Our Practice

The idea of Ohana Direct Primary Care (DPC) was born during a family vacation in Kauai; hence the name "Ohana", which means "Family" in Hawaiian.  It was at this time that we were brainstorming on how to bring medical care to the homes of patients in a affordable, safe, and beneficial manner. At Ohana DPC, we value the concept of family. Our business is family owned by Jessica and Cassandra's families. Ohana was founded on the principle that as a community, we take care of each other, just as we would our own families. Ohana offers you and your family a very personal, compassionate, quick, and stress free medical care experience. 


At Ohana, we follow a medical practice model called "Direct Primary Care". Direct primary care is a model in which patients pay their primary care provider directly, rather than through their insurance company. In practice, that means patients pay a monthly fee giving them access to their provider instead of paying a insurance company premiums and co-pays.  With Direct Primary Care, you will have access to your provider via their personal cell phone. By eliminating the middle man (insurance companies), direct primary care practices can focus their attention on what is most important, the patient. You will never wait weeks to get in to see your provider, all your visits will have at least a hour time block reserved, and if your sick or injured we will see you at a same or next day appointment time! Too sick to come to the office? That's okay, we can come to you!

At Ohana, we also offer whole sale discount pricing on lab work, medications, and imaging studies. Yes, that means we pass all our savings right back to you! If you have traditional medical coverage, we can also have your insurance billed for all labs, diagnostics, and medications if you decide not to get the discounts through us! 

Don't have a membership with us? That's okay, we will still see you for same day/next day urgent care visits according to our urgent care pricing. 

We look forward to meeting you and all your healthcare goals!
