Rachel’s Story

I have been practicing as a functional dietitian for 8 years, with 10 years of total clinical experience, and the path that brought me here was anything but a straight line. My own struggles with debilitating allergies, endometriosis, and digestive concerns pushed me to look beyond what conventional medicine was offering. I kept being told my symptoms were normal, and I knew they weren't. That experience of finally addressing the underlying reasons behind what I was feeling, rather than just managing it, is what drives everything I do with clients today.

I specialize in autoimmunity, women's health and hormonal concerns including endometriosis, unexplained infertility, and PMDD, and digestive distress across the full spectrum including IBS, IBD, constipation, diarrhea, gas, and bloating. I also work extensively with histamine-related issues and MCAS, skin conditions like acne, eczema, and rosacea, and fertility optimization including sperm quality. These are conditions that often get dismissed or oversimplified, and I think the people navigating them deserve a practitioner who will actually dig in.

Nicole Antes, MS, RDN, FHP-C

I am a registered dietitian with a strong background in autoimmune care. I am passionate about using holistic and mindful approaches to help people improve their health and heal their bodies through nutrition. My journey with chronic illness has been challenging and non-linear, like many others. Through this, I’ve learned the integral role of nutrition and lifestyle changes in managing and reversing chronic conditions. When conventional answers failed me, I discovered functional medicine, where I now focus on understanding the root causes of my clients' health concerns. This journey has given me a deep empathy for those who feel unheard and unsupported, fueling my drive to provide thoughtful, individualized care.

Nicole’s Story

I am a Functional Dietitian with 4 years of clinical experience who takes a whole body, root cause approach to health and healing. My passion for functional nutrition was born from my own health journey. After being diagnosed with PMOS in 2021 and feeling like I wasn’t being fully heard or supported by conventional care, I began exploring functional medicine and discovered a new way of looking at health. Through this approach, I was able to significantly transform my own health and quality of life.

My journey has continued to evolve, including a recent diagnosis of endometriosis, giving me an even deeper understanding of what it means to navigate chronic symptoms and advocate for your health. I use both clinical experience and personal perspective to help clients connect the dots between their symptoms and uncover the underlying factors affecting their health.

I especially love working with clients navigating hormonal imbalances like PMOS and endometriosis, gut dysfunction, and autoimmunity, helping them feel heard, empowered, and confident in their health journey.

Julie’s Story

I’ve been practicing as a functional medicine dietitian for eight years. I was drawn to this work because I know what it feels like to go from feeling completely healthy to suddenly feeling like your body is betraying you, without getting clear answers from the medical system. I know how exhausting it can be to bounce from specialist to specialist, and how scary it can feel to put your trust in someone when it comes to your health.

Because of that experience, I really understand how vulnerable it can feel to put your health and your body in someone else’s hands. My goal as a practitioner is to make sure my clients feel heard, supported, and confident that we’re looking at the whole picture rather than just treating individual symptoms.

I specialize in complex digestive concerns like IBS and IBD, hormonal conditions including PCOS, endometriosis, menopause, and fertility, as well as autoimmune and inflammatory conditions, skin concerns, and MCAS or histamine-related issues.
