Posted on Sabrina ToomeyDecember 16, 2025Trustindex verifies that the original source of the review is Google. Renew Integrative Health has truly been life-changing for me. Andrea has been nothing short of amazing in helping me manage my fibromyalgia, hypothyroidism, and a very low immune system. Before working with her, I was in a fibromyalgia flare more than half the year. After three years under her care, flares are less than 10% of the time — something traditional doctors could not accomplish in over 17 years. For a few years I also used to be constantly sick — colds, bronchitis, you name it. That cycle is finally broken. Everyone’s journey is different, but if you stick with Andrea and follow her treatment plan, healing is possible. I’m beyond grateful for her knowledge, care, and commitment to getting to the root cause — not just masking symptoms. Highly recommend 💜Posted on Kregg SchaenNovember 17, 2025Trustindex verifies that the original source of the review is Google. I’ve been seeing Andrea for awhile now and she is fantastic. She’s compassionate, and truly cares about getting to the root cause of whatever issue you are coming to see her for. She does a great job of researching symptoms/issues and coming up with solutions based on her expertise, research, and the network of other professionals she works with to solve people’s complex issues. Not only that, but she does a fantastic job managing the human side of these issues and you can tell she genuinely cares about her patients. I was skeptical of the holistic medicine approach when we started, and was forthcoming with Andrea about my concerns. I can happily say she was understanding of them and has proved those concerns I had to be wrong. I can’t recommend her or her practice enough!Posted on Erin GoodwinAugust 12, 2025Trustindex verifies that the original source of the review is Google. We are thankful to have found Andrea and Renew Integrative Health. After a year+ of visits with specialty doctors, multiple medicines and treatments, Andrea was the only provider able to actually pinpoint what was happening with our daughter. She took her time to thoroughly assess our daughter and all of her symptoms, she walked us through each step of treatment with kindness and care and she is feeling better than she has in years!Posted on CarlaJuly 26, 2025Trustindex verifies that the original source of the review is Google. Andrea is truly outstanding. She went above and beyond to uncover the root of my health concerns and provided thoughtful, thorough support throughout the process. If you're searching for real answers and meaningful results, Andrea is the person you want on your side.Posted on wesley soliwodaJune 16, 2025Trustindex verifies that the original source of the review is Google. So glad I found Andrea several years ago. She's helped me with weight control, general wellness and specific health goals, Highly recommend.Posted on Tim FordMay 19, 2025Trustindex verifies that the original source of the review is Google. Renew Integrated Health is a fantastic place to get (or learn how) to get your body at optimum capacity. Andrea takes time to listen to you & offers suggestions while ensuring you understand what's being proposed & doesn't shy away from questions, even researching if need be, & getting back with you to discuss her findings. If you're ready to take control of your body & health with a practice that uses both integrative/functional and conventional medicine, please don't hesitate to contact Renew Integrative Health--your overall physiology will thank you (by showing how great you can feel!).Posted on Chris CMarch 21, 2025Trustindex verifies that the original source of the review is Google. Andrea has been an amazing help to me. When no one could or would help me, she persisted and helped get me to the point where I can do things again. She is very genuine and always well meaning. Her office manager Teren is amazing as well , very pleasant. They are a great team! I would recommend Andrea and her office to anybody struggling with an illness.Posted on Beverly CasebereMarch 20, 2025Trustindex verifies that the original source of the review is Google. I began with Renew in January 2025. It has given me a totally different perspective on health care. Andrea doesn't treat symptoms, she finds the cause of health issues. I've never found a doctor who has spent as much time with me, done the extensive testing, as well as gathering information, so she can do her best to keep me healthy, and help me be able to have a good quality of life. She truly cares about her patients putting in the time and effort to assure she is doing her very best for each individual. She is warm, friendly, and understanding making me comfortable and at ease. Her office is a pleasant space set up with technology to keep tasks easy and convenient to complete. She also has a top notch assistant, very knowledgeable about all aspects of her business, ready to assist at any given time. I feel very fortunate to have discovered this new way of taking care of myself.Posted on Chandra ShermanMarch 2, 2025Trustindex verifies that the original source of the review is Google. I discovered Andrea in a desperate search to find answers after many years of being sick. I have worked with many functional medicine doctors and naturopaths in the past and her intake process and initial interview was more thorough than I have ever experienced. Andrea did a physical exam and found an issue even my pulmonologist had missed. By ordering a chest x-ray and calling me late Friday night with the results, she quite literally saved my life. Once I received my diagnosis of stage 4 Breast Cancer, she has been incredibly kind and supportive. Although I am receiving my oncology treatment more than an hour away, it has been so amazing to be able to access high-dose vitamin C IV treatments in her office. As well as a mild hyperbaric chamber when I’m ready for that stage of healing. She is willing and happy to coordinate with my other practitioners. I feel so safe knowing that she orders her raw materials from a compounding pharmacy, stores them correctly and is completely transparent in what I am actually receiving in my IV. Her office is warm, comfortable and beautifully maintained. Her portal is easy to use to contact both her and her office staff. I have many health appointments each week and Renew Integrative Health is the only one I actually look forward to. Regardless of what you are struggling with, if you aren’t getting answers elsewhere and you don’t feel your best, please do yourself the favor of working with Andrea. Your future self will thank you.Posted on Valerie DeLisleAugust 19, 2024Trustindex verifies that the original source of the review is Google. I made my first appt with Andrea after years of receiving no help from a long list of Doctors. She is the only one who fully listened to all of my symptom complaints and ran tests that no one else would. I got answers I never would have otherwise gotten and understood. I have definitely seen improvement and, when I follow her instructions, I feel so much better. Autoimmune illness is so mis-understood and she is the first and only to understand me and get me the answers I need!Load more

Conditions That We Treat
Discover the wide range of conditions we address as your dedicated functional medicine provider. We focus on root causes to promote lasting health and well-being.
Menopause
Menopause naturally occurs in middle aged women when the ovaries begin making less estrogen and progesterone which leads to a permanent end of menstruation and fertility. The child rearing responsibilities are gone and a perfect time to focus on yourself.
Fibromyalgia & Chronic Fatigue Syndrome
Chronic Fatigue Syndrome (CFS) is a complex disorder defined as fatigue lasting longer than six months and cannot be explained by an underlying health condition nor alleviated with rest.
Joint Pain
As of 2021, 24% of adults have been diagnosed with Arthritis making it the leading cause of disability in the United states. This condition occurs as inflammation increases, the fluid in the joint decreases and the cartilage between bones begins to break down.
Hashimoto’s
Hashimoto’s thyroiditis is an autoimmune disease where the immune system mounts an attack on the thyroid gland resulting in a slow destruction of the gland over time.
