I have absolutely no idea why there are negative reviews. I just started treating with Angela and she is working effortlessly to cull through my records and issues and get me on a path to health. I highly recommend her!! And I say this after seeing 35+ practitioners, including nutritionists, naturopathic doctors, medical doctors, etc., all within a 16 month span. Angela is on point and creates a clear, concise plan. She is excellent. read more

I am very disappointed that all reviews are not showing. These bad reviews are 1000% invalid based on my experience with Angela. She has been totally flexible with me, spreading 15 weeks over any period of time that my body and life require. She is truly investing in making your whole body healthy and making your changes personalized. She will work through every hump with you. I am a new person because of Angela and all of her personalized guidance. I live all the way across the country and she finds ways to ensure that my support feels local. My husband is a physician and well respected in our community and I should hope that frivolous people with untrue Yelp reviews will never effect his line of work. People like Nate apparently review more frequently so his reviews hold higher significance, this I am very disappointed about and it makes me use this site very differently now. read more

Angela is all marketing and little substance, overpriced in both her fees and supplements, and deceptive about both. She markets herself across numerous websites: http://www.cleanandleansystem.com/, http://www.nutritionnorthwest.com/, and http://siboguru.com/ to name a few. Her hundreds of 5-star reviews on her website don't align with any independent review site such as yelp. I saw her for SIBO, where she used her SIBO Guru diet, which was basically a FODMAP diet written out on a picture of a flower. She recommends a lot of supplements. Whenever possible, she uses supplements from obscure brands that are very difficult to comparison shop for pricing. But the worst part is that I found comparison shopping for her supplements to be impossible because she wouldn't actually tell me the prices she was charging for the supplements. She takes your credit card information at the beginning of your time with her and then starts charging her fees as well as supplement purchases directly to your card. I asked her for a bill to explain the charges so that I could order some on amazon instead. I actually didn't care so much about the price at the time as I cared about the convenience of getting them to my door in 2 days. She insisted that her prices were the best I could find and then switched me to even more obscure supplements that weren't even available on Amazon. When I extended my program with her, I again asked her for a bill, but she did not provide that. Instead, she raised the fees without explaining the charges, and when I put together exactly how much she was planning to charge me, I asked her to stop automatically debiting my credit card until she could send me a bill for the charges. A month went by without a bill. I checked in with her multiple times through the month to ask for the bill and remind her that she was no longer authorized to charge my credit card. At the end of the month another charge appeared on my credit card with no bill and no services during that month. I was never sent a single bill for the 15 weeks and roughly $3,000 I spent with Angela. I hope I can save you some money. If you have IBS or SIBO, instead of consulting with Angela, download the Monash University Low FODMAP smartphone app for $15 and walk through the diet with them or talk to a real doctor. Don't be fooled like I was into trusting Angela with your health or your credit card. read more

