in the last weekUpdate Jan 2026Just wanted to say that I've had the opportunity to continue to work with Dr. Finnegan and the team over the years. Most recently they helped set me up with a nutrition plan and supplement regimen to support a high level of physical activity while transitioning to life at 50. Adjusting my macros, and taking on creatine have been just some of the invaluable help I've received!*******Incredible Care, Incredible coaching! As an aging athlete, I've had trouble adapting my nutrition and recovery to support my athletic goals. Over the last few years, I had started to notice my energy dissipating quickly over the course of mountain bike rides that I had tackled much easily in earlier years, and just thought "this is what getting old is".Dr. Finnegan and her team gave me hope by suggesting I just needed to adjust my eating and recovery habits to regain my form -- they analyzed my nutritional deficiencies, and prescribed adjustments to the macro nutrients of my diet, along with post ride recovery support so that I would have the vitality to conquer the long rides that bring me such joy. I'm happy to say I've regained much of what I thought I'd lost with their help. Thank you!

2 weeks agoI’ve read off a lot of great reviews regarding Carolyn’s chiropractic care. But this is not that.Carolyn is a true business woman first; a functional medicine doctor on the side.Her bedside manner could use a good dose of polishing.I sought a functional medicine doctor to address my gut and stress issues stemming from decades-old C-PTSD. From the moment we met, Carolyn went to work on treating these conditions. She provided me with supplement treatment and valuable suggestions, which I followed.Carolyn didn’t stop there. She immediately showed interest in replacing specialists I’ve been working with for years, which was a red flag. I hadn’t made these requests, and her interest was unnerving and aggressive. She was also adding unnecessary supplements to my treatment plan.Carolyn’s website states an option to purchase supplements from other sources than those she prefers. That was appealing to me. What she does not disclose is that she receives a profit off her clients when they make purchases from her preferred supplement provider.Upon learning that Carolyn’s preferred supplement provider allows practitioners to set their own price to charge clients, I questioned her about what percentage, if any, she profits. Her response; a defensive, “I am not legally or ethically required to provide a separate written disclosure regarding practitioner margins on supplements or lab tests. Because supplement purchases are optional and not tied to care, a commission disclosure is not mandated.”Yet her website states:Supplements prescribed by our practitioners as part of a personalized treatment plan are considered medical necessities.So, which is it? Optional or medically necessary?I provide patients with a 10% discount through Fullscript, and the practitioner margin I receive is approximately 25%, which is well below the typical margin received by practitioners. However, the other practitioners do use verbiage which disclose a profit. Recommendations are made based on clinical judgment and patient need, not financial incentive. Thankfully, I did not purchase every supplement added to my plan! In 3 months time, I did purchase $2,781.12 in supplements from which she profited. No transparency required. None provided. Icky. A huge turnoff, learning this from a third party.The last time I met with Carolyn, I reported several personal gains. Yay! The treatment was working! Each one of my gains was met by sadly dismissive remarks; “that’s not enough, you need to do more” - followed by her admission of being a “hard ass”. During that same visit, she admonished the nutritionist she works with for recommending an OTC Collagen/Peptides for me. “I’ll have to speak to her about this” and “you can buy that stuff anywhere”. Followed by…..another supplement addition to my plan which she could profit from! By the way, the nutritionist, Magdalena, is lovely and down to earth.If you’ve read my review this far, I hope you will think very seriously about taking your health concerns to an honest, transparent naturopath with morals (they do exist).

5 months agoI've been working with Dr. Finnegan for the last year and a half for my ulcerative colitis. Her warmth and compassion immediately stood out. She shows up not only as a medical professional but also a coach; helping you understand what's going on and build sustainable habits step by step. Dr. Finnegan clearly has extensive knowledge and experience in functional medicine. And I felt like I could trust her to guide me through this journey from day one.I was in a bad flare up when I had my first consultation. It took about 3 months to see initial improvements and 6 months for major symptoms to resolve - slower than I hoped, but the results feel (hopefully) more sustainable. Because of the holistic approach, I not only see improvements to my gut health, but overall health and energy levels.I’ve also enjoyed working with Magdalena on the nutrition side of things. She’s always encouraging and has a ton of knowledge to share.The investment is significant - while the initial package feels fairly priced, monthly supplements and additional consultations add up quickly. Despite the cost, however, I have no doubt it's been worthwhile for the long-term improvements to my health.

5 months agoI came to Dr. Finnegan with whole body dysregulation. I had fatty live disease, no gallbladder, 6 years of IVF medications, treatments and failures, extreme fatigue, brain fog, nausea, loss of appetite and weight loss, migraines, hormonal imbalances and unexplained chronic body pain that conventional doctors could not identify despite MRI's, CT scans and "normal" labs. It is through my work with her over the course of the past year that I identified several root cause issues for most of these symptoms and through healing my gut, liver, hormones and nervous system I am finally seeing the light at the end of the tunnel and feeling more and more like myself.I am grateful for her kind and compassionate approach to this journey I have found myself on and for answering all my questions with a wisdom and knowledge that you just can't find with a traditional practitioner. I am incredibly grateful I made my way to Dr. Finnegan's office and will continue to sing her praises as an incredible tool to have in your tool belt if you are navigating any issues that are not acute. Learning how to properly nourish your body and feed it the nutrients and minerals it needs to thrive is a gift I'm so grateful to have found with Dr. Finnegan and her team. She is a gem!

8 months agoI have had digestive issues my entire life. Traditional doctor’s helped with my acute symptoms and a diagnosis of IBS but nothing for the root causes of my condition. By the time I met with Dr. Caroline Finnegan in June of 2023 I was in a lot of pain, completely exhausted and unable to digest most foods. Functional medicine takes patience, dedication and a lot of trust to succeed but I can tell you that Dr. Finnegan and her nutritionist Magdalena Calabrese at Core Wellness Functional Medicine are wise women with a depth of knowledge, personal experience and a genuine desire to create a path for long term healing. The office manager Amanda Rulong rounds out the team by keeping things running smooth. I felt heard, seen and understood. The tests are expensive, the dietary requests are initially alarming, not all of the treatments bring immediate relief – it is a science and every body is different - but within a few months it was determined that I was not making digestive enzymes and that I was both gluten and lactose intolerant. By diligently following the treatment plans of supplements, diet and lifestyle changes I began to slowly heal. It has been two years now and I am feeling better than I have in years. Not only is IBS a part of my past, I also have way less anxiety and depression. Even though I thought I followed a sensible diet, the food I was eating was harming me and no traditional doctor was ever interested in helping me figure this out.
