I'm also a functional medicine trained practitioner & offer nutritional, hormone & digestive testing when needed.
I am a Registered Dietitian with experience treating hormone imbalances, inflammation and gut/digestive issues that manifest in conditions such as PCOS, pre diabetes, insulin resistance, weight gain, bloating and IBS. Clients often come to me seeking not only the treatment for their symptoms, but to identify the root causes as to why they have those symptoms in the first place. I help my patients regain a sense of confidence in their body and eating patterns. I work with patients with goals to lose weight, improve their fertility/hormone balance, restore digestive health & regain a sense of energy as well as brain function & memory.

Diagnosed with PCOS? Struggling with digestive issues, period problems, thyroid problems, or fertility challenges? Experiencing symptoms of fatigue, low energy, bloating, acne, and/ or hair loss? If you’re finding it difficult to get answers from your doctor, or if you were simply told "your labs look normal", and are tired of the trial-and-error approach, wasting time and money on random supplements and treatments, know that there's a better solution. You deserve to have the tools to learn how to manage your health issues, heal your body, and feel like yourself while living a life you love to its fullest potential.

I'm Denise Canellos, a Board Certified Nutritionist, author of Calm Your Inflammation, and university professor, specializing in effective nutrition therapy for cancer and chronic disease treatment. My husband George was diagnosed with colon cancer at 38. It was devastating for our family when George died from his cancer. I felt a pull to help others navigate the confusing world of healthcare and nutrition. After earning my MS in Human Nutrition, I passed my American College of Nutrition Board exam and started using science to help people like you get back their health and their hope.
