Recommendation

Mr. LeBoff from Klein & Wilson is a brilliant attorney who works very hard for his clients. He is informed, honest and a very compassionate individual. Mr. LeBoff always made sure I understood every aspect of my case, from the possible outcomes to the overall process. From the very beginning Mr. LeBoff kept me informed of options to take as well as the possible consequences thereof. His knowledge reaches far and is very diverse to say the least; there was never a turn that he did not anticipate. Mr. LeBoff always answered all my questions knowledgeably and he always answered phone calls and emails immediately. Mr. LeBoff brought my lawsuit to a very satisfying end and he was a blessing to my case.

4.5 out of 5 stars

Michael LeBoff and Brian Kelly represented myself and my company in an attempted business ownership claim. They gave solid guidance on what I was up against. We ended up in a jury trial that Michael LeBoff litigated to a unanimous verdict in our favor. K&W did a fantastic job.