I have SIBO, IBS-C and pelvic floor dysfunction and have been living in gastrointestinal hell for ten years. I've been to the Mayo Clinic and top NYC gastroenterologists to no avail. Angela is the only person who has made a substantial improvement to my quality of life. She is truly a SIBO GURU! In the year leading up to my wedding, I was terrified that a SIBO flare-up would ruin my big day, and, thanks to Angie, it didn't. She was an absolute Godsend. Through all my experiences - and all the thousands of dollars spent - trying to understand why I have this horrible, recurring condition, and how best to live with it, Angela has been the only person who has really evaluated me holistically. She is a one-woman team, trained to analyze a patient from every angle rather than in a vacuum. My experiences with doctors were frustrating - I would spend months waiting for an appointment with a world-renown expert only to get 7 minutes of her time and another xifaxin prescription, without any nutritional advice whatsoever. Even if I got a nutritionist referral - and I did see a nutritionist at Cornell for awhile - all the nutritionists would do is put me on a low FODMAP diet. I have read the Patsy Casos book and done the elimination diet and most certainly did not need a nutritionist to tell me how to do that. Angela is NOT this type of nutritionist. She is extremely well-studied and may as well be a full-on M.D. She is as smart as any doctor I've met throughout this process, and actually takes the time - sometimes on long calls or through long emails - to LISTEN to your entire story and get the full picture of you as a patient. She listened to my symptoms and read my journals (and boy were those journals detailed) and then told me what labs/bloodwork to order and which tests to have done. She was then able to accurately analyze the results - so much so that my gastroenterologist and an endocrinologist both independently complimented her work to me. Through Angela, I was able to learn that I have low T3 (a thyroid hormone) - which I have never known before - and get on the appropriate supplements for adrenal fatigue. One note on the supplements: Angela does not private label her supplements so that she can upcharge like some other nutritionists (e.g. Kimberly Snyder of the Beauty Detox Diet) do. She tells you the exact name and brand, and you are free to order them on Amazon or anywhere else you can find them - in no way are you trapped into buying anything from her (although most often her website is legitimately the cheapest source). One of the reviews on here made it sound like Angela is constantly trying to get you on more and more supplements but my experience with her has been the opposite - she has worked hard to reduce the number of pills I have to take in any given day. Angela has also always made herself available to me in an emergency. I went on a food tour (like an idiot) in Montreal a few months ago and came back having a massive SIBO flare-up just a month and a half before I would have to fit into my wedding dress. Angela and I had already stopped working together through a formal program, but she made herself available and put me on an elemental diet for one meal a day, which really helped to get me back on track. Working with Angela is definitely expensive, but I can honestly say that for me it's been worth every penny. If you have SIBO and you have the means to work with Angela, I can't recommend it highly enough, particularly if you've been spinning your wheels trying to eradicate this stupid condition without long-term success. Please feel free to PM me for more information, or just to vent about SIBO!! Always good to meet others who can relate to looking 7 months pregnant after eating a darn plum. read more

I am not affiliated with Angela Pifer in any way except as a client. I was diagnosed with a rare blood disorder, Aplastic Anemia five years ago and given three to six months to live. I found that TCM would be helpful. However, after years of getting TCM herbs, and getting better, I still had stomach pain on a regular basis, and felt there was still an issue I had not uncovered. I met Angela through the myriad of research I continue to do. I had looked at FODMAP before and could not make it work for me. The first time we spoke, she explained some things that clarified what was possibly going on, and when I tried them, I felt better and knew I had a good coach who could lead me and who would listen to me. I focus on results...and results that happen rather quickly...within days. My "blood" disorder was more of a malabsorption issue, and I needed to get clear on what the fine points of understanding food were for my body. Alleviating gluten and sugar (which TCM doc said weren't a problem!) (Oh, trust me, they were!) were just the beginning five years ago, but there were other things that were helpful, and some things to be avoided, that I was unaware of. (I knew I couldn't try raw food...I would NEVER be out of the bathroom!) Angela was very patient with me (I have tried soooo many things, and so I have an abundance of knowledge, it is hard to help me move further) and we discussed and decided on courses of action and I went forward with her. Because of this, the pain ceased, and I have lost about 10 lbs (I was at least 20 lbs overweight) and my blood numbers have stayed consistently normal when before it was an up and down thing. Since I have tried so much, I was thrilled when she gave me a plan, gave me ideas of food to work with, kept me on my food journal, and we could discuss what had happened and why. It was eye opening! I had no idea about fats and how much they impacted me, and benefited me! I have learned so much from her on how to monitor my progress and how to be consistent and not anxious about my eating, my blood numbers and my health. This is a very painful and lonely road to travel by oneself because often there are repercussions (diahrrea five times a day or constipation, fatigue, inflammation etc.) for eating certain things, and one doesn't know why. So having a coach who "gets it" and can explain how things happen (in MY body) is crucial for success. Even if I complain and whine and occasionally fall off "the wagon" (yes, I threw the rest of those potato chips away). I don't buy much in the way of supplements, and not much has been suggested to me to buy from Angela. But the ones I do buy have been life savers. Again, I have worked with other coaches, and have not gotten the clarity, and the results that I have gotten with Angela. This is a very individual course. Each body is TOTALLY different and has to be looked at by the coach, yes, but by the individual too. It takes a lot of responsibility to stay on the path and note what works and what doesn't when you have had years and years of mistreating the body. In my case, it is life and death. I can't afford to play around...ALL of this is MY responsibility first, no one elses. I don't continue to pay for something that is not working and then complain that someone else is the problem. Angela has been nothing but a huge HUGE help to me and my ability to digest food, and no, I don't like it that I cannot eat certain things, or do consistent exercize, or keep getting water into this body...but all of those are a small price to pay for staying on this planet after 64 years. Thanks to Angela, my body is not a mystery, and I feel it is truly a gift to have her walk this path with me. read more

