I dreamed of being a teacher since I was a little girl in China. Spending 20 plus years in school, I earned my doctorate in Comparative Literature from Rutgers University in 2007 and started my college professor career right after that. Living the dream, I taught passionately until the arrival of my second child in Jan. 2013, when commuting conflicted severely with raising a family with my husband. Deciding to resign from my job was a life-changing turning point. It was at that time that I discovered group fitness and the fact that I could continue to live the dream of teaching in that classroom as well. 
In May of 2013 I obtained my very first certification in Les Mills BodyCombat, to be followed soon after by BodyPump, and then BodyAttack, CXWORX, BodyFlow, and many more over the years. Meanwhile I also dove into various avenues of rounding out my fitness expertise by attending workshops and modules to continually work on my skill sets both as a physical role model and a teacher. I am certified as a personal trainer through the National Academy of Sports Medicine, with a specialty on Fitness Nutrition. 
The more I learn, the more I am inspired to learn, and the more I am humbled by the amount of information I don’t know. Learning drives and feeds my teaching. Learning cannot stop, because teaching has been, is, and will always be my dream. 
Living the dream, I founded Body Revolution LLC in June, 2018, with endless encouragement and support from my husband and dear friends. The dream is to bring what I love and know to as many people as I can, building a community of people who love to move, know how to move well, and always want to move more. Body Revolution is a resolution to challenge, commit, and change oneself for the better. Come join me for your Body Revolution!

I took the leap from client to trainer in 2014 and became a certified Les Mills BodyPump instructor. I fell in love with instructing and continued my certifications in Pound & TRX. 

I have always had a deep passion and connection to movement, music, fitness and feeling strong. I love pushing out of my comfort zone and trying new things and found the energy and connection in group fitness contagious and so inspiring. I wanted to share my enthusiasm and spread the love and learn how to lead others on their own fitness path and reach their goals…actually surpass their goals! 

Some of the most rewarding moments I have had as an instructor is seeing a client’s progress and hearing them say that they feel stronger & more confident because of training together. We bridge the gap between not only understanding fitness and also the mechanics of our bodies but also safe training and how the two together create amazing changes and improvements for our health. But more than just improving our physical health, training together positively impacts our emotional wellness, which is just as important. To know that I am part of this personal growth for clients can hold such a positive impact in my life and I am honored to be part of their journey. I can’t wait to hit the studio with you and have a fantastic time working hard and breaking a sweat, all with a smile!

Dietitian Nutritionist Consultant


My philosophy is simple:

Balance, not perfection, is the key to a healthy & happy lifestyle.

We work together to create innovative and sustainable solutions that work for YOU and YOUR GOALS!

I truly have a passion for all things healthy!  As a Nutritionist, I help my clients break the ‘diet cycle’ and rebuild a harmonious relationship with food.  As a fitness enthusiast and certified Les Mills Fitness Instructor, I view exercise as an integral part of my life and my family’s.  Helping my clients find the joy in activity is often a fundamental part of our program.  As an Arbonne Independent Consultant, I have the opportunity to offer superior nutrition products.

I graduated Summa Cum Laude from Rutgers University with a B.S. in Nutritional Sciences /Dietetics.  I completed my dietetic internship with Sodexo and have obtained an Interdisciplinary Board Certification in Obesity & Weight Management through the Commission on Dietetic Registration and the Academy of Nutrition and Dietetics.  I also have a B.S. in Finance from The College of New Jersey and spent 10 years working in New York and London for some of the world’s top investment banks.  My diverse background gives me a unique perspective on the diverse circumstances of my clients.

I am the mother of 3 beautiful girls, including a set of twins.  They keep me running, and often a little crazed, but I wouldn’t want it any other way!  Feeding an active family of 5, has given me hands-on experience in finding creative solutions for healthy eating at all ages.
