Rami Bailony, MD, M.S

Obesity Specialist | California

"The scale is not the problem. The problem is the stigma we as a society place on people with increased weight driven by the misconception that our weight is somehow a representation of our character. We need to move away from judging ourselves by our weight. It’s a number, its reminder, it’s something we track but it does not tell you the whole story.It certainly does not tell you what a marvelous or wonderful person you are. When people ask me what we do at Enara, I often say we help people manage their weight but more importantly we help them see past their weight. "

Dietitian | Danielle Traub, RD, CSOWM

Dietitian | California

"I’ve had to keep a close eye on my weight all of my life and was grateful to turn my passion for food and nutrition into a career. I find obesity fascinating from a scientific perspective, working with patients to reach their health goals personally rewarding, and I couldn’t imagine doing anything else anywhere but Enara."

Rebecca Biscaro, RD

Dietitian | California

"I am so grateful to combine my background in psychology and nutrition to guide my patients to lead balanced and healthy lives. My approach is rooted in concepts of mindful eating, biochemistry, and addressing barriers to change. I love being active with my golden retriever, reading (favorite nutrition-related book is Fat Chance, by Robert Lustig M.D.), and cooking at home. "

Viveca Taylor, MPH, RD

Dietitian | California

"My aim as a provider is to help patients develop a style of eating that they enjoy and that honors their health goals. I love Enara’s “whole food” approach to weight loss because it really encourages people to develop a food routine that is both nutritious and (more importantly) sustainable. As someone with an academic background in public health, much of my degree was oriented around the importance of preventive healthcare, and it’s incredibly rewarding to see that firsthand everyday."