Word's cannot express my gratitude for Angela. Her knowledge is unbelievable and her services have been well worth the cost. Since my mid 20's I have had a dx of IBS. I developed hypothyroidism, suffered w/ joint pain, heartburn, constipation, low vitamin D & B and depression. I was on numerous medications yet continued to feel worse. After being diagnosed with food allergies, fructose intolerance, and SIBO I found Angela through an on-line search and now an feeling best in I have felt in years. read more

Although she seems to be knowledgeable, and had generally good advice - she was overpriced and trying to push her supplements and services. A better rendition of her basic advice - "eat whole foods" is found in the Michael Pollan book food rules. Read that instead. She also left me with the impression that her services would be covered by insurance, and I ended up having to pay half of the nearly $1K out of pocket for one month of consultation. Her services included were that she was "tracking" a daily meal plan and that we would talk on the phone for 30 minutes once a week. - and I could email her with questions. I'm not sure if she ever tracked anything until the day of our call. It sounded like a good investment, but I never needed to connect with her outside of our regularly scheduled call. I also found her supplements priced better at Super Supplements, even though she said she has the best price. Seek out a nutritionist with the help of your general provider for better results. read more

I was referred to Angela by my primary care physician after over a year of unexplained weight gain. No amount of dieting or exercise was helping and the doctor's only response was that I was turning 40 and "that's what happens." I didn't buy it. I enrolled in her 3 month program and the results were amazing! Angela has extensive knowledge of how the body works and how different combinations of foods, lifestyle, medications, and sleep patterns affect your health. My program was tailored specifically to me with help and support from Angela the whole time. I'm not saying it was easy! She definitely holds you accountable by checking your journals a couple times a week and follow up phone calls at least once a week. Besides changing how and what I ate, I had to make some lifestyle changes to improve on sleep, the way I exercised, and decrease stress levels whenever possible. Being self employed this is really difficult but being made aware of these things helped me make some changes, even if they were just small ones. She is there to coach you and guide you but in the end, the work is all on you! She did recommend several supplements but all were to support my own program. I looked around online to see if I could get the supplements elsewhere and turns out her charges were all a buck or two cheaper. She also gave me receipts to turn in to my insurance company but even though my policy states that nutritional counseling is covered, I could not get them to cover any of her costs. Shame on the insurance companies but no blame to Angela. She made me aware right away that she didn't charge insurance companies and that them denying coverage to me may be a possibility. After seeing my progress, several friends and colleagues have also worked with Angela and all were pleased with their own results. She is always there for questions, support and follow up care and even has a website with lots of exercise and food ideas and more. I highly recommend her. (and do quite often!) read more

I just received my final SIBO breath test and it is confirmed, it is negative after 6 months. Thank you Angela!

