Hawaiʻi Pathologist's Laboratory, LLP was the first private pathology group in Hawaiʻi. It was established by Dr. Ann B Catts, Dr. Richard Kelley, and Dr. Drake Will in 1965. Dr. Hideo Namiki joined the group in 1967. Other emeritus partners include Dr. Keith Tonaki and Dr. Thomas Reppun.
The practice initially focused on directing the clinical and pathology laboratories at The Queen's Medical Center. Over time, the scope of the practice widened to include the laboratory directorship and diagnostic pathology needs of patients and medical institutions across the state of Hawaiʻi and around the Pacific basin.
Members of the group also contribute by serving on medical societies, community groups, and volunteer organizations. They continue to teach numerous medical students, residents, and visiting fellows from foreign countries.
