I invited Marissa to participate in my company's Wellness Fair to provide information about nutrition. She was very friendly and provided great information to my staff. From her attending our event, I have scheduled an appointment so she can help me with my personal wellness.

I consulted Marissa because of some borderline cholesterol readings that I was hoping to lower through diet and exercise. She's helped me learn the Mediterranean diet and has given me some great suggestions. Nothing feels restrictive and I like her positive approach. Marissa is knowledgeable, kind, and compassionate. My recent blood work showed the cholesterol numbers I was worried about are nudging downward. My doctor told me to keep doing what I'm doing.

I needed some menus reviewed and approved for a summer camp. Another dietician was recommended, however, it turns out they were not credentialled. There was a tight time factor and Marissa was able to complete the job in a timely manner. She was thorough and asked all of the right questions. Marissa has a great understanding of what is an appropriate menu for active youth. She was quick with her responses and very easy to work with. We will use her again, and I am happy to refer others to her.

Marissa was so helpful in our first session together. She's incredibly knowledgable and compassionate in her approach. I really appreciated her guidance with a challenging dietary situation!

Disappointed there wasn't a follow up on our initial consultation and didn't receive any handouts or information to take away. During the consultation, just basic nutrition guideline was discussed that my daughter and I already knew. If that was the standard protocol then we should have been told. We paid out of pocket for the session which wasn't cheap so I felt it wasn't worth it. I ended up finding a dietitian/nutritionist who specialize in sport fitness that my daughter can relate to better and was more enthusiastic and showed more interest in what my daughter liked and made her feel more relax. My advice is to go with your gut instinct and continue the search for what's best for your child. Don't settle. For me it was the lack of follow-up that bother me most.

Highly recommend Marissa! I was in such a bad place with my body and my relationship with food when I first reached out to Marissa at my therapist’s request. She is kind, thorough, supportive and compassionate. I never felt judged at any point. She makes you feel comfortable and is open to listening and helping in any way she can. I am in such a different place than when I first started seeing her. I am very grateful to her and all she’s done for me!

I highly recommend Marissa! She has helped me so much with learning how to become an intuitive eater. I am healthier, have more energy, have a much better relationship with food, and have such a great outlook now :)

Marissa is amazing and my life would not be the same without her! I highly recommend working with her! She is kind, compassionate, thoughtful and caring. She never made me feel nervous or judged. She gladly teamed up with my therapist to provide me with the best care possible. She even went above & beyond to ensure she could continue to provide me care when I was out of state. Through our work together learning about and implementing Intuitive Eating, I have finally found peace with food and my body - something I wasn't sure would ever be possible - but with Marissa's gentle and personalized approach, she guided me along this journey and I am forever grateful.
