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!

MS, RD, LDN

Catherine Perez is a licensed Registered Dietitian with a Master of Science degree in Human Nutrition from Drexel University in Philadelphia, PA. She completed her supervised dietetic practice at the University of Houston in Houston, TX.

Growing up, Catherine did not always have nutrition in mind. In fact, she was fifty pounds overweight and struggling to keep herself away from the same chronic diseases that plagued her family history. After seeing terrifying bloodwork, she made it a personal mission to empower herself with the knowledge needed to avoid a grim future of health. She turned to nutrition. Whole fruits, vegetables, legumes, nuts and seeds became her prescription of choice. It was never a diet. She adopted a completely different lifestyle focused on nutrition, fitness, and wellness of mind. In the process she lost the extra fifty pounds she did not need and regained her health.

In healing herself, Catherine wanted to use her own experiences to help others find their own path of wellness. She received the nutrition education and training necessary to help patients manage and prevent health problems, ranging from heart disease and cancer to type 2 diabetes, high blood pressure, digestive disorders, food allergies and more. She specializes in holistic, sustainable weight loss and weight gain, plant-based nutrition, vegan and vegetarian nutrition, natural and organic eating, and recipe and meal planning development.

Catherine aspires to further her education by becoming Board Certified as a Specialist in Sports Dietetics (CSSD), a personal trainer, and going back to school for a master’s degree in public health. In her spare time, she loves developing new recipes, running, blogging and reading comics.

Following my graduation from Temple, I decided to follow my passion to become a Registered Dietitian.

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!
