Diamond Head Mortuary & Williams Funeral Services

Established 1859


Diamond Head Mortuary in partnership with Williams Funeral Services has  been proudly providing funeral services on Oahu for generations.  Diamond Head Mortuary carries on the tradition that started with the establishment of Williams Funeral Services in 1859, making it the oldest funeral service provider in Hawaii. We take pride in being able to guide people through some of their most difficult days and in maintaining a setting that allows people to find solace. Celebrating life is our mission. That’s never changed. And with pride, it never will.

Located near the famous Diamond Head Crater, our mortuary offers the families we serve a comfortable and relaxing setting at the time of their greatest need. Our beautiful, stained glass Chapel can accommodate approximately 280 people with additional room available in our lanai. With ample on-site parking and our convenient location in the vicinity of Waikiki, Diamond Head Mortuary is the perfect place to show respect for your loved ones.
