My hubby (age close to 60) would come from work and just hit the couch or just go to sleep early. Then after we invested in the testosterone pellets his energy and mood improved 110%. No amount of supplements can do that amount of change in a short amount of time!!! I love Steph as well.
I honestly don’t understand how this clinic has positive reviews. I really regret investing the time and money here—it was way beyond unworth it. Before signing up, I was told they had a 95% success rate, which gave me confidence to move forward. Unfortunately, after finishing the full four-month program, I left feeling about the same as when I started. The only improvement I noticed was finally being able to have regular BMs—which, while helpful, was far from the overall progress I was expecting to receive. I did both a GI Map and a SIBO test, but it seems as if their treatment approach wasn’t fully customized to me. It honestly felt standardized, like they were following a set formula — like they have their “go-to” supplements and protocols, and if those don’t work, there isn’t much flexibility or exploration beyond that. Around the halfway point, my appointments with Dr. Thomas started to feel repetitive and unproductive. I’d share the same ongoing symptoms — bloating, gas, puffiness, reflux, hair loss, etc — and we’d make minor tweaks that never helped. I also told her that the Low FODMAP diet wasn’t working for me and asked for something more specific, but I was told to just stick with it. It was frustrating to keep following something that clearly wasn’t making a difference for me. To be fair, both Dr. Thomas and the staff were always friendly and polite, but it was clear they only knew what they knew — and there wasn’t much room for problem-solving outside their standard approach. What really disappointed me was their policy on refunds. Even after it became obvious that we weren’t making progress, they refused to refund the unused sessions. Those last appointments felt like a complete waste of time because there was no new direction to take. Now, I’m working with yet another specialist who immediately found a few key things missing from my previous protocol — things that likely would’ve made a real difference with my methane-dominant SIBO. It’s frustrating to realize how much time and money I wasted here. I genuinely wish I’d chosen differently. This experience was deeply disappointing and not one I would recommend to others. Anyone reading this, please save your money and spend elsewhere.
Dr. Stephanie Thomas was God sent for me! She is very caring and has great knowledge of natural healing and very affordable with optional payment plans! She really spent time with me and my Husband listening to concers and symptoms asking a lot of questions to figure out the root cause unlike traditional doctors. And once we found it, she gave me an action plan to follow, for 3 months. And I've seen great improvement in my health. Now that I'm not with her anymore, I feel confident that I can continue what she had taught me about my body to stay on the naturalpath to continue healing. Her staff Rosalind and Hannah are genuinely kind, caring, supportive and helpful answering questions between my visits. 💯 % recommend her!🤗
My experience with Stephanie Thomas and her team has been nothing but great. Stephanie Thomas is personable and knowledgeable. She answers any and all of my questions that I have. Her team is friendly and very efficient as well.
I started seeing Stephanie Thomas in July. I had severe gut problems along with bloating that made me look 5 months pregnant with even a small snack. No matter what I ate I was bloated. She tested my gut microbiome and hormones. She informed me I have SIBO (small intestinal bacteria overgrowth) and candida overgrowth (yeast) in my gut along with very high estrogen levels with zero progesterone. My other symptoms ranged from exhaustion, insomnia, rage, irritability, and extreme sadness (high estrogen). The last few months she put me on a diet with no sugar, no gluten, no carbs(besides few fruits and veggies) and no dairy. I was also put on hormone supplements, oregano, probiotics, and digestive enzymes. Four months later, my hormones leveled out to normal. My body produces progesterone (means I can get pregnant now) and all of my gut issues went away. I lost approximately 15lbs in a short time frame; I was holding so much fat from candida overgrowth. I’m able to get a full night of sleep, have more energy throughout the day, mood is normal and my bloating went away. I highly recommend Stephanie Thomas as a naturopath doctor; she fixed all my issues and was there every step of the way. She’s very knowledgeable, caring and very sweet. I’m thankful I was able to find her and forever grateful she healed me. Photo attached was me bloated without pushing out… other is me now not even sucking in; no bloating!
