Mr. Tomassian's firm represented our group of homeowners in a very complex landslide case. The other side wanted to settle for peanuts. Mr. Tomassian made sure that did not happen. Many of the homes were red tagged and will have to be torn down. Thanks to Mr. Tomassian, we were made whole again. Highly recommend! Thank you Mr. Tomassian for all of your hard work.

Serge Tomassian and his firm have represented me for several years and I have found that he and the other lawyers in the firm to be ethical, hard working, knowledgeable and result orientated... I have used Mr Tomassian for Real Estate, Business Contract and Personal Injury matters in both Orange County and the Inland Empire. I have been very happy with the results that he was able to get and how fair the firm's fees were for their services compared to other firms that I had previously used.

Hiring Serge Tomassian was the best decision I ever made. After a dishonest contractor left my grandma’s home unsafe and incomplete, and a previous attorney dragged our case out for years with no results, I was exhausted and ready to give up. From day one, Serge was ethical, transparent, and aggressive when needed. He clearly explained the strategy, kept me updated, and his team (Brenda & Karen) always responded with compassion. Most importantly, he delivered results, settling our case for the maximum amount possible in record time. Thanks to Serge, my grandma and I are finally back in our home. He fought hard for us, treated us with integrity, and restored our peace of mind. If you need the best construction defect or real estate attorney in Orange County, call Serge Tomassian. I cannot recommend him enough.

My experience with Tomassian, Inouye, & Grigorian LLP was exceptional. From the moment my wife first spoke with Serge Tomassian, we knew we were in good hands. Serge Tomassian and Talin Grigorian expertise in construction law proved invaluable as they navigated our complex cases with precision and dedication. As a family, we made the decision to trust them, and it was truly the best choice we could have made. They tackled challenging civil cases involving construction contractor licensing, extortion, Real Estate agent/Broker fees, and a troublesome contract with a large Title company. Despite the many layers to these cases and the formidable opponents we faced, Serge and Talin guided and educated us every step of the way, ultimately leading us to victory. Their meticulous preparation and deep understanding of every detail ensured that we were well-prepared for trial. Throughout the weeks-long trial, they continued to support and advocate for us. Their commitment to re

My wife and I experienced significant damage to our home due to movement of the slope behind our home. We met with Mr. Tomassian to discuss our situation and if we could recover damages from our HOA who was responsible for maintaining the slope. Mr. Tomassian successfully led us through the legal process resulting in a settlement we were very much pleased with. We highly recommend anyone with a similar problem to contact Mr. Tomassian for advice on how to proceed.

I've hired Serge and Michael as my Lawyer to handle my contraction defects case for my resident in Orange County. I've lost 300K for my addition project of my new housel because of lack of profession and defects from my previous contractor. Serge and Michael help me fired this contractor and get all my money back!!! Since the contractor has no asset nor money and his insurance is not response for most of my loss. Serge and Michael use their professional acknowledge to find any possibility to help me recover my loss. After one and a half year we win the case!!! Highly recommend them for any construction case. They know what they are good at, during the arbitration, I almost give up, because they really don't have anything to give. But Serge found a way to make it happen, he had the insurance company pay me the max money they can get. I'm so glad I can get my money back, happy customer! 我聘请了Serge和Michael作为我的律师来为我在奥兰治县新屋处理我的装修不合格案。由于缺乏专业性和以前承包商工作的缺陷,我新房的扩建项目损失了30万美元。我们最终拿回损失!
