FNDATN Functional Medicine & Aesthetics, a functional medicine clinic in Boise, specializes in hormone optimization and bioidentical hormone replacement therapy alongside comprehensive assessments of thyroid function and gut health. The practice takes an individualized approach, beginning with detailed lab work to identify underlying imbalances rather than treating symptoms in isolation. Treatment protocols address hormone-related decline, metabolic dysfunction, and digestive dysfunction as interconnected aspects of longevity and whole-body health. Patients receive ongoing monitoring as protocols are adjusted, and the clinic emphasizes coordination with existing providers where appropriate. The practice positions itself as an alternative entry point for patients seeking functional-medicine workups before pursuing more invasive interventions.

Where to begin!
I'm an Ultra Marathon Athlete and just started running 100 miles races in 2023. I'm a friend of Lyndsy's through her fiancé Rob, we met a few years ago when her and Rob came through Casper on a trip. I was up doing some branding photos for her business in 2024 helping Rob out, and while I was up there she offered to sponsor me as a FNDATN Athlete for my Wyoming Range 100 race. Blown away by the offer and her generosity, of course I said yes, it seemed too good to be true! We dove right into my health history, current diet, any struggles I was experiencing, goals, and did an extensive blood panel to find any deficiencies in my overall health and micro nutrition. After receiving all the information back from my blood panels she needed, we did a couple teleconference calls to first go over my results, and then we went over a personalized curated supplement plan to help me perform my best. I can honestly say having trained and ran my last two 100 mile races under her wing and guidance, I have felt a HUGE difference and improvement, not only in my gut health, but also performance during my trainings AND racing. In addition to micro nutrition and gut health, she has also helped me with peptides to assist in even faster recovery.
I can't thank her enough for sharing her passion and gift of medical knowledge and gut health with me and this world, it has made such a huge difference in my life. Once I recover from this last race, I look forward to working with her on a complete gut health panel to even better my knowledge of what my body needs to perform even better!
Thank you from the bottom of my Lyndsy!

Lyndsy has been nothing but amazing during this entire process of deep diving into the root causes of my various symptoms. She is extremely knowledgeable, compassionate, and validates the symptoms you are experiencing are not just “stress related” as other providers have led one to believe. Her thoroughness is beyond exceptional and I feel the most confident in her care. I would recommend Lyndsy 100% to anyone looking for a provider that will impact their lives and health in such a positive way!

Lyndsy and the team at Foundation have been amazing to work with. After years of trying to figure out why my body didn’t feel good, I came to Lyndsy and finally felt listened to and understood. I felt as though my symptoms were addressed as a whole, instead of individually. She is very knowledgeable and has helped me get on the path to healing my gut. I would highly recommend to anyone needing more individualized care!

From the very beginning, working with Lyndsy felt like family. So easy, natural, and safe to talk to her. Lyndsy and her team are truly top tier. She really knows her stuff, not just clinically but in the way she listens and holds space. Working with her feels complete, like everything that needs to be brought to the table actually is, and nothing feels rushed or overlooked.
I’m excited to be on this path of healing with her, especially as we begin checking hormones and addressing things at the root. I’m seriously grateful to be working with her!

I can’t recommend FNDATN Functional Medicine enough!!!
Working with Lyndsy has been such an eye-opening and empowering experience. I came to her feeling completely stuck with my night time routine and sleep in general. I was on a hamster wheel of things on what to do and how to STAY asleep! I was consistently frustrated, tired, and not getting answers anywhere else. She took the time to actually listen and dig into the root of what was going on instead of just treating symptoms.
Her approach is both scientific and compassionate, and I finally feel like I understand what’s happening with my body. Not to mention, she is SO compassionate and listens to me every second of our call! The testing, the explanations, and the ongoing support have all been incredible. I’m so grateful to have found someone who truly cares and knows her stuff.
If you’re struggling with hormones, fatigue, or just not feeling like yourself, I can’t recommend Lyndsy and the team at FNDATN enough. They genuinely change lives.
