Helpful beyond expectation and informative
I had the privilege of consulting with Jeff Sonn and he was very knowledgable on my investment issue and how to approach it. Jeff took time to help me, going well above what I had anticipated or even hoped for. Jeff communicated well and was clear and concise with his assistance. He provided links to relevant information and described the steps I need to take.

If your are fortunate enough
If you are fortunate enough to be represented by this Law Firm then you are truly fortunate enough. By chance I contacted the firm about representing me in a suit against a Broker. Jeff reached out for me personally said he felt I had a good case and he assigned Adolfo to the case. Cannot say enough good things about Adolfo, he listened, communicated often, encouraged me to have my facts in line, etc. He was always professional, courteous and on top of all things. My outcome was better than I thought it would be but that was due to the Sonn Law Firm and only them.

Jeff is a winner.......
Jeff is plain and simple, THE BEST. He helped recover money from a ponzi scheme that seemed impossible to us. He thinks outside the box and is tenacious. And he answers his calls and emails promptly. Many thanks, Jeff and staff...............Judy in Prescott, Az

Prompt, Upstanding, Intelligent
Can't thank Jeff enough! I called Jeff, slighty upset and frantic, in search of information that I was unable to find anywhere else. As TD Ameritrade was withholding 35k in funds. Within 2 rings Jeff picked up the phone. He patiently listened to my long drawn out BS and then calmly provided the exact advice I had been searching for all day(for free). Much appreciated and highly recommended. If I ever have any future issues this will be the first person I will contact.

Fantastic Recovery!
Our family was the victim of a devastating scam and theft scheme from a crooked financial advisor. After a prominent securities law firm said "No" to the prospect of recovering the money that was stolen, Jeff Sonn said, "Yes". He and his associate masterfully and enthusiastically handled our complicated securities case and achieved a fantastic recovery for us that went well beyond our expectations.

Jeffrey did an excellent job of explaining directly what to do
Jeffrey took time out of his day to get specifically to the issue at hand. The situation I had was complicated, but his questions clarified exactly what needed to happen. Good questions are the heart of any good litigation and with his questions, I was to get good advice and direction to next steps in my situation. Most helpful and would recommend him highly.

Above and beyond
Mr. Sonn went above and beyond when I consulted with him concerning my mother's securities losses. He is very knowledgeable and was patient when explaining the process of arbitration and our best avenues for resolution. He was also very prompt to call and was very accessible.

Puerto Rico Bonds
Jeff Sonn, our attorney did a wonderful work representing us against a powerful bank investment institution that invested all our savings in Puerto Rico debt without disclosing to us the high risk level of the concentrated investment strategy. Based on the strong evidence of negligence and fraud of our bank institution presented by Jeff Sonn our bank institution accepted, the day before going to FINRA arbitration, to settle the case and to pay us a compensatory award for the damages and financial losses suffered due to their breach of contract and fraudulent activities. Without hesitation I would recommend Jeff Sonn to represent any claimant confronted with a similar case.
