Dr. Mach is a wonderful doctor. I went to see her for acne and I am so grateful that I did. She is knowledgeable and very thorough, taking her time to make sure you understand test results, why you are experiencing symptoms, and how the treatment plan will help. She is always more than happy to answer any questions and really cares about her patients. Skin issues can sometimes take time to solve, but she will work hard to help you find the solution. I have healed so much since I first started seeing her and I cannot recommend her enough. read more

I saw Dr. Mach for just under two years, and the only reason I am stopping is because I am moving out of California. If I weren't leaving, I would absolutely continue seeing her. I first came to Dr. Mach when my health was at its absolute lowest. I was dealing with severe gut dysbiosis that was wreaking havoc on my skin. While I've always had eczema, it had historically been mild. Suddenly, I was experiencing painful, burning rashes all over my body. Before finding Dr. Mach, I tried everything--including conventional biologics like Dupixent and Xolair--but nothing provided real, lasting relief. Dr. Mach's meticulous treatment planning changed everything. She is incredibly kind, attentive, and empathetic. While healing took time, and I concurrently saw a dermatologist to help manage acute symptoms, I entirely attribute my deep healing progress to Dr. Mach. For the first time in years, I have just experienced about two months of mostly clear skin--something that felt like an impossible dream two years ago when this was severely impacting my quality of life. If you want to partner with a practitioner who genuinely cares, actually listens, and helps you identify the root causes of your health issues, there is truly none better than Dr. Mach. I cannot recommend her enough. read more

I went to see Dr. Nancy for fatigue and to help with moods. I was in therapy and my therapist thought I had mild depression so suggested that I try an anti-depressant. I wasn't sure if that was the route for me so I thought I would try naturopathic medicine. We ended up running a test for neurotransmitters and it looked like I had anxiety more than depression, which made sense to me. Her treatments include diet and lifestyle suggestions as well as natural medicines. It has been 3 months and I feel much less anxiety. I am calmer and don't stress when I have upcoming social situations, which used to stress me out a lot. I was also very tired before my first appointment. Dr. Nancy found that I had low iron stores and we also treated my adrenals. I have more energy now. I used to meditate and get super sleepy because I was so tired. Now I meditate and don't get sleepy. Plus I don't feel like I need a nap after lunch. I highly recommend her. She is thorough and explains everything so you understand why she is recommending a particular treatment. read more

I had a very old gastric issue which I wanted to cure once and for all. I tried variety of medicine both allopathic and alternative medicine, but it hasn't gone completely away. I went to Dr Nancy for this hope, she is very easy to reach out, listens to all the concern and organise treatment based on our unique situation. I am so impressed with how she goes about each test reading and explains in plain language which I rarely see with other doctor. those test are very thoroughly researched and treatment is advised based on that. She never rushes to finish the appointment.. She explains from the beginning about payment option and is very clear from the start. First phone consultation was free where she tries to know my health history and see if she can help or not, based on which she laid out plan if we decided to move forward. After few session for about 6 month I feel much better, but I had a appointment with dermatologist for skin rashes, it was my bad I forgot to inform Dr Nancy and started taking anti biotic prescribed by the other dermatologist which brought back my gastric issue again! It was my bad.. Now going with Dr Nancy prescription again. Another thing I forgot is how Dr Nancy determine some of the food to avoid and also combination of food to avoid which I think is very impressive, in my case I should not eat fruits and eat sugar within 4 hours time.. That explains my problem with fruit juice which as both together is harmful causing bloated stomach and acid reflux... I highly recommend her! I m still working towards full cure! I m sure I'm getting there! read more

Dr. Nancy has changed my life. I was 100% healthy according to all previous "regular" Doctor visits but I always felt off. My indigestion wasn't quite right and I constantly felt bloated. And then I met dr. Nancy. During our first consultation she listened carefully to how I lived my life day to day:everything from bowel movements to stress levels. Then we took some tests and discovered what foods I was allergic to and what I good bacteria I needed back in my body. It's been six months since I first visited her and not only have I lost 10 lbs but I feel amazing. I no longer feel bloated or puffy and while at times my diet can be tedious I know that I feel best when I stick to it. I couldn't recommend her more. read more

Nancy saved me! After years of going to the doctor to help with an undiagnosable condition, which resulted in multiple and reoccuring viruses, I received a recommendation to go to Nancy. I was skeptical, being the child of two doctors, I always erred on the side of "western medicine," but truly I was desperate! Nancy did a holistic profile, ran a few tests and came up with a treatment plan. I wouldn't call her a miracle worker, but my immune system hasn't been this healthy since I was a teenager, and haven't been sick in months! Thank you Nancy! read more

I have struggled with gut issues for an extended period of time and seen many doctors who could not figure out what was wrong with me. Dr. Mach met me exactly where I was and helped me with not only my gut issues, but my skin issues and energy levels as well. I have never felt so good! Dr. Mach truly listens to her patients and ensures that they are taken care of. I was expecting to have to come back appointment after appointment, but Dr. Mach was able to pinpoint my problems and set me on a treatment plan that truly healed my body.

