Aloha. I'm Jim Zittnan, the owner of Koalition Grillz, LLC. I started my business with a vision.

After a 5 year incarceration, I was determined to stay positive, be a law abiding citizen and contribute to my community. Grillz were always something that I had interest in and learning how to make them became my passion. Through my dedication and commitment to learn, I became the first and only grillz jeweler whose work can be branded as Made In Hawai’i. I put this touch and individuality into each grill that we personally deliver to our customers, whom we prefer to see as family and friends.

We understand that cosmetic grillz can be so much more than just a fashion statement, and we love the joy and confidence we can help provide by giving our customers one more reason to smile even bigger. Mahalo!!

In addition to the 1st, 2nd and 3rd place winners from the formal judging, banquet attendees vote for their favorite entries as "People's Choice" award winners in each category.

This year (2022), the design contest will be held in October. The deadline to submit entries is Wednesday, October 12th. Entries needed to be delivered to Tom Wheeler at Opal Fields (International Market Place, Waikiki - by the Tesla dealership) with entry forms and payment submitted prior to delivery.
