Client testimonials

"I started seeing Karyn two years ago, and she has been a TREMENDOUS help on my healthcare journey. I started experiencing gastrointestinal issues 3 years ago that caused me intense suffering on a daily basis and controlled much of my life. I have been to countless doctors and healthcare professionals and tried a myriad of treatments. As a young woman, it was very hard to find a healthcare professional who would listen to my concerns, genuinely care about the impact my symptoms had on my daily life, and do everything they could to help me. I finally found that in Karyn. She asks so many great questions to make sure she deeply understands each piece of the whole picture. I appreciate how she always explains in great detail the science and methods behind her suggestions so I know it's backed by evidence and isn't just some random suggestion that will be a waste of my time. She is realistic and emphasizes creating a plan that will be sustainable long-term depending on my lifestyle. She is not content just being good at her job, she is constantly searching for more information and learning the latest findings in the industry, which means her advice is always based on the latest information. She has a holistic approach and doesn't just focus on what you're eating, but on your stress, sleep, activities, medications, medical history, etc. She helped me check off so many items on my list and ultimately led me to finding the correct diagnosis and treatment for my symptoms. I am now symptom-free and I never thought this day would come. I also know so much more about my body and nutrition specific to ME. She truly goes above and beyond. I HIGHLY recommend Karyn to anyone who is really wanting to dive deep into their nutritional journey, experiencing complex or undiagnosed nutritional issues, or really wants to take the next step for their health."

Karyn is a delight to work with and has helped guide me back to health in a hugely impactful way. I came to Karyn with a slew of frustrations and questions around body inflammation, chronic headaches & dizziness, brain fog and fatigue, food sensitivities, the list goes on. From her deep listening skills to understand my needs/symptoms, coupled with her functional medicine expertise to quickly hone in and prioritize a pathway forward, to the celebration of incremental wins along the way, Karyn has been the best partner in my health journey. I can't recommend her enough!

Karyn is a nutritionist at The Noe Valley Clinic and Metropolitan Medical Group with all sorts of fancy credentials. In addition to being deeply knowledgeable, she's extremely friendly and easy to connect with. She's got all sorts of practical info and tools to get you eating and feeling better. She's also a fantastic role model and couldn't be seemingly happier, prettier, slimmer or more fashionable!

I feel so lucky to have met Karyn – she’s articulate, thorough, a good listener, and really responsive.It's been a real eye-opener to see how oncologists to RNs to general practitioners all absolutely avoid conversations about nutrition and overall systemic influences. Karyn helped validate my questions and already have given me so much good info.
Mathew, C.

Karyn has been fundamental in helping me change my views on nutrition with compassion and grace. Her "filter" on whole foods has a been great tool when I've been looking at recipes or browsing menus at restaurants. Eating has long been an area of my life that I have struggled to navigate and I'm pretty positive that I wouldn't have been able to make this kind of progress without Karyn. Her advice is a wonderful gift to me and all my coworkers at my office. Be sure to ask her about her recipes they are delicious and simple!
Kate D.

Karyn is the nutritionist who helped me to improve image about nutrition.My 2 previous nutritionists tried to "fix me" with corporate-made supplements while Karyn was much more thorough in her approach. l appreciate mostly her holistic and precise assessment that gave my issue much more clarity, room for exploration and finding the closest cause of the problem that previous two 'lazy' nutritionists (you have fast metabolism, you can't do much about it) could not address. I truly, highly and deeply recommend Karyn.

Karyn and I connected when I was trying to understand what was happening to my body when i turned 30 (and gained 20 pounds in 2 months!). Karyn has made such a great impact in my life that I feel compelled to tell the world about her. I did the elimination diet, wrote journals, tested many dietary supplements, and simply consulted with her on food/health choices. Her approach to nutrition, daily adapted/healthy routines, and personable services have made me a new person. In addition, the ramifications of her suggestions to my life were also great (four years into this, i crossfit now, and I am on a Paleo life style). If it was not to Karyn to jump start my health kick in such a positive way, I would not be where I am today. She also allowed my husband to participate during our appointments, making it a family journey. I SUPER recommend Karyn, and I wish I had not moved away from California....otherwise I would continue seeing her.

After a visit to my general doctor, it turned out that my triglycerides were sky high, specially for someone my age and body build. My doctor recommend Karyn. I was extremely hesitant to go knowing that high cholesterol can only mean 1 thing, a new diet. When I finally made my way to the clinic, Karyn received me very cheerfully and with an extremely positive attitude. She was very attentive, informative and sensitive to my particular situation. She proceeded to share a ton of recipes with me after letting me know the things I should not consume. As she said, it's not that you can't eat burgers or pizza, but it might be better for you if you replace certain foods with these. This positive approach made me change my perspective, diet and lifestyle completely. Not only did I started to eat healthier, I started absolutely loving all the new things I eat. I used to despise oatmeal and now I eat it almost everyday thanks to a few of her recommendations. I recently went back to the clinic to see how my cholesterol was doing, and not only did it DRAMATICALLY drop, now it's excellent. The biggest surprise is that it only took about 5 months. My cholesterol was so high that a friend of mine back home who is a doctor was considering prescribing medication for it. Karyn taught me that being conscious about what you eat is all you really need. I wish I could give her 10 stars :)

Karyn’s follow-up e-mail may be one of the most helpful set of emails I’ve ever received from a doctor’s office :).
