Katie Chambers, PA-C spent her early career in emergency medicine, where she saw the same story play out again and again: heart attack, stroke, kidney disease, diabetes, almost always tracing back to metabolic health that had gone unaddressed for years. That pattern is what pushed her out of the ER and into functional and lifestyle medicine, where she's spent her career since focused on catching problems decades earlier instead of managing them after the damage is done.
Her own experience with infertility deepened that focus. Optimizing her metabolic health, blood sugar, cholesterol, insulin, and muscle mass made a real difference in her fertility outcomes, and it's part of why she brings that same depth to every patient's plan.
Katie founded Waypoint because she believes healthcare has stopped listening to patients, and that people deserve a provider with the time to actually catch what's being missed. She wants her patients living long, capable lives, not managing decline.

I grew up in St. Charles, MO but went to high school at Nerinx Hall in Webster Groves. I wouldn't be a St. Louis native without taking the change to mention where I went to high school.
I completed both my undergraduate and graduate degrees at Butler University in Indianapolis, Indiana. Go Bulldogs!
You'll usually find me cooking, playing with my girls, planning my next girls trip, or cheering on STL City SC with my family.
American Academy of Physician Associates (AAPA) and the Obesity Medicine Association (OMA)
Lifting weights is my go-to, but I've done sprint triathlons and would love to get back to that. I also still play co-ed soccer with my dad, siblings, and husband on weekends.
If I'm being honest... iced matcha lattes. I'm becoming that girl. But truly, if you can't find me, I'm probably out somewhere in St Louis trying a new coffee shop.
Definitely depends on who is asking but my overall go to recommendations (and favorites) are The Nightingale, Where the Crawdads Sing and Fourth Wing.
I'm pretty simple. I love a good show or cuddling up in bed with a book. Although in this early summer season, I love to sit outside as the sun sets, watch the fireflies and catch up with my husband after our girls are asleep.
IEvery Waypoint Medical patient is cared for under the collaborative supervision of Dr. Jay Moore. You won't see him at your visits, he works behind the scenes with me on your care, but his oversight is part of what makes this practice possible.
Dr. Moore earned his MD and completed a double residency in internal medicine and pediatrics at the University of Missouri, then spent years as a community-based primary care physician in the greater St. Louis area. Since then, he's held a range of healthcare leadership roles, hospital administrator, executive at a national health insurance company, chief clinical officer for a healthcare finance startup, and medical director for Walmart Health. Today he runs Nexus Primary Care, a direct primary care practice in St. Louis.
He lives in St. Louis with his wife, his dog, and a growing collection of science fiction books and board games. He also runs Geekway to the West, one of the largest board game conventions in the country.
