Well, we refer to Oral Surgery Hawaii mostly our implant and wisdom teeth extraction cases. A good thing about the referral process is when our patients come back from Oral Surgery Hawaii, they're blown away by just the professionalism and, of course, the expertise that Dr. Yamamoto and Dr. Kitamura have. I think one of the other reasons why we enjoy the referrals to Oral Surgery Hawaii is because our patients feel comfortable when they come here, from the greeting to the whole process. It makes it easier for us, and they feel comfortable just as much as when they come to our practice, so it's a good referral source for us.
