Biographical Information

Mark Davis has been recognized as one of the best trial lawyers in Hawaii and in the United States. Mr. Davis, a graduate of Tulane University and Washington University School of Law, has focused his law practice over the last thirty years representing injured victims in cases involving serious personal injury and medical malpractice. He has achieved record verdicts and settlements in Hawaii for numerous cases over the course of his career.

Mr. Davis has been recognized as preeminent in his practice by his fellow attorneys in both the plaintiffs and defense bar. He is listed in The Best Lawyers in America and was elected to membership by his peers in The American College of Trial Lawyers, The International Academy of Trial Lawyers, The International Society of Barristers, and The American Board of Trial Advocates.

Mr. Davis has been extremely active in civil rights litigation throughout the State of Hawaii. He was on The National Board of Directors of the ACLU and was one of Hawaii’s most active civil rights lawyers serving as lead counsel in numerous first amendment, discrimination, and equal rights cases. Mr. Davis’ practice frequently included representation of the “little guy,” the victim, the disenfranchised, and the prisoner. He successfully had city and state laws struck down by federal courts that prohibited unconventional religious activities disproportionate treatment for non-residents, women, and minorities. He tried the first Title VII employment discrimination case ever brought to trial in the Hawaii Federal Court. In recent years, he has lectured and written on the subject of trial advocacy and is an Adjunct Professor at the University of Hawaii Law School.
