Every doctor I'd seen spent 8 minutes with me. Dr. Liu spent an hour. She found what three MRIs missed — with a handheld probe in the office.

I finally understand what's happening in my body. Dr. Liu explained everything on the ultrasound screen in real time. No other doctor has ever done that.

I came in with a running injury and left with a complete plan — nutrition, sleep, training smarter. This is the care I didn't know I needed.

Finally, a doctor who doesn't just tell me to rest. We fixed the problem and I'm stronger than before. I wish I'd found this practice sooner.
