Kidney Disease Certified Nutritionist, Renal Dietitian in Long Island

Medical nutrition therapy is fundamental for those diagnosed with chronic kidney disease or renal insufficiency. When kidney function is compromised, the kidneys do not filter or remove waste properly. Implementing a renal diet may help to promote kidney function and slow the progression to kidney failure.

Over the past six months that I have been seeing Nacny, she has been very helpful in hepling me lose 31 pounds. She understands very aspect of what I needed and how to accommidate them properly. With Nancy's help I have been able to change my lifestyle, eat healthier and change and treat my medical conditions very differently and for the best. I would highly reccommanded Nancy to anyone that has tried diets before and has not succeded and who has a lot of different medical conditions that make it difficult to know what to eat and what not to eat.

I was hesitant at first to start seeing a nutritionist. I was very comfortable with my poor eating habits despite being upset about my weight; however I knew I needed to make a change.Nancy was very understanding from the start. Before meeting with Nancy, I had been in a constant cycle of over-restricting myself to lose weight rapidly, followed by binge eating and gaining it all back plus some more.Over the past year and a half, Nancy has helped me discover normal eating. She helped me understand my hunger and my fullness in addition to helping me choose better food options.Nancy is very dedicated to working with you and helping you achieve your goals. She doesn’t just help you reach your goals — she helps you change your perspective of food and eating for the better. What you learn with Nancy is not temporary — you will carry it with you and practice it throughout your life.I have lost almost 70 pounds since first meeting with Nancy and continuing on my journey. I highly recommend working with her.Nancy, thank you for all of your help!

Although I was unlucky when I developed some health issues, I was very lucky to find Nancy Mazarin, a skilled, intelligent, caring nutritionist. I saw lots of doctors but she was the one who came up with the diagnosis that finally led to my improved health. She was always available when I had questions and was even willing to meet with me one weekend when I was struggling.
