Dr. Keron Magness, MD
Founder, Magnarosa Health | Board-Certified Emergency Medicine Physician 

Welcome to Magnarosa Health, dedicated to helping patients find their way to wellness.

Hi, I’m Dr. Keron Magness.  I spent over 20 years treating emergencies in some of California’s busiest hospitals, helping patients through some of life’s most critical moments. Over time, I realized that the best way to make a difference wasn’t just treating crises — it was helping people prevent them.  After years of watching patients cycle through temporary fixes — only to return sicker and more frustrated — I knew there had to be a better way.  Driven by my lifelong passion for wellness, athletics, and nutrition, I shifted my focus to what truly matters: uncovering deeper causes, not just masking symptoms. Today, I help people reclaim their energy, balance their hormones, and optimize their health as they age — so they can feel strong, clear, and confident in their bodies again.

I earned my medical degree with honors from the University of Texas Medical School and completed my residency in Emergency Medicine at UCLA. Working through the global pandemic in a high-acuity, inner-city ER, I witnessed how profoundly a person’s baseline health influences their ability to recover. That experience, along with my own health journey, reshaped my perspective and ultimately led me to functional medicine — an integrative model that combines the strengths of conventional medicine with personalized investigation and treatment strategies. I’ve since completed advanced coursework with the Institute for Functional Medicine and the Kalish Institute, focusing on gut health, women’s hormones, mitochondrial energetics, and immune health.

Outside of my medical practice, I live in Southern California with my husband and three children. A former NCAA Division I swimmer, I still find joy in movement — whether it’s beach volleyball with my girlfriends, skiing with my kids, or long walks in the hills with our bernedoodle. Movement, meditation, and family time keep me grounded.

Testimonials

Some feedback from our clients

I had been struggling with fatigue and digestive issues for years, and traditional doctors couldn’t pinpoint the cause. After working with Dr. Magness, I finally have more energy, better digestion, and feel balanced for the first time in a long time. Highly recommended!

I finally feel like myself again.

I was exhausted, foggy, and my blood sugars kept climbing no matter what I did. Dr. Magness took the time to really understand what was going on and gave me a plan that finally made sense. My energy is back, my labs are improving, and I feel in control of my health again.

She gave me hope and a plan.
