“Optimum Seismic was one of many companies I contacted to get a quote for soft story retrofitting on my apartment building. My garage is concrete lined so I was hoping to get an exception instead of having the work done. Everyone I contacted except Optimum told me that I would still have to do the work and quoted an appropriate price. Optimum thought an exception was possible and submitted the request to the city with the supporting documentation. The request was successful and saved me $$$. Dealing with an honest company speaks for itself since you’re at the mercy of all these so-called experts. If you’re looking to deal with an honest knowledgable company who will offer a fair price, then Optimum Seismic would be my choice and should be yours.”

“Optimum Seismic was exceptional in that they took down any shelving or items in the way of their work and when the work was completed they put everything back as it was originally including the paint color. As a landlord, I did not have to supervise. They also kept the job going even when payment was delayed from the HOA. I would highly recommend them. Their fees are competitive or lower than many seismic companies. They were referred to me by a friend who also had an excellent experience with Optimum Seismic.”

“Optimum did an excellent job in retrofitting an apartment building. Optimum truly delivered white glove VIP service through out the entire project. The project was completed in less than 2 months while it was expected to be completed in 5-6 months. The team was very professional, organized, and clean.”

“Optimum did retrofitting work for two of our apartment buildings. They were referred to us by our real estate broker. I could not have been more satisfied with their professionalism, communications, and quality.

They were always available to answer my questions and responded very timely. They explained the requirements for the job and interacted with the City of Los Angeles in our behalf.

I would recommend them and use them again.”

“We just had our four unit building in west Los Angeles retrofitted by Optimum Seismic. Our go to person was Jared Duke. He took us thru the whole project from start to finish answering all questions explaining what was being done.

No surprises with the work to be done as the crew show up on time and completed the job on time. We had no complaints from the tenants as they were kept informed with no surprises.
Thanks Jared and Optimum.

“Our apartment managers, Fertig and Gordon, gave us contact information for Optimum Seismic for help in evaluating our buildingʼs needs for earthquake retrofitting. After speaking to Jared Duke at Optimum, we felt very comfortable in asking them to do the evaluation. They were prompt in completing the engineering appraisal (no retrofit of the building was required) and in filing the required paperwork for the City of Pasadena. It was a long process with the city and Jared was very helpful in expediting everything as much as possible. We were very pleased with their work and their responsiveness to our needs.

“We retained optimum seismic for our earthquake retrofit. This company was so professional from start to finish, they performed the Job miticulous & perfect. My presence as the owner was never required. They even had the best price. I really don’t make recommendations, however in this case, I will & have had many of my friends & relatives use them also.

Property Manager

By Craig L. -

“We are a property management company in business for over 35 years.

We have engaged Optimum Seismic for several of our EQ retrofit projects and they have been an absolute pleasure to work with. Our relationship manager at Optimum Seismic, Jason Pak, is very accessible and responsive and he keeps us up to date on our projects.

One of our projects involved plans prepared by an outside engineering firm which called for a solution which would have caused a major inconvenience to our tenants as they would not have been able to use their parking spaces during the work. Jason contacted me and asked if we would authorize Optimum Seismic to re-engineer a better solution and also at a lower cost!! I could not be happier with their service!
If you are in need or retrofit services, I would highly recommend Optimum Seismic to you and I would especially suggest that you consider having them do your entire project from plans preparation to construction.”

“Optimum seismic was one of my top 3 choices for several reasons. They were very professional and did not ‘bad mouth’ other contractors to earn my business. This was a huge plus for me considering how saturated the market is at the moment. We had the option and flexibility to shop with other contractors once my plans were approved by city.

I ended up doing construction with optimum seismic after seeing their work and their prices were very reasonable considering the quality of work their team delivered. They were on schedule and my price never changed from beginning to finishI would definitely recommend optimum seismic.”

CPM and Chief Executive Officer

By Bruce Harrison, The Beaumont Company -

“I am being proactive with my clients, recommending that they have their retrofits done early to beat the rush and the added expense that will undoubtedly occur once the retrofit deadlines draw near.”


By David Schultz, Schultz Property Management -

“I teamed up with Optimum Seismic to identify properties that may face liabilities when the next major earthquake strikes. I’m a firm believer in proactive management, and the Apartment Management Partnership Program gave us the necessary edge to plan for the future.”

Director & Past President

By Richard Otterstrom, AAGLA -

“After interviewing several companies, I decided to do my earthquake retrofit with Optimum Seismic for my three buildings. Whenever I interview contractors I first look for a company that is ready to give me the best professional outcome at the best price and in that order. That is why I picked Optimum Seismic.”


By Earle Vaughan, AAGLA -

“Optimum Seismic has an impressive track record for professionalism and expertise. They walk you through the entire process and treat your building as if it were their own.”

Executive Director

“Soft story structures have been proven to be unstable in earthquakes, and I want to guard against that for everyone’s benefit.”

“I am extremely happy with the results of the retro-fit of my five unit building by Optimum Seismic. They were very professional and sensitive to my concerns throughout the project. The construction phase of the project took from October 30, 2017 to February 15, 2018. We met and signed the contract with Ali Vahdani (president and CEO). Halis Opcin (assistant project manager) was always available by phone or on-site. Halis was on the project almost every day that work was being performed or inspections were taking place. There were a number of occasions when the project engineer was also on-site and all of the inspections passed timely and at no additional cost.

I was particularly grateful that my tenants were minimally effected since by the end of work each day, the area was cleaned so that they could park normally in the carport overnight. Additionally, when the trenches were open for the foundation work each night they were covered with heavy plywood allowing the tenants to park. When no work was to be performed, we were notified which was beneficial to the tenants since they weren’t required to move their cars by 8:00 am.

I enthusiastically feel that Optimum Seismic surpassed my expectations of a project which could have been a nightmare.”
