FOLLOW-UP Last week I had my blood work done. All I have to say is “Thank God” for Juliana Mazzeo . My A1C came back 5.0 !!!!! My fasting glucose 95, my AST and ALT were well within the safe range. I am beyond grateful for Ms.Mazzeo guidance/recommendations, she set me straight , No BS !!! Sat me down went over what I needed to do (not what I should do, but what I needed to do or be diabetic) . Yes I needed to make a life style change , stay away from sugar and certain foods. But the hard work paid off! I am forever grateful for Juliana Mazzeo, she is a shining example of excellence in her field, and is an incredible caring human being. Again I highly recommend Ms.Mazzeo 5months ago Four months ago, I just didn’t feel right. I went to my doctor for blood work, and she told me everything was "fine," just that my blood sugar was a little high and I should watch my diet. I knew in my gut there had to be more to the picture than that simple answer. That's when a friend recommended Juliana, and I’m incredibly glad they did. Juliana didn't just glance at my results; she did a thorough diet assessment and evaluated my blood work using comprehensive Functional Ranges, not just the basic standard ranges my doctor used.0 The phrase that stuck with me was when she told me my liver was "not happy." She explained the seriousness of my situation: I was borderline diabetic. My A1C of 6.1 is not fine; it’s just 0.4 points away from a diabetes diagnosis. My fasting glucose was 146 (diabetic threshold is 126), my lipids and triglycerides were completely out of range, and my "great" vitamin D level was actually dangerously low. Juliana gave me a clear, three-month diet and supplement protocol. She didn’t coddle me! She read me the riot act: "If you are not 100% committed to this, don't waste your money, your time, or my energy." / Thank God she said that; I needed tough love, not coddling. I recently had my labs redone, and they are now in optimal Functional ranges. I’m thrilled with the numbers, but more importantly, I,ve lost 17lbs, I feel 20 years younger. I’m full of energy, I sleep soundly, I’m stronger in my karate class, and I have the energy to truly engage with my teenage daughter. I am incredibly grateful for Juliana’s expertise and honesty.

Dear Juliana! I always knew how incredibly knowledgeable you are , a go-getter, and super professional. I truly sat in passenger seat and let you do the driving. You went above and beyond to find the perfect remedy for me. There's not another person out there that could've provided me with the ease and comfort knowing we were making all the right decisions! Your exceptional personal approach created a strong sense of confidence and trust. You really became an ally, friend, and advisor and helped me navigate a difficult health issues. I felt like we were constantly “ahead of the curve” in every step of the process, which was entirely due to your thoroughness deep expertise and dedication. I am writing all this, not just to express my deepest thankfulness, and appreciation, but letting you know, that you exceeded my expectations on my healing journey throughout the entire process of every stage including just a pure heart advice even of the personal matters. I cannot imagine a better experience and cannot wait to refer other people moving forward with your absolutely warmest heartfelt support on all levels possible. Alla Soskin.

Juliana is the best there is. I used to have trouble gaining weight. At one point I was so underweight, I was being a danger to myself. A few months ago I decided to see a nutritionist because I was stuck. I didn't know what I was doing and I was causing so much harm to myself, and after my first session with Juliana, I was so glad that I found her. Juliana was able to identify a lot of underlying issues that I had; not only did she address my relationship with food but she was able to detect some very important consequences about my mental state that I hadn't really thought about before. I was under a lot of stress but I didn't know it. And our first session was essentially a wake-up call. With my comfort levels in mind, Juliana used her expertise to put together a meal plan that I was able to follow. Over the course of my nutritional journey, she went over my blood-work and pinpointed some vitamin and mineral deficiencies that my doctor dismissed. She walked me through the process of taking the supplements that I needed to help reduce my symptoms, and I have seen so much improvement thanks to her. I have less body aches, I've been sleeping better, and most importantly, I gained 12 pounds! Juliana knows what she's doing and I highly recommend her. Thanks to her guidance, I'm committed to getting better no matter how long it takes. ♥

I am 52 years old and have been struggling with my weight for years. I have done numerous diets and was unsuccessful. I started hA2cg with Juliana in March 2018 and I did the program for 40 days and lost 23 lbs and in September I did another round of hA2cg for 40 day and lost another 20 lbs. I didn't feel hungry and was motivated to see the weight drop everyday. I feel amazing and full of energy. I couldn't have done it without the support and encouragement I received. The program was explained in detail and as long as you follow it - you will be successful. I recommend Juliana for anyone looking to lose weight. She is amazing !!!

Julianna is amazing! I started with her about 3 months ago. She has helped me so much and i have never felt better. I have done the hcg diet in the past and I was always unsuccessful with keeping the weight off. This time doing the HCG diet under Juliannas supervision i have been able to keep off and maintain my weight. I have lost 14lbs. She provided me with the proper guidelines and got me better results this time around. She is so thorough and is always there when you need her. I love Julianna and i am so glad i found her! ❤️

So where do I start? When I met Julianna I was suffering with allergies for 20 year. When we started treatment I didn’t think I could get better because I believed if I was allergic to something how could I get healed. But shortly after my allergies were gone! I’m feeling great and never felt better! I took my mom she had knee pain to the point they told her she needed knee replacement surgery. After being treated her knees are back to normal and she is walk around going up and down steps with no problem. She also was getting forgetful and confused Julianna also treated her for this she is now feeling better and back to normal. All I can say is truly amazing!! Best thing that happened to us is finding Julianna!!

I have struggled with digestive issues for 15 years and been under the care of Nutrition Wellness Center for six years treating IBS and fluctuating weight changes. Juliana is the only person I can trust who takes her patients conditions, will get to the root of it and make the appropriate changes holistically to a better you. Last October, I went on the HCG Program. I've been on this program before and had great results. This last time, the results were amazing! Juliana has perfected the steps and coaching. I lost pounds and inches, and have kept it off 7 months now. My body as a whole has completely changed. The clothes that give me some comfort and wiggle room are way too huge. They fall off my body! And, the skinny clothes are also too big!! I need a new wardrobe, but in a good way! If you are struggling with your weight, IBS or any digestive issues, please make an appointment with Nutrition Wellness Center - go for the consult. It's a life change not a quick fad diet, but you will not regret it or look back and say what a waste of time.
