Before, she sat on the sidelines.

Now she’s running, hiking, jumping rope, and keeping up with her kids 💪

That’s the goal. Not perfection. Participation.

Weight loss surgery is a tool. When you use it the right way and commit to change, your life opens up in ways you didn’t think were possible.

Proud of this patient for doing exactly that.

Two surgeons. One mission: helping patients reclaim their health.

Dr. Feiz and Dr. Rim are combining expertise in weight loss surgery, reflux care, and advanced gastrointestinal treatment to give patients a healthier future.

Heartburn isn’t just uncomfortable, it can leave a footprint.

When stomach acid repeatedly travels into the esophagus, it can cause changes to the lining over time because that tissue isn’t designed to handle acid. That’s why, during an endoscopy, we carefully look for signs of irritation or cellular changes.

If you’re dealing with frequent heartburn or reflux, it’s important not to ignore it. The good news is that reflux is very treatable, especially when it’s evaluated early.

This is what commitment looks like. 💪✨

A powerful transformation built on courage, consistency, and the right surgical tool at the right time. And when patients show up for themselves, the results can be life-changing.

Proud of this patient for choosing health, strength, and a brand-new chapter.

Sorry for all the ads you might get, but I would be happy to see you!

Shopping in New York with her 18-year-old daughter. Wearing whatever she wants. Saying yes without hesitation. That’s the freedom she gained after weight loss surgery.

Helping patients move from doubt to confidence, from sitting out to fully showing up, is why I do this. And I’m honored she trusted me with her journey!

This transformation isn’t just about the number on the scale, it’s about reclaiming health, confidence, and energy. With...
