Outstanding lawyers with a big heart are a cut above mere good ones. Attorney Leon J. Frommer is not only exemplary in the legal arena, he is worthy of trust because he gets the job done expediently balanced with compassion. When my car got totaled in a MVA two years ago, I sought his assistance based on glowing recommendations from a church family. I praise God for designating him to be my advocate, counselor, and representative in a battle I am clueless to begin with. He diligently tackled my personal injury case and fought strategically to get a settlement up to the maximum policy limit despite the hurdles of a raging global pandemic. With Mr. Frommer on the frontline, the maze of uncertainties seemed less perplexing. With most days overwhelmed with pain, he showed me empathy that made a world of difference in the pain relief management steps he directed me to pursue. He gently guided me to get back on track whenever I lost vision of our purpose and goal even if he sounded like a “broken record.” The exceptional professionalism he manifested by breaking the big legal jargon chunks into smaller pieces made this tedious and lengthy process clearer and manageable. At various points of wanting to give up, he relentlessly followed through and his tenacity was more than uplifting each time as his words of wisdom were comforting enough to help me regain hope and confidence. Above all, the peace of mind with Mr. Frommer and his kind assistant, Leny, in my legal team is priceless. For a job well done, Team Frommer deserves a shoutout of gratitude and cheers of appreciation. Thank you for being an instrument of blessings. Yay and to God be all the glory! Maraming salamat po, Law Offices of Leon J Frommer!

Having Frommer Law by my side during the recovery of my rear ended car accident in 2019 was one of the best decisions made… Mr. Frommer worked so hard to get the settlement I deserved. He’s very caring, professional and most importantly does everything that needs to get done while you focus on your recovery. He gave me a peace of mind. I truly appreciate his dedication, commitment and determination. Thank you very much Leon.

Many Blessings to you and Leny…

First, I want to say I rarely write reviews for anything but I felt compelled to write a review to acknowledge Leon Frommer and his entire legal team for the wonderful job they did to assist us in securing Naturalized US Citizenship for my wife.

We were at least 15 years overdue in filing due to unexpected life events and being busy working adults. We were nervous and unclear if we would have a favorable outcome due to the amount of time that had passed but Leon and his team, including Art Cardenas, assured us that everything would go smoothly and that we should be able to pass the interview with no issues once that time comes. In August 2019, we finally decided to submit the application under the thorough and careful guidance of the Frommer Law team.

Several months had passed. We finally got the first of several notifications to appear for fingerprinting. We thought the interview would soon follow but unfortunately the pandemic started and slowed the application process down. However, once again, Leon and his team assured us that everything would be just fine. Several months had passed by. We finally got the notice to appear for the interview with the US Immigration and Naturalization Department in Los Angeles in October 2020.

The interview was a total success. Leon, Art Cardenas and the Frommer Law Team carefully guided us along the way, step by step. We truly feel that a successful outcome would not have been possible without the expert legal advice and compassion they demonstrated. The Frommer Law Team did a FANTASTIC job! I highly recommend them for your immigration and various other legal needs. We want to express our deep appreciation and thank you for such a wonderful job! THANK YOU!

Attorney Leon Frommer was the Attorney I chose to represent me in my San Juan Capistrano sidewalk trip and fall injury, accident case.

Mr. Frommer has a calming demeanor, taking on the pressure that would normally be the clients. Mr. Frommer instantly puts you at ease when called to his office to gather information needed for him to fight on your behalf. He is easy to talk to, is patient and diligent in tediously gathering information from many sources. He made me feel at ease during the entire process, helping me get compensation for the pain and suffering I experienced.

Mr. Frommer’s years of experience, and knowledge gave me a secure feeling. He gave advice that was always in my best interest.

Leon Frommer is companionate, honest, and polite. And was never impatient with me when I didn’t understand the legal terminology. He was kind enough to explain everything until I understood it, as we moved forward in my case.

I feel that my Attorney, Leon Frommer, did an exceptional job on my trip and fall, injury, accident case. It was because of his hard work, and knowledge that I was awarded more than I thought I would have gotten.

