I had the pleasure of working with Rob as my nutritionist and found the experience incredibly valuable. He took the time to understand my goals, lifestyle, and health history, and created a personalized plan that was both realistic and effective. Rob is knowledgeable, supportive, and easy to talk to. He makes nutrition approachable and sustainable. I highly recommend him to anyone looking to make meaningful, lasting improvements to their health.
