Client Reviews
"Alexander is my attorney who has been thorough, aggressive, focused, and a credit to the legal profession. Five months ago Alex was thrown into my case due to a tragedy by my previous lawyer. He was given few records, learned the circumstances, and devoted his attention so that this week he stood before a judge to try my case. Well done Alexander!" Allan Zwirn
"Alex is an outstanding lawyer well knowledgeable and very professional I do not usually recommend lawyers to family members or friends but I definitely would recommend Alex thanks for a great job well done." Winston, R.
