One person referring friends and family, that says volumes. I have patients where I do refractive surgery, then it's their sister, their uncle, their, yeah it's friends and family that they send and refer to our office. You can sit there and listen to all the commercials in the world, but if you know somebody personally that has a personal experience with the practice that carries a lot more weight. And we do, we get a lot of referrals from patients. Patients have a good outcome, and they're referring patients because they're like oh no, I told them you don't need to go anywhere else. You just go to Griffin & Reed. And I hear that often from the patients that get referred. It's less like how'd you hear about us. You know I've done husband and wives, brothers, you know, sisters, moms, and dads. And so moms and dads referring their kids here. And it's the way we've structured our whole practice is to have that type of atmosphere.
