The Minute that Tina opened the door, I knew I was in the right place. Tina spent an hour and a half with me, going over the three week elimination diet. She had two paper booklets for me, to get me through the first three weeks. She went over every section, and term. She also answered every question I had. I will continue my health plan and supplements. I intend to touch base with her from time, to let her know how I am doing. I am very happy she came into my life, and my health is better from the experience.

I highly recommend working with Tina. I was struggling to lose weight and getting really frustrated with all the information out there. It was nice to learn from someone who is a trained registered dietitian nutritionist. The meal plan and recipes she gave me to try were really delicious and easy to make. Giving up my diet pepsi every day was the hardest! I have lost the weight and feel great. Wish I had talked to her sooner!

Experienced, Creative, flexible thinker, good listener, very knowledgeable, moderate approach. Tina is a great addition to any health care and wellness team! She helped me to be more organized and systematic with my elimination diet while I tried to expand my choices and pin down my allergic/sensitive foods. Her thorough knowledge of food chemistry and biological science make her a great resource for evaluating supplement and food components that may be causing issues. Her recipies are fantastic. Follow her on Instagram!

After meeting with Tina I was able to quickly make progress towards healing my Non-Alcoholic Fatty Liver Disease and Pre-Diabetes. She provided clear information about my nutrition, and how to optimize my diet. I specifically wanted a one-on-one experience, and I'm so glad I chose to work with Tina.

I cannot say enough good things about Tina. She is an amazingly knowledgeable nutritionist and chef. Not only is she full of ideas for healthy delicious recipes, she’ll also take the time to show you how to cook them (and will even make them for you if you want)! What’s more, her knowledge of disease-busting anti-inflammatory food/recipes is top notch. She will also talk about what you should and shouldn’t be buying at the grocery store. If you are looking to revamp your diet to makeover your health, Tina is THE person to go to. She’s also super friendly and down to earth, making the entire process fun and enjoyable. Cannot recommend her highly enough.

Tina is a very knowledgeable professional who takes the time to explain things and answer questions for you. When changing your lifestyle, it can be daunting and difficult; but Tina never made it seem impossible. She was thorough and supportive. I would recommend her for any of your dietary questions, changes, and needs. She was super helpful to me and in a relatable and practical way.

Jennifer Lazor

Tina gave great practical advice and was very informative. She helped me find an effective supplement/vitamin program that was very helpful. Overall, it was a great experience!

Tina helped me to lose weight, reverse high blood sugar, cholesterol, and inflammatory markers through realistic lifestyle change that I felt I could maintain. I was also able to discontinue my cholesterol medicine. She performed a resting metabolic rate test so I could see how many calories my body was burning, and also prescribed micronutrient testing so we could use targeted supplements as an adjunct to help me reach my goals. The prescribed strength training program has really helped me to build muscle, and favorably change my body composition. My doctors are very happy with the results, and so am I!

Vegetarian for 31 years and having grown up in a meat eating household, I've always been one to figure things out on my own when it came to my nutrition. I was running into some health issues so I knew I was doing something wrong...despite never being a junk food person and always being active. Working with Tina has been life changing. She is always available to answer questions and the plan she suggested I follow has been like magic. I feel better than ever. I would recommend anyone who is looking to feel better, lose weight, correct health issues, whatever your goal might be...work with Tina! She is an EXPERT!

Matthew Riordan

As a physical therapist, I know that to feel your best having a healthy diet is key. Even more important is having the right plan with the right foods, which may not be the same for everyone. Tina brings such a wealth of knowledge and experience, is always up to date on the latest research and is able to practically apply it on an individual basis to the patients that we refer to her. When working with Tina, our patients have had tremendous transformations which have opened up new opportunities for them to live an active and fulfilling lifestyle. IF YOU EAT FOOD,YOU SHOULD WORK WITH TINA!

Meetings with Tina, focused on developing individualized anti-inflammatory diet plans and nutrition programs. We were very impressive on how she explains the interaction of food and its nutrients with the human body and how it can cause different results. She teaches the benefits of healthy eating in a clear and understandable way. The plans provided are easy to follow and the food enjoyable - both of us have lost significant weight and feel better over all.Tina is an excellent coach and teacher, very understanding, patient and encouraging. As a result we are following a healthier lifestyle and making better food choices - so glad we found Tina.

I would highly recommend this Tina! She helped my sister, Linda completely restructure her diet in a way that was both realistic and sustainable. Instead of focusing on restrictive eating, she created a personalized plan that fit my sister's lifestyle and health goals. Tina is knowledgeable, supportive, and took the time to explain the reasoning behind her recommendations. Thanks to Tina's guidance, my sister has developed much healthier eating habits and feels better overall. We truly appreciate her professionalism and dedication, and would confidently recommend Tina to anyone looking to improve their nutrition and overall well-being.

I have worked with Tina for the past 13 years and she has helped me with my strength, posture and diet. I am 75 now and I have never felt and looked stronger and healthier. She has a complete understanding of nutrition and its role in physical fitness. We discuss current issues about medication and fitness while working out but she is always available to discuss any concerns. In my opinion, she is the perfect trainer as she has all the available tools to help anyone achieve their goals. She also a very decent and honest person.

I’ve been lucky enough to work with Tina for over 13 years. She has been an incredible resource for my personal fitness, nutrition, and overall health. She consistently provides amazing recipes and high-quality supplement recommendations, always focusing on healthier alternatives. What I appreciate the most is how well she listens to what my body needs during our training sessions while still encouraging me to push beyond my comfort zone in a safe way. Her approach is both supportive and motivating without ever feeling overwhelming. I’ve also completed her 2-week Fat Flush program and saw significant improvements in both my overall health and weight. I truly can’t recommend Tina enough for anyone looking to make a lasting, positive change in their lifestyle.

Tina Marinaccio is an exceptional nutritionist. She has supported my entire family with personalized, science-based guidance—from a Fat Flush quick start to weight loss and probiotic recommendations post–GI surgery to nutrition plans for kidney disease and guidance while on GLP-1 medications. Tina combines deep clinical expertise with practical, easy-to-follow advice. She truly tailors her recommendations to each person with care and understanding and delivers real results. Highly recommend for anyone looking for expert, personalized nutrition support.

We already Came in, knowing a heck of a lot about food and nutrition, and Tiina took us a major step further forward to manage chronic heart disease through better nutritional choices and investigation of lesser known tools out there. Would highly recommend her!
Lisa Ambielli
Dr Tina was amazing! Not only did she help me loose 13 pounds over a two month period, but my energy levels and sleep patterns are better than they have been since pre-covid days! Highly recommend her!

I had a great experience working with Tina to get my nutrition streamlined to not just lose weight, but redirect what was on my plate, as well as the proportions. In less than a month, I lost 15 pounds and was not craving at all. I started to cook like a chef and even impressed myself with how I have kept it up. She helps identify small changes that yield big results, as long as you are willing to do the work with her help. I can't recommend her more highly. She is friendly and great at what she does.
