I could be redundant and repeat all that I have listed above but to be brief, I will summarize by saying that Mr. Castaner deserves a "10" because he is a genuinely nice person, who is very bright, energetic, diligent, honest, trustworthy, scholarly, well spoken, and in the midst of turmoil and adversity somehow manages to have fun in the process. If I needed a lawyer in Puerto Rico, I would not hesitate to hire Alberto Castaner.

A must lawyer in PR Astute, fast and diligent, Mr. Castaner is the partner you need to represent you in Puerto Rico. From your initial contact, he will guide you through all the necessary steps to secure the best outcome the law can deliver. A must in PR just when you need him the most.

I can not say how grateful I am, for this guy! I highly recommend attorney Castañer to anyone looking for a personal injury lawyer in Puerto Rico. I talked to four other attorneys before him, and they all told me I had no chance of recovering from the establishment where I suffered a serious accident. Not only did Castañer take my case, but he was able to settle it for a lot more than we had anticipated. He always kept me appraised of the status and progress of my case and was very kind and understanding.

Q. I fell in Puerto Rico broke my toe. I live in the state of New York Joe do I four a lawsuit for my injuries and pain
A: Thanks for your question. The answer is: it depends. If you fell and broke your toe because of someone else's negligent acts or omissions (e.g. a restaurant who left a wet floor unattended without "Caution" signs or a store who had a step that does not meet construction codes) then you may be entitled to compensation. However, if you fell because you tripped on your own feet, then you would not. Feel free to give us a call so we can get more details about your accident and see if it is something we can help you with.

Best Regards,

Alberto Casañer
