For the last several months, I have been working with Marinna on my journey to having a healthier lifestyle. She is amazing to work with! I am a mom of two, one kid with food allergies, she has helped me create balance meals not just for me, but for the whole family. She has become a great source and a great motivator for me to continue to eat healthy and ensure my little kids have a good relationship with food.
