Why is Koran so successful in medical malpractice and personal injury cases? We have more than 100 years of experience and focus mainly on medical malpractice. We take time to review all potential cases by ourselves and then send them to medical professionals. This allows you to accurately evaluate the opinions of the medical professionals and better understand each case. We also have weekly meetings and work with the team to discuss new cases. This collaboration allows you to share the knowledge and experience of each attorney.





This company is as good as possible.  I had little experience using a law firm.  This company took up my case when other companies did not, kept in touch with me on a daily and easy basis, always knew where my case was, knew the facts better than anyone else, and was very, very compassionate in all respects.  My injury was real, but it was difficult to prove.  Sometimes, as I was said to be common to all cases, there were difficulties threatening our cases, but this company was constantly showing a strong attitude toward me.  They are not only experienced in the kind of law they practice, but also simply smart...And really kind people.  My son was also a lawyer, always telling me his impressions of my case.  David Cholera is a gentleman and very talented as a lawyer...I strongly recommend him and his entire company to those who need lawyers who specialize in this kind of law.  I am happy that I found them.
