Anya is very knowledgeable, organized and understands everything I would explain to her. She absolutely fixed my gut through testing, supplements , and helped me maintain a balanced diet. I would recommend working with her 100%!! Im so happy with my progress and outcome(:

Anya is great! She actually listens to the issues you are having and works with you to find the root cause. Highly recommend!

Anya is an excellent functional medicine practitioner. She is incredibly intelligent, thoughtful, and has a real foundation of knowledge through years of training, study and research. I am a therapist who has referred clients to Anya before and wouldn't hesitate to do so in the future. I would trust that any client of mine that I referred to Anya would be in the hands of a compassionate, thoughtful provider who will do her best to help them get to the root cause of their issues in a holistic, mindful way.

I worked with Anya for 6 months and saw major improvements! My biggest issue was hormonal acne, which completely cleared. My gut health, energy and sleep also improved. Anya takes a holistic approach and looks at all of my symptoms & behaviors to get to the root cause. I wouldn’t hesitate to refer friends and family to her, she is well worth it.

I have been suffering with a bad gut for decades and had gone to a multitude of doctors. No one could find the root of the problem. I could never go out to eat without worrying. Anya Rosen did a battery of tests and discovered my issue. She was able to get rid of the bad bacteria and build my gut up again. I'm pleased to say that my bloating is gone and I can now eat meals without a worry. Such a relief. Thank you Anya!

My experience working with Anya was wonderful. Due to her support and recommendations, in just a few months, my lifestyle has shifted so much! I now go to the gym regularly, and my diet is the healthiest it has ever been. I've lost several pounds, and feel great. Her interpretation of my DUTCH test results was very thorough, and going through this process was incredibly helpful. Anya helped me with my insomnia issue by recommending the best supplements for my particular situation. She was always ready to answer any questions I had, and gave me excellent tips, tools, and supplements to set me up for longterm health success.I'm extremely grateful for my experience with Anya, and I highly recommend her.

Anya has been such a light in my life these past several months. I was struggling with digestive issues and navigating an endometriosis diagnosis and Anya was able to guide me in the right direction! She provided me with information on what supplements to take, gave me food/recipe recommendations to fit within what I was already doing, and overall holistic wellness advice. I truly wouldn't be in a better place right now if it wasn't for her. She knows what she is talking about and I couldn't recommend her more!

One of the best decisions I’ve made as a therapist has been approaching my own health with a holistic route. Having Anya guide me through this journey has been the most helpful experiences. She’s responsive knowledgeable and listens to all my concerns. I’ve seen such a huge change in my health it’s been incredible. You won’t regret working with her!!!

Working with Anya has been nothing short of life-changing. She’s incredibly knowledgeable, compassionate, and truly takes the time to understand your individual needs rather than offering a cookie-cutter approach. Her depth of expertise in functional health, hormones, and gut healing is unmatched and what I appreciate most is how she connects everything back to the bigger picture of your overall well-being. Every recommendation she’s made has been intentional and effective, and I’ve seen real results both physically and mentally. You can tell she genuinely cares about her clients and wants to see them thrive. I can’t recommend Anya enough — if you’re serious about transforming your health, she’s the one to work with.

I came to Anya this past year when I started having awful acne and hormonal issues. My skin was so inflamed and painful. I had tried everything I could think of on my own and had been considering seeing a functional medicine practitioner for a while. I was seeing no results trying to self diagnose myself for months. I was getting married soon and didn’t want to feel insecure on the most important day. I wanted to be confident and present. After my first initial call with Anya I felt confident that she would give me all the answers and get to the root cause of my acne. She had me do some functional testing and got me on a personalized protocol and within a month I already noticed a huge difference in my skin as well as my gut! She also gave me a skin care regime to follow which was so amazing to have both sides of treatment (internal & external). She was great at answering any questions I had along the way and always kept me looking at the bigger picture holistically. No quick fixes or unrealistic recommendations. After following her protocol the majority of my symptoms disappeared and my skin is now the best it has ever looked! And I have no scaring thank the Lord!! Anya is the reason I felt confident on my wedding day and I couldn’t recommend her enough weather you have health problems or skin issues (acne, eczema, etc.) I plan on getting re testing done with her in the near future and will continue to use her for anything down the road. She is so knowledgeable and I trust her to help fix any symptoms I might have! She’s amazing!! I attached some photos of my skin before & after Anya!
