A different angle on a problem
that hasn't been solved yet
Early in his training, Dr. Na noticed a recurring problem: classical Eastern medicine texts were routinely mistranslated into English — not out of carelessness, but because the gap between Eastern and Western medical thinking runs genuinely deep. Closing that gap without dumbing anything down became the starting point for how he practices today.
Dr. Na founded Greenleaf Clinic in 2007. Over nearly two decades and more than 7,000 patients, he has treated conditions ranging from chronic pain and anxiety to digestive disorders, skin conditions, fertility challenges, and post-cancer treatment recovery — including infertility he faced personally, which deepened both his research and his understanding of patients navigating that path.
Most patients arriving at Greenleaf have already been through the Western medical system — tests, specialists, medications. They're not looking for someone to dismiss what they've been through. They're looking for a different angle on a problem that hasn't been solved yet. That's what this practice offers.
His approach is direct. He asks a lot of questions, explains what he observes, and sets realistic expectations. He doesn't recommend more treatments than are necessary.