I've been seeing Dr. Mach for almost a year, and her work has been excellent. She has taken very special care in assessing and treating my issues related to adrenal fatigue. As these types of issues can be very complex and multifaceted, she has been very thorough and precise in making sure that we are addressing them correctly. Dr. Mach offers very personalized care; I would definitely recommend her for any endocrine-related problems, or other issues that could get overlooked or misdiagnosed by conventional medical practitioners. read more

I have been a long time patient of Doctor Mach. Some of the things she has helped me with are adrenal fatigue, nasal congestion and digestion. Without her help I would still have issues with sleeping at night due to congestion, problems with taking a few steps up stairs without breaking a sweat, problems with feeling rested after a good nights sleep and feeling depressed because I did not know what was wrong. I am definitely living a better quality of life due to the remedies she has given me. read more

Dr. Mach is a caring, compassionate and knowledgeable person who takes the time to listen to her patients to determine the best way to get to the root of the ailment. Most western doctors are quick to prescribe medication that treat the symptom but not the cause. I have had hypothyroidism for a while and was sick of taking synthetic thyroid supplements and wanted a more natural treatment. I was referred to Dr. Mach, she spent a good amount of time going over my lifestyle, my diet, exercise habits, etc to determine whether I had too much stress, poor diet or other factors affecting my health. I seem to be doing ok in most areas so we switched my medication to a natural form of thyroid supplement. After 7 months of working with her to figure out my dosage, my latest blood test came back with results within the ideal range. I am less tired, in better moods, sleeping better and happy with how I feel. Even though your insurance may not cover the cost, she is worth it. It will be cheaper in the long run because you are getting to the root of the issue. I am really happy I found Dr. Mach! read more

Dr. Nancy is kind, compassionate and very knowledgeable in the field of alternative medicine. From the moment I walked in her office I noticed the great energy there - which was particularly interesting because I came to her office because my energy levels had been low! Dr. Nancy was very welcoming and we proceeded to go through a lengthy intake session. She was very patient and thorough, wanting to make sure she got a complete 360 degree understanding of my health.  Her bedside manner and temperament were always very calm and reassuring. We ended up doing several tests and, from the results, she came up with a comprehensive analysis and recommendations that have proven very helpful.  I've since visited Dr. Nancy with other issues and she was able to address them quickly since the health history taken during the first visit had been so comprehensive. I highly recommend Dr. Nancy as a great alternative to western medicine! read more

Dr. Mach is so knowledgable! If you are looking for a provider who can get to the bottom of fatigue, indigestion, nagging skin problems, or autoimmunity, she is the right person! Often these symptoms are ignored if they are not severe enough by our medical doctors. Fortunately, with Dr. Mach's expertise and experience you can achieve a better quality of life that is symptom free. I love that she has a scientific approach and warm bedside manner. I highly recommend her! read more

I can't speak praise enough for the care I have received from Dr. Mach. After my primary-care physician diagnosed me with Hashimoto's auto-immune thyroiditis last fall, I tried to undo years of illness by treating myself according to whatever advice I could find, in books or on the web. I was able to make some progress with all of the information I found, but I also pretty quickly became overwhelmed. Realizing that I needed someone to help guide me through recovery, I reached out to Dr. Mach. So glad that I did. Professional and compassionate, Dr. Mach is everything I have ever wanted from a doctor: An experienced and knowledgeable collaborator who listens to my symptoms and responds with a unique solution. After committing to her plan, I've been thrilled to see how much my health has improved. I am looking forward to continued progress under her care. read more

I have been suffering from migraines since a young age, and it has become worse and worse over the last 5 years (almost everyday). I tried everything and went to see so many different doctors who gave me different prescriptions. Nothing was really working so I decided to go to see "holistic" doctors even if I was preferring the more pragmatic/western medicine. When I went to see Doctor Mach, she was very attentive and asked me a lot of questions to really understand where I was in my life in term of health. We decided to do a food allergy test to see if my body was not tolerated certain type of foods that could cause migraines. Well, the results came back and I had to stop sugar and the combination of grains and potatoes. Sugar is in everything so it is a tough one! But she was and is still here all along with the process of adjusting my diet and even if I know it is hard I can see a difference in my health and that is so rewarding! I feel now that I am more in control of my body and I have now a migraine once every 2 weeks (which believe me, it is awesome even if it sounds a lot) and I take less pills! I know that doctor Mach changed my health, so basically my life and without her support I could not have done it! Big Thank you!! read more