I concur with others that Angela is all marketing and little substance. Much has been said about her pushing her own products with the highly questionable argument that Amazon does not offer the same quality control as she does (which does not prevent her from recommending Amazon for a few products that she -- for whatever reason -- cannot offer (like Allimax). The real issue is (i) her deceptive claim to be the Siboguru and (2) the gap between the promised and the actual quality of services she offers. 1. Everyone who has been diagnosed with SIBO will soon find out that there is a very little that is certain regarding the diagnosis and recommended treatment. To begin with, many people meet the diagnostic criteria for SIBO, but show no symptoms. The diagnostic criteria and their interpretation also vary significantly. There are the famous hydrogen and methane breath tests, but for the latter positive tests vary from more than 3 ppm to more than 12 ppm at the 120 minute mark. The latter is important as treatment of methane-dominant SIBO requires a different treatment than hydrogen-dominant SIBO, to be precise methane dominant SIBO requires two antibiotics (one of which: Neomycin with a whole range of common side effects), while hydrogen-dominant SIBO can be treated with the easily tolerated Rifaximin. A first choice of treatment may appear to be antibiotics, as they (according to many studies) promise fast recovery (2 weeks), while herbal treatments may require 2 or 3 months of very high doses of supplements many of which cause severe side effects (Herxheimer and others). Angela had no qualms insisting I need to be treated for methane-dominant SIBO because my Methane levels were at 8 ppm at the 120 minute mark. However, I soon found out that the most reliable source of guidance for the interpretation of SIBO tests (an article by Siebecker and Sandberg-Lewis of 2014) recommends using the 12 ppm criterion. Moreover, the North American consensus on the interpretation of breath testing of March 2017 (A. Rezaie) clearly indicates that 12 ppm is the proper benchmark, especially if the patient (like me) presents no evidence of constipation. Hence, only Rifaximin would have been needed, if one were to go the antibiotic route. Yet, Angela insisted on treating both hydrogen and methane levels, which in my case meant the long herbal route as I could not risk taking Neomycin due to problems in the past with peripheral neuropathy (a feared side effect). Only, after much back and forth and after unearthing the above-referenced article by Siebecker/Sandberg-Lewis did she accept that my case was hydrogen-dominant.What was extremely aggravating and even disturbing was that she insisted on the methane diagnosis as scientifically proven, when it was anything but that. Moreover, she had no qualms charging me for a 'bonus call' for the back-and-forth on these points when, in the final analysis, this was all about correcting an error for which she was responsible and which I had to rectify through my own research on the topic. Towards the end of my treatment, the dangers of this approach became even more apparent: The lack of progress in reducing my gas levels after almost 6 weeks treatment (first with antibiotics then with herbs) left me in doubt that I was on the right track, notwithstanding Angela's assurances. I finally learned that a competent naturopath (Dr. Kannankeril) who had studied at NMU in Oregon practiced in DC, and made an appointment with her. Dr. K shared my concern about the lack of progress, and recommended the Elemental Diet--an approach much promoted by Ellen Siebecker who is usually one of the pundits on which Angels relies. Dr. K also recommended I continue with the herbs in parallel (something not advised by Siebecker). While my hydrogen levels continued to be too high after all this, they had fallen a lot and, what counted the most, my symptoms were all but gone and I could finally eat again everything I wanted. Angela kept arguing against the Elemental Diet till the end. All I can say: it worked ! Much like Siebecker predicted. Good I did not listen to Angela. 2. Angela promises individualized services. In reality, she does not care at all about the patient, but counts obsessively every minute she spends on you. When I had a SIBO flare-up in India in February 2017, she left me stranded telling me essentially I should shut up and ride it out. All I needed was some advice on how to deal with my terrible stomach pain. She also never spoke to my primary care physician or Dr Kannankeril, even though she claims that she will work with your doctors as part of the 2 month package. There is much more I could report, but yelp does not allow enough space . read more

My husband and I have worked closely with Angela for many years and have always been impressed by her knowledge and professionalism. We own a personal training studio and have often referred clients and family members to Nutrition Northwest for a variety of reasons. Some clients are seeking simple nutrition plans to help clean up their diet while others are seeking help with bigger health problems like IBS or SIBO. They always come back thanking us for the recommendation and are happy with their results. Our personal philosophy is to eat whole foods and only use supplements as needed and Angela's own philosophy lines up with our own. She does recommend supplements but only when they are absolutely necessary to help a client achieve results or eliminate pain. I use Angela as a source to purchase my own supplements because her prices are always fair and never inflated. One time I received a powdered vitamin supplement that I simply couldn't stomach and she not only refunded my money but also sent me a different vitamin asap. read more

Angela is extremely patient, understanding, knowledgeable, and validating. I sought her out to treat SIBO that was only getting worse despite conventional treatment, as well as multiple alternative medicine practitioners. We still have a ways to go, but after only a few weeks, I'm feeling the best I've felt in a year. Angela acknowledged the SIBO, but looked at all my symptoms to find other root causes. While she does recommend supplements, I've never felt that she pushed her own, and most of the time encouraged me to use up comparable supplements from what I already had purchased elsewhere. She also often sells needed products at a discount or even at cost! I did my research to price compare and found her store to be fare. Still going strong in the early stages of our plan, but from what I've experienced, I have complete confidence in Angela. I finally have hope again that I may heal one day!!! read more
