Ryan H Gerrits

Born outside of Detroit, MI I worked in various

Fields throughout my life.  After completing college at

The Citadel, The Military College of South Carolina, I moved to beautiful Kailua-Kona.  Since being on island have worked very hard to learn the ways of the island and the Hawaiian culture.  I have multiple years experience in business and make it a point to treat every individual with care and respect. Raising my daughter Kau'ionalani Gerrits has brought a whole new perspective to my life, and that is, ohana takes priority over all.  I hope to enlarge my hanai family to all I do business with.


Here at Hanai Brothers Plumbing, LLC we wish to provide the western side of the Big Island of Hawaii the best, most effective plumbing work possible.

It is our mission to treat the residents of this island with 100% priority.  The co-founders, Eric Triphahn and Ryan Gerrits live here in Kona, and will do everything in their power to make sure that you are satisfied.

Living on Hawaii Island is a blessing to all of us.  Hanai Brothers intends to show every person the same aloha and care in order to make sure that everyone's needs are being met.


Hanai Brothers has the experience and professionalism needed for you to feel comfortable letting us into your home.   Remember, we are not strangers, but your newly found Hanai family. 

Mahalo Nui Loa for the consideration to assist with your needs.

Eric R Triphahn

Born in Texas, raised in Phoenix Arizona.  I started plumbing at 18 working with my family.  I received my city of Phoenix journeyman plumbing and gas fitter license when I was 25.  Over the years I have come to love what I do.  I made my way to Hawaii 3 years ago and have been doing service/emergency repairs as well as new construction since my arrival.  I was fortunate enough to marry my best friend, the most beautiful Hawaiian I have ever known.  We recently had a gorgeous baby girl together which added another member to my ohana, including my daughter from a previous marriage.  I have reached a point in my life where I am ready to branch out as a business owner and help as many people as possible.

In the time that I have known Ryan (about 3 1/2 years) and Eric (about a year) they have shown clearly that the customer comes first.  The professionalism they display is exactly the kind of people that I enjoy associating with.  Can't thank you guys enough for what you do, and will be calling you with any issues I may have in the future.
