has suffered any injury whether it’s major or minor. The thing I appreciated most were the updates given almost every 2 weeks. They broke everything down to help me understand it all and I’m just so grateful for them. Thank you so much J King Law!

The team at Law Office of Justin King went above and beyond with my case.
It was my first big automobile accident while being 6 months pregnant and I was terrified. I called them the same day and they took on my case immediately.
Throughout the whole process they were communicative and on top of everything. I would recommend to everyone and would go back to them again if need be.
Thank you to this amazingly firm !

Wow! I can't say enough good things about the Law Offices of Justin King. Attitude starts at the top, & this firm is top tier. They represented me (& yes we won!) for an injury I sustained while riding my motorcycle westbound on the 10. Someone changed lanes without looking, which resulted in a knee injury, a lot of physical therapy, & a totaled motorcycle. I wasn't sure what to do or if this were even something worth pursuing. I found Justin's webpage & sent a quick message to him on a Saturday night then thought nothing of it. My first call from Justin was Sunday morning. I was immediately impressed. After hearing a bit of my story & asking a few questions I was ready to have Justin represent me. My first question was "How much do I need to come up with to get this started? Justin replied, you don't owe anything until we win. Not unless, until. That set the tone of the next 2 years of my life. As your case progresses it'll require work from you & a whole team working to represent you. Staci will call & let you know she's emailing documents that require signatures; Garrett will call to ask for details they need to understand & yes, he will call to remind you that you forgot to sign a document 3 days earlier. These are great people who genuinely care. They will take time to understand your needs & they communicate every step of the way. If you are injured, you need to call Justin & his team right away. You will not be disappointed!

Google only allows 5 stars, but these guys deserve 10!

I was involved in my first big automobile accident last year, in Yorba Linda. I was a bit overwhelmed as you can imagine. Friends suggested that I hire an attorney to handle my case and I was not quite sure how to proceed. I was very fortunate when I was referred to Justin King’s office.

I met with Mr. King and found him to be very personable and he listened to my concerns. I felt very comfortable and confident that he would help me in getting a fair outcome to my case.

I want to also thank Garrett Tuckerman for all he did in keeping me updated with everything going on with my case and for being there whenever I had any questions or concerns. I also want to mention Leoni Barrera who was always pleasant and supportive when I called.

I highly recommend The Law Offices of Justin H. King for your personal injury needs. I feel that Mr. King and his whole staff, with their knowledge, expertise and professionalism will help make your experience a less stressful one.

Last July I was struck by a falling case of liquor at Total Wine in Rancho Cucamonga which led to a slip and fall. My friends and family urged me to contact a lawyer after discovering I needed surgery to repair my broken wrist. A friend found Justin King on Google. Justin was compassionate, accessible, and took charge from the very first meeting. He was able to obtain the surveillance video capturing the entire incident, and made an appointment for me to see a prominent neurologist after the video showed the case struck the front of my head. The entire staff at The Law Offices of Justin H. King were very easy to work with, and I always felt like my case was getting personal attention. Thank you Garrett, Staci, and Leoni! My case went to mediation and settled for more than 3x what they originally offered. If you have been injured in an accident, I highly recommend The Law Offices of Justin H. King.

I want to thank Justin and his amazing office. They made a very traumatic/ nightmare of a situation into a more bearable situation every step of the way. They kept us updated and we were reassured that we were in good hands. I want to also express my gratitude to Garrett for being so empathic and supportive through the ups and downs that comes with a case. We are so blessed to have had them handle our case. I would recommend them to anyone who is looking for a professional and dependable office. Thank you again Justin King Office!!!

I went from feeling like a basket case from all the stress to feeling calm and collected after talking to Justin. He is a phenomenal personal injury lawyer and is a truly calming and reassuring presence. This firm helped me in ways I can't even adequately put into words, other than to say Thank You, Justin, to you and your awesome team.

After an auto accident, I felt really nervous calling an attorney because I had never worked with one before. But from the first conversation I had with Jessica, I felt so at ease. Justin then called me and was so easy going and we had a nice conversation too. The entire staff took great care of me and I am very happy.

I was in a car accident that was not my fault two years ago. A friend of mine had a family member who had been helped in the past by Justin King, and they suggested I call him. I'm so glad I did! Justin and his team took great care of my situation and got a great settlement for me. I highly recommend them if you have been in an accident. You will be very happy with what this firm. They are smart, hard-working, honest, and take great care of their clients.

When I needed a lawyer following a car accident on the Interstate 15 Freeway in Rancho Cucamonga, Justin King, and his team were there for me. I appreciated how his entire staff always seemed happy to answer my questions and were so good about returning all my phone calls and emails. I could tell this firm has immense experience in helping people get their life back after an unfortunate car crash. I was so happy with the outcome of my case and the results Justin obtained from the insurance company on my behalf. I have recommended their office to all my family members and neighbors. I hope you never need to call them. But if you need the best car accident lawyers, I can vouch that they are excellent.