His secretary, Lenny, is also an asset to Mr. Frommer’s firm. She’s very efficient and was quick to gather information for my case when asked.

He would be my first choice if I ever need an attorney to fight for me again. I am very satisfied with the outcome of my case, thanks to my Attorney, Leon Frommer!

Frommer had given me the best legal advise for my situation with the goal of getting my car repaired and most importantly to help attain healing from my injuries by availing every possible treatments and therapies.

-Leny Antigua

“I had a car accident three years ago, and at the time I was very weary of pursuing my case since it was the third in a period of 4 years. It was not an easy case and the insurance company low balled my settlement and offered a very low amount. Leon did not give up and through his perseverance and hard work, my case settled for the policy limit, three years later. At the time I was also working as his assistant so I am well aware of the time and dedication he puts into his work. I would like to mention too, how he was very supportive of me when I had to leave his office to pursue my education and dream career. Thank you Leon for guiding me through this and helping me through to what could have been a difficult three years ! Special thanks to his new assistant, Leny, for your hard work.”

Thank you for everything Leon. Not only for all the time and hours you gave over the past 4yrs, but mostly for just being you!”

-Shelle Greene

“When I was involved in my car accident, I was nervous to take action, get treatment, and deal with the other party. It was honestly a bit overwhelming. I was referred by a friend to work with Leon Frommer and I’m soo glad I did! Once he took on my case, I did not have to deal with the other party at all. I only dealt with Leon, and his very kind and helpful assistant Lenny. He is very detailed and thorough. If I had any questions or concerns he himself would be so gracious to speak with me. It’s nice to be able to speak directly to the one who will be fighting for you. He is very friendly, warm, and incredibly helpful. I feel like he got to know me, how I live, and really truly understood how the accident affected me and my family. This was the first time I ever worked with a lawyer and Mr. Frommer made everything smooth, easy, and stress free. I would not hesitate to call him for anything else that I may need. Thank you for everything Leon!”

“The Law Offices of Leon J. Frommer helped me immensely in attaining my student visa (F-1 visa). My case was quite complicated. It began when I travelled to the US with a tourist visa (B1/B2 visa) and, while on vacation, I decided to stay and further my studies. My status was successfully changed in the US from tourist to student. A year later, I went home to visit family for the holidays. Since I needed to get a student visa, I applied for one at the US Consulate in Manila to return to the US; however, I was denied. My supposedly two-week visit in Manila turned into five months. The Law Offices of Leon J. Frommer was tremendously helpful in processing my student visa and preparing me for my second interview. They were very hands on with my case, looked into every detail and worked with accuracy. With their knowledge, time and efforts, I was successfully granted my student visa on my second interview. I am now back in the US continuing my studies.”


“Enough can’t be said about Leon. I was involved in a serious head on collision that was not my fault and sustained injuries to my lower back that eventually resulted in surgery. I was being completely ignored by the other driver’s insurance company when I rejected their nuisance value settlement offer. Then, I retained Leon and he got me the other driver’s entire policy which took care of my medical bills and compensated me for my pain and suffering. Leon was professional, handled my case aggressively, always responded to my correspondence and always returned my phone calls in a timely manner. I highly recommend his law firm.”

-Xavier T.

“I was very happy with the work Attorney Leon Frommer did for me after my car accident in 2010. With his help, I was able to get another car, medical treatments, and monetary compensation.

I was able to get a check from the other insurance company in a timely manner, to help me get another car, since my car was totalled.

He also assisted in helping me get medical treatments (orthopedics, physical therapy and chiropractics) for my injuries…1) Right Knee- Torn Meniscus, 2) Headaches, and 3) Stiffness to my Neck and Back.

Mr. Frommer was diligent in working with the other party’s insurance company- in my monetary compensation for pain and suffering, and medical bills.

In addition to all the work he’s done, he has helped me a great deal in alleviating the stress and worries that comes with this type of situation.

I am very grateful for all he’s done for me. Thanks Leon!”
