Medicine Built for How You Live

Meet the Schmidts.

We are a husband-wife team of physicians. Yes, we talk shop at dinner and yes that's how FXN Medical Group started. Well, it really started when we met in medical school at Loma Linda. That's where Nick was first introduced to volleyball when he saw Xian playing at the local sand court. Fortunately, Xian saw Nick as a charity case and pulled him off the bench. That's all it took. When Xian took a job in San Diego, Nick chased her to the coast, and we've been building a little family by the beach ever since.

Why FXN? Well it's the initials of our family and it's also shorthand for function, the two things we care about most.

The practice

Why we built FXN Medical Group

Modern medicine is good at adding years. It is less good at making sure those years feel like yours: hiking, lifting your grandkids, paddling out on a Saturday morning. We brought our two specialties together under one roof so that your care team looks after both how long and how well you live.

Small by design

Fewer patients means unhurried visits, a doctor who knows you, and an answer when you call. Many practices carry large patient panels and short appointments. We intentionally cap our membership, so visits are unhurried and we get to know you personally. The practice panel is capped at 150.

Old-fashioned care, modern tools

We're your neighbors, not a system. We take the time to know you and care about you the way medicine used to work. Our goal is to restore the traditional doctor-patient relationship while adding modern tools. Medicine is changing fast, and we're genuinely excited about the future. Technologies are opening new doors in pattern recognition, predictive medicine and new treatment possibilities. We want our patients to benefit as that work matures. Tools support our judgment. They never replace it.

Off the clock

Off the clock, we're raising our son, playing beach volleyball, and getting out on the water to surf and fish. We love being part of the San Diego community, and we try to practice what we preach.
