your health and happiness is all that matters


My curiosity with obesity began in 1989, after seeing how others were being judged and stereotyped based ont their weight.  I was furious because I knew that these same old, mindless stereotypes were and had always been far from the truth.  Those labeled “fat and lazy” were among the hardest working, loyal, dependable, and giving people I knew.  I didn’t get how anyone could mkae, let alone vocalize, such ignorant judgments with nothing more to go on than pants size. 

In 2000, I decided to become a registered dietitian to help people lose weight. I began my major in dietetics at San Diego State University.  

After my first professor turned out to be morbidly obese, and my second professor was borderline anorexic, wearing a winter coat in the middel of summer, I quickly realized there was a lot more to the obesity epidemic than just understanding nutrition. 

Between the years 2000 – 2002, I found myself gaining close to forty pounds!  How was that even possible? I was studying everything about nutrition, and I was a personal trainer and spinning (indoor cycling) instructor, yet I had become overweight. 

What had happened? I had started working for the first time in my life, my finances were a mess, I wanted to be independent and on my own, and I had lost my sense of purpose – my life was a complete mess.  I just wasn’t taking care of myself and it showed. 

Can you relate? 

While, yes, at the end of the day, losing weight is so easy – just burn more calories than you consume, duh – it’s real life and the day-to-day pressure we put on ourselves that causes us to get stuck – overweight, anxious, and sick.  And that’s where my passion comes in!

I’ve made it my life’s mission to end obesity by empowering you to live a healthy, happy and balanced life. I hope you will join me on this journey.
