Practice areas
  1. Securities and investment fraud

    34 years

  2. Consumer protection

    34 years

  3. Insurance
    I represent individual and broker-dealer policyholders in situations where the policyholder's insurance carrier has refused to recognize the need and obligation to defend and indemnify its insured.

I have practiced law in the securities area since 1990 and have successfully handled hundreds of cases involving investors who suffered losses in their brokerage accounts as a result of the mismanagement and fraudulent conduct by brokerage firms and their registered representatives. My efforts have resulted in the recovery of millions of dollars in awards and settlements on behalf of investors who were solicited to invest irreplaceable assets into unsuitable investment products.

Investment loss recovery
Mr. Gonser was able to recover approximately 50% of a large investment loss due to a brokerage firm's inability to appropriately monitor their client's holdings.

Exceptional service! Highly recommend!!
We hired Bob to represent our company in a legal matter with a financial advisor. His communication skills were excellent! He was reasonable yet firm in negotiations. His knowledge and expertise were exceptional. He won our case, which we were certain to lose without his professional expertise. Our family is grateful to him for his dedication to our cause and we consider him our friend.

Excellent Performance
Bob: You should feel proud of your professional performance in handling my mother’s securities arbitration case earlier this year. My family and I extend our personal thanks to you and Marie for your hard work to make our case a success. We were extremely pleased with your performance. G.B., North Carolina

Sued my investment broker
Bob took my case on a contingency basis, which was important to me because I had lost everything in the bad investments my securities broker had recommended. Bob successfully argued in mediation, and got me a sizable reward. I would absolutely recommend Bob, especially for FINRA related cases.

Broker Dealer Dispute
Bob: I just wanted to send you a note now that all this is behind us, to let you know how much we appreciate your effort on our behalf. If it was not for you, we would never have been able to recover anything from our broker/dealer. My sincere thanks for all your help. J.B., California
