I know what it means to change a habit. it is one of the hardest things to do in the whole world! I suffered from asthma, headaches, exhaustion, being overweight and was the kid who got a stomach ache when it was time for gym class! In college, huffing and puffing on a bicycle because I was so out of shape, I said “that’s it! I feel awful and I want to live the rest of my days with energy! I want to live a vital, purposeful life!” And I knew only I could make those changes. I had hit rock bottom.
I sought the support and knowledge to do so, and surrounded myself with as many positive people who were also living deliberately. That meant they were also positive thinkers who helped me emphasize the good and the positive in life, with gratefulness leading the way, every day. My life became more exciting, I shed the weight, became physically fit, beat asthma, and had more energy than I had ever experienced. Filling my head with positivity, staying active, and eating well changed my life forever. I value and embrace every day, yet always work to strike that perfect balance between physical, spiritual and mental health, just like you. I invite you to revel in the support we can provide for you to help you achieve your vital best!

Victoria practices in our Langhorne office
I started my health and wellness career as an Exercise Physiologist. I earned my bachelor’s degree in Exercise and Sports Science from Temple University in 2007. During this time, I worked as an aerobics instructor teaching various fitness classes including step, zumba, weight training, boot camp, water aerobics and Pilates. Following my graduation from Temple, I decided to follow my passion to become a Registered Dietitian. I obtained a second bachelor’s degree from Immaculata University in Nutrition and Dietetics, and became a Registered Dietitian licensed in the state of Pennsylvania. I continued my education earning a Master’s degree in Nutrition Education and am currently pursuing my Master’s degree in Business Administration. I have worked in various healthcare settings including manager of a dialysis center, provider of home health care with a focus on diabetes, hypertension, cardiovascular disease, and cancer. I provided nutrition education in the Philadelphia school district, as well as weight management classes for both adults and kids.
I recently had a baby, and embarked on a weight loss journey because I gained 50 pounds during my pregnancy! But within 10 months, with a structured, mindful eating and exercise plan, I was able to reach my goal weight! I am a firm believer of wholesome, nutritious foods and consistent, moderate exercise. There is no magic pill! It took hard work, dedication, and patience, and I feel better than ever now. I spend my free time at crossfit gyms and I participate in marathons, Spartan races, and ‘tough mudders’ all competitive sports. This is my career, but it is also my passion! I will be a great partner and coach to help you achieve your health and wellness goals!
