Dayna has over 10 years of medical experience and is a pioneer in the field of Functional Medicine in both experience and knowledge. Dayna has been integral in the successful launch of two Functional Medicine businesses and continues to master and study at the Institute of Functional Medicine. She advocates a holistic approach to health that focuses on the whole person and the root causes of disease.

“My main goal is to treat patients in the most natural way, using real food, lifestyle modifications, supplements, and nutritional IV Therapy that give their body the nutrients it needs to heal itself. I focus on balancing patients’ bodies to lower inflammation, let go of excess fat, water, and toxins they may be holding onto, and provide them with anything they need for optimal health.

It is so rewarding to watch the amazing transformations in my patients. Most importantly, my patients are left with an education for a lifetime and feel empowered to maintain their new health because they understand what their bodies’ needs are and why.”

Dayna practices what she preaches. She believes, as Hippocrates once said, “Let thy food be thy medicine and medicine be thy food.” In her spare time, you can find Dayna on a yoga mat, trying out new healthy recipes, traveling, and spending time with her family.

Randi Cestaro

Director of Nutrition

Randi is our Integrative Health Coach. She has been certified as a Holistic Health Coach by the Institute for Integrative Nutrition, and is a certified yoga teacher. Randi also holds a Bachelor of Arts degree from Johnson & Wales University...

Randi’s journey began when she was diagnosed with Polycystic Ovarian Syndrome (“PCOS”) in her twenties. Her periods had vanished, she had enlarged ovaries, was tired all the time, gained weight, had painful cysts on her ovaries and breasts.

By embracing and personally practicing what she was learning in her studies to become a holistic health coach, Randi drastically changed her diet and lifestyle, and within six (6) months her PCOS symptoms went into remission. Her menses cycle returned to normal, the pain subsided and her mood stabilized. To her great surprise, Randi’s physician confirmed that her ovarian cysts had disappeared and her ovaries had returned to normal size.

Randi is self-motivated, confident, and a nurturing coach with a proven track record of helping clients mitigate their symptoms through effective nutritional practices. She has over fifteen (15) years of experience in providing nutritional guidance to patients with PCOS, diabetes, infertility, hormone imbalances, irritable bowel syndrome and weight loss issues. Randi has the innate ability to distill complex nutritional data into accessible information that her clients can understand.

She has given talks on various nutritional topics at the United Nations, Asphalt Green, and at the Montefiore Institute.

See Beyond™ Medicine is proud to have Randi as our Integrative Health Coach. Come see for yourself how caring and understanding she is about your health goals. We all look forward to meeting you.
