  • “Stephanie was everything I could have asked for and more in a nutrition partner. I’ve struggled with acne for years and after researching and trying everything I could get my hands on, I was still not happy with where my skin was at. After developing stomach issues on top of the acne, I knew it was time to get professional help. Stephanie provided me a partnership that focused on mainly diet as a tool to heal stomach issues which results in the healing of skin. She gave me amazing resources on recipes, tools to reduce anxiety, a specific supplement plan and more. She is so kind, attentive, knowledgable, caring, and responsive. I always felt like I was in the best hands with her. I started feeling better almost immediately and now three months later my skin and stomach issues have resolved!!!"

  • "When I first reached out to Stephanie, I was struggling with the daily symptoms of Hashimoto's Disease. These symptoms were taking a toll on my quality of life. One of the standout aspects of my experience with Stephanie was her ability to provide me with customized supplements tailored to address my energy levels, digestion, and sleep patterns. It was evident that her recommendations were rooted in a deep understanding of nutritional science and a genuine desire to help me thrive. Her meal plans were a game-changer. She crafted meal recipes that not only met my dietary requirements but also worked seamlessly with my lifestyle. If I ever needed a new meal, she always had one available. ... 100000000% recommend!!!"

  • "I have been wanting to meet someone like Stephanie for years! She is the reason I feel more confident with knowing how to navigate my health as a young adult. I now know exactly what to put into my body and what to get at the grocery store. I enjoyed getting my bloodwork analyzed where Stephanie was able to explain and break concepts down in a way that I could understand. She knew exactly what my body needed. She is also very sweet, quick to respond, and has been flexible with my schedule. I am grateful I invested in my health by investing in Stephanie. She helped me create healthy habits that I can keep for the rest of my life. Thank you, Stephanie :)"

  • "Stephanie is TRULY a life saver! I was suffering from constant nausea after meals, low energy, terrible sleep, painful periods, mood swings & headaches. My general practitioner did nothing to help with any of these things. Stephanie’s 8 week program helped me by changing my diet, getting on the right supplements & creating healthier habits in my day to day life. She is extremely knowledgeable & professional & also a very kind person. I love that she specializes in women’s health & balancing hormones. I’m so glad I found her & can honestly say she changed my life."

  • "Stephanie is such an amazing human and so knowledgable! She kindly listened to all of the health challenges I was facing and then from there was extremely thorough with her analysis and next steps. I have tested the steps Stephanie gave me and feel so much more energy, better digestion and I truly feel that I am in good hands!! All traditional medicine tests say I am fine, but I still have had lack of energy and poor digestion. Thanks to Stephanie's help I am seeing huge improvements in both areas! I would highly recommend you using Stephanie!"

  • "Stephanie is amazing! She is so knowledgable about nutrition and how things affect your body. She is very supportive and encouraging which made a huge impact for me during my process of developing a better relationship with food and improving my gut health. Her philosophy is great as it is not based on restriction or avoiding foods but rather learning how you can find that balance and still enjoy the things you love. I recommend her program to anyone that is interested in getting some more guidance into their nutritional health."

  • "Oh, let me count the ways that I adore Stephanie... I had the pleasure of working with Stephanie over the course of a year. I came to her with a whole assortment of health challenges that had been ongoing for 6 months at that point. While my health issues were not pleasant, my journey with Stephanie Killen was the absolutely best thing that could have happened to me. First, she listened to me and heard my concerns. Then, she took me down a path of gradual steps to recovery, layering in new levels when appropriate. Then, she listened to me a ton more and helped to recommend adjustments to my protocol to accommodate my ever-changing body. I emphasize that Stephanie listens, because we all want to be heard, right? Especially so in matters of our health. But how many of us have visited the doctor and left feeling unheard and therefore completely defeated? I know I have, countless times. As a Nutritional Therapist, Stephanie truly cares. She will listen to you and she will be your cheerleader the whole way through. ..."

She not only has been able to help and advise me through some of my darkest times dealing with a chronic illness, but she has also helped me balance my hormones and feel truly amazing! I can’t recommend her services enough! She is a wonderful communicator and really takes the time to listen and figure out her clients needs, and the root of the problem. I don’t know what I would do without her!"

  • "I found Stephanie after being utterly let down by western medicine practitioners after trying to get relief for some digestive issues I had struggled with for over a year. After seeing numerous doctors through my insurance who made me feel both insulted (one doctor said that my bloating was either menstrual or due to eating an abundance of nuts- neither were the case in the slightest) and not taken seriously with what i'd been experiencing, I was growing depressed and in fear whenever I ate anything. I even went so far as to have a colonoscopy/endoscopy at age 27! The results were that I had some inflammation in my esophagus and I was put on an over the counter acid reducer, which only made my symptoms of bloating, fatigue and rashes even worse! It was so bad that if I ate certain things I would fall asleep in the middle of the day due to my body just shutting down, very scary for me as a busy and generally healthy person in my mid twenties. ..."

  • "Steph is seriously my all times favorite nutritionist who is so knowledgeable and extremely communicative . I mean she was there to pick up the phone at all times and so patient with all my questions. While doing a 30 day reset cleanse I learned a ton about how my body reacts to different foods while working with steph as well as picked up on healthier food alternatives that taste just as great as the unhealthy ones. Even better actually! I noticed My face cleared up, my body was toned , my energy was high and my mind was clear. Steph gave me a new perspective with how to feed my body and make better choices. I highly recommend her to be your nutritionist, She’s straight up amazing ! The amount of awareness and knowledge I got from her will last me a lifetime and that is so worth it! Thank you, steph for improving my life!"

The recipes (easy & delicious to make), and the encouragement (Stephanie was always there & so deeply knowledgeable) make this program above & beyond top notch! HIGHLY recommend!!!"

  • "I started to work with Stephanie to help me with my sluggish thyroid, weight loss, and overall hormone balance. We worked together for 8 weeks and during that time she helped me create a more balanced diet for myself that gave me more energy and improved my digestion. The supplements she suggested really helped me balance my hormones and I saw such great improvement in just 8 weeks. I am so glad I decided to work with her and I highly recommend her to anyone looking for a holistic nutritionist!"

  • "I have worked with Stephanie since March of 2023 for two major gut related issues and let me just say it has changed my life. First of all, just finding out why I was experiencing bloating that made me look 5 months pregnant with acne and other gastrointestinal issues was such a relief. Stephanie created a plan with food modifications and supplements to help get rid of my GI issues along with encouraging exercise and other healthy tips. Let me just say that the anti-fungal diet is HARD but the results and feelings when you commit are worth it. Trust me- if I go back to my pre-Stephanie eating I notice instantly that my body does not appreciate those choices. I needed A LOT of hand-holding and to be honest it was a roller coaster for me but the amount of information I learned, the routine I got into, the yummy recipes I made were all Stephanie's doing and I am so grateful. I am still working on changing my food choices to support what I know my body craves and deserves but it is a lifestyle shift and she has helped me accept that. I 100% recommend investing in your health and letting Stephanie set you on a really life changing path."
