Hi, I'm Lyndsy, founder of FNDATN. I know what it feels like to be let down by conventional medicine and lost in a maze of symptoms without answers.

As a driven athlete and Emergency Department NP, I was shocked when I started experiencing fatigue, weight gain, brain fog, and new gut issues despite my rigorous CrossFit routine. I was doing everything "right," but my body felt like it was falling apart. I was frustrated, disheartened and knew something had to change.

When my colleagues' solutions—more exercise, less food, and a prescription for thyroid meds and antidepressants—didn't cut it, I realized I needed to dig deeper. That led me to explore Functional Medicine, which sparked my journey back to true health. I found the root causes of my health struggles and began to heal in a way that felt empowering and right.

Now, I use that experience every day to help my patients avoid the pitfalls I encountered, blending the best of Western Medicine with the wisdom of Functional and Anti-Aging care. At Foundation, we're all about getting to the bottom of every health issue and creating a truly personalized path to your optimal health.

I spent years going to “conventional” doctors only to be dismissed, over prescribed, rushed through and basically ignored. I feel so fortunate to have found Lyndsy and her practice because she spends time really getting to know her patients, listening to their needs and then creates actual change.

"The information I’ve learned is invaluable and most importantly I feel so much better both physically and mentally."
