Ghassemian Law Group Celebrates the Grand Opening of Its Larger Headquarters in Mission Viejo, California

Recently Ghassemian Law Group was proud to announce the opening of a new office in Irvine as our firm has grown. In May, our celebration continued on the first of the month when we invited our professional colleagues, family, and friends to the grand opening of our newly expanded head office in Mission Viejo. That open house event, which welcomed a crowd of 150 to mingle in our refreshed, larger space, provided us the opportunity to share our excitement with the very people who have been such a large part of our success. We deeply appreciate the support of everyone who was able to join us, as well as for those who could not be present but who are nevertheless part of our journey to this new chapter for our firm.

What’s next for Ghassemian Law Group? As one of the fastest growing litigation law firms in construction, real estate, and business law providing premier service to our clients in Southern California, our focus remains on the winning formula that sets us apart: small firm attention combined with big-firm expertise.

Putting Our Experience to Work for You

No venture, whether a business or an investment, is without risk. The thought that what seemed like a promising venture could turn into a nightmare of litigation, however, can make every new opportunity feel like it may be full of unknown threats that could put your personal and professional assets in danger. Worse, the path to asserting your rights in a business dispute or defending yourself from a lawsuit can often feel like it is full of unpleasant choices.

Do you hire a big firm for the perceived depth of expertise, accepting that you will pay steep hourly rates for impersonal service but hoping it is worth it to get the job done? If you have not quite reached the point where a lawsuit has been filed, do you worry that hiring a lawyer at all will ignite a brewing disagreement to an expensive legal battle?

Our decades of collective experience have given us an unmatched savvy in resolving business disputes as cost-effectively as possible. We understand that when your business is on the line, you need a legal team you can trust to have your long-term interests in mind. For countless scores of clients, we have been that team, and our growth allows us to provide that peace of mind for even more.
