Diane May provided extensive information and background about nutrition, as well as how each vitamin supplement works in the body. I left her office with a solid meal plan and detailed strategies to reduce inflammation. She is thorough, thoughtful and a good listener. I am grateful for the knowledge she shared.

Diane May was very knowledgeable and clearly explained what I had to do keep my CKD from getting worse. It is overwhelming but with her support I believe I will be able to accomplish what I came to see her about.

Diane May is an excellent and informative nutritionist. She answered all my questions and offered me advice on long term goals and ways to achieve them. I had an outstanding visit with her!

I was referred to Diane by my doc in White Plains eco system. Mid May 2026, I had a rude and terrible experience with her office team. Utterly unprofessional staff. Without seeing her I left the office. I received a call after a few weeks apologizing and asking me to give her another chance and care to visit. I refused to waste my time and resources. Now, in July I am finding out the doctor charged my Insurance $500 plus for a visit that never happened. What an unethical team of healthcare service providers! Apparently they are so desperate for patients that even without seeing a patient, insurance is charged. White Plains Hospital Team should be investigating this practice and it's billing nuances. I will be advising my insurance.

Diane took the time to do her research on my medical history and then ask a lot of questions which I very much appreciated. I look forward to our follow-up conversation on progress against goals.
