About Sarah

Sarah Mirkin,
RDN, CPT

I'm Sarah Mirkin, RDN, a registered dietitian specializing in irritable bowel syndrome (IBS), small intestinal bacterial overgrowth (SIBO), and weight management.

I provide personalized, evidence-based nutrition guidance to help you find relief from digestive symptoms, achieve sustainable weight results, and feel confident in your body.

With over 25 years of experience, I guide individuals who are ready to stop guessing. For weight management, my approach focuses on practical guidance and sustainable habit change — no diets, no rigid rules. For digestive concerns like IBS and SIBO, I provide clear, structured protocols to identify root causes and resolve symptoms.

My approach is practical, strategic, and tailored to your unique physiology, lifestyle, and goals — so you can achieve measurable, lasting progress.

My certification as a personal trainer allows me to strategically integrate movement to support your overall progress.

My Story

My
Story

In my early years, I experienced firsthand how restrictive dieting and extreme exercise can disrupt both metabolism and digestive health.

"After struggling with weight fluctuations and eventually developing digestive issues, I began studying IBS and SIBO extensively. What I learned transformed not only my own health — but the way I practice nutrition."

I understand how frustrating it can feel to be told your labs are "normal" while symptoms persist. I also understand how exhausting it is to follow plan after plan without lasting results.

Through a root-cause, evidence-based approach, I was able to restore balance and rebuild digestive health. That experience shaped my commitment to helping others do the same.

Sarah trained at the University of Vermont and completed her dietetic internship at UC Berkeley. Prior to founding Kitchen Coach in 2007, she worked as the dietitian for Cedars-Sinai Medical Group and Health Associates. She is a Monash University Certified Low-FODMAP Dietitian and sees clients in Beverly Hills, Palm Beach, and virtually nationwide.
