Hi there, I’m Sandy!

Registered Dietitian-Nutrition Therapist & Lifestyle Medicine Practitioner. I’m also a lover of life and anything health, nutrition and fitness-related. It is my mission and passion in life, to help men and women discover what Optimal Health feels like (inside and out). Previous clients and patients refer to me as Their GPS to Better Health, because I simplify ‘changes” as a ROADMAP, a clear guide through nutrition coaching and nutrition therapy to their destination.  When we work together, you will be supported with the tools, a practical and optimistic approach as I help you achieve your goals and develop sustainable habits to live a healthy and balanced life.

No matter your story or history, you can start leading a better life today!

“We only have one body and one mind, taking care of them will not only determine how long we live, rather how well we live.”

My Story


Just so you all know, I didn’t grow up thinking I would be a Dietitian.

Actually, I wanted to be a Doctor- either a Pediatrician or OBGYN – but let me back up a little.

My interest in Nutrition/ Fitness – where it all began. Shortly after moving back from Mexico, where I grew up, I found myself gaining all sorts of weight, went from 100# to 138#  at 5’1. I was chubby, very uncomfortable with myself and had major body issues. It turns out the move back to the U.S. wasn’t merely a change of country but a total change of lifestyle. In Mexico, I was really active and eating healthy foods homemade by my Mom, to having little to no activity and eating ice cream, donuts, and hamburgers. During that time through High School and first years at Diablo Valley College (DVC), I had a love-hate relationship with food. I was so confused that at one point I just figured I am just going to stop eating. Well, that didn’t go very well because I was so hungry but beyond physical hunger, I was really hungry to find a healthy way to lose weight!  I finished my AA and transferred to San Francisco State University with hopes of getting a degree in biochemistry and then going to medical school. At this point my interests were working out, reading food labels and researching nutrition.  I had become a personal trainer and was already helping people make healthy choices and giving them advice.  One day while riding my bike over the Golden Gate Bridge, I had a big AHA moment… I had to go through my own struggle with food and weight to be able to help others!!  I was also obsessed with biology and anatomy and thus was intrigued to perhaps switch my major.

Career Move

As I mentioned earlier, I wanted to become a doctor, but now with my new found loves: Fitness and Nutrition – it felt out of sync to go to school to treat sick people when I wanted to prevent them being sick in the first place!  I wanted to pursue Fitness and Nutrition but I didn’t know where to go. At this point, there was only a handful of “nutritionists” out there. So I researched…it had become my mission and journey in life to learn more about Nutrition on my own but I wondered if there was even a major.  Thankfully I found Registered Dietitian, Kathy Napoli, that provided the guidance I was looking for. I asked her what is the difference between a Nutrition Degree and a Dietetics Degree and made up my mind to immediately change my major to Dietetics!! I have never regretted it!

Why Private Practice

Fast forward a couple of years, when I was working part-time as a personal trainer and part-time as a clinical dietitian. I loved that since I was per diem I was learning EVERY aspect (too many to mention here) of Clinical Nutrition, but I knew I wanted to do more to help people than merely working in a hospital! Hello, that’s why I didn’t want to be a doctor in the first place… so my entrepreneurial spirit started percolating. I pondered opening my own private practice and knew it would be hard as I didn’t have any knowledge of how to run a practice, let alone my OWN business. There weren’t many tools out there but despite the odds, I launched my Private Practice in 2007.
