What Our Patients Say
Maria has been such a pleasure to work with. She is easy to talk to and very accommodating. She listens to you and will adapt her plan to fit your needs. She checks in and teaches you how to cook healthy meals. I lost 6 pounds in 2 weeks by following her fundamentals (ex. drinking water, meal planning, not eating a few hours before bed, getting rest). I am a self employed mom of 2 very small children and her plan works for me.

Gail Cunningaham
Maria is so helpful! I started going to Dellonutritionals once a week after the birth of my 4th child. Maria helped me lose 25 pounds in a healthy way that fit into my busy lifestyle. She gave me great, healthy recipes that even my kids would eat. It's been over a year since I lost the weight and I have been able to keep it off thanks to her tips and advice.

I never had a weight problem in my life. I never had to think about dieting. COVID changed everything. I packed on 15 pounds from stress, and comfort foods. I needed help, and reached out to Maria Dello. She found the perfect plan for me, including diet, exercise, and meditation. The weight came off at a controlled rate, and I learned so much about nutrition. Over the course of one month I lost 15 pounds, and got back my strength, and energy as well. I highly recommend this dedicated nutritionist.
