Kelly Gunn

Lifestyle Guide

Kelly Gunn is a cancer survivor, certified personal trainer, published writer, and founder of Feinix Haus — described as Peloton meets Soho House for post-cancer women.

When Kelly's treatment ended, the world handed her a finish line and expected her to resume. She didn't. A year after her double mastectomy she competed in two bodybuilding competitions. She rebuilt her body, started another company, and got published in three national magazines. She is taking Europe solo this year. She is leading a retreat in Belize in December 2026.

Not despite cancer. Because of who she became after it.
Feinix Haus is the lifestyle wellness and fitness membership community Kelly built because it didn't exist. A tiered ecosystem — The Clubhaus, The Studio, The Inner Circle, and The Private Study — designed to meet post-cancer women exactly where they are and walk alongside them as they build a life that actually fits.

There are 4 million breast cancer survivors in the United States. When treatment ends, most of them become invisible to the wellness and fitness industries. Feinix Haus sees them. Not as survivors in recovery. As women in their After — living fully, moving intentionally, and building the lives they almost didn't get to live.

Kelly's work has been featured in Wildfire Magazine, C-Heads Magazine, and on National Cancer Survivors Day. She appears on the Moments That Changed You podcast and is a frequent voice on post-cancer identity, body reclamation, and the lifestyle of the After.
