In the medical profession, the body of knowledge has grown so large that it is impossible for any one doctor to remain current in all areas of specialty. Therefore, many hospitals forbid doctors to practice without proof of board certification in their specialty, which provides independent screening of credentials and experience. As a result, patients have added confidence that the doctors who treat their conditions are well qualified and trustworthy.
Similarly, the law has grown so large and complex that attorneys can no longer be all things to all people. In the legal profession, the National Board of Trial Advocacy (NBTA) provides board certification to lawyers who have met their high standards for credentialing and experience, including examinations within area of specialty. Hubert Hamilton is NTBA board certified as a civil trial specialist.
