As dietitians, we believe personalized nutrition and lifestyle support can improve your quality of life.
We’re a nutrition practice built on getting clear answers, a personalized plan, and the support you need to feel your best.
There’s a better way to do nutrition care, so we built it.
Functional Nutrition Rx was created with a simple goal: to help clients feel their best. Founded by Christina Lombardi, MS, RDN, FMNS, the practice grew from a passion for providing more personalized, in-depth support—so individuals can better understand their bodies and experience meaningful, lasting improvements in their health.
She was frustrated that too many people were leaving appointments with generic advice, a medication to manage symptoms, and zero explanation of why they were feeling the way they were. They weren’t failing their health plans, their health plans were failing them.
So Christina built a group practice where every client gets a registered dietitian nutritionist who takes the time to understand their full health picture. No templates. No one-size-fits-all protocols. Just individualized care, backed by clinical expertise and optional functional testing that goes well beyond the standard.

What “root-cause nutrition care” actually means here
You have the option to dig deeper with testing
Standard bloodwork often misses the picture. That’s why our practice uses advanced functional testing to uncover what’s actually driving your symptoms. When we build your plan, it’s informed by your biology, not just best-practice guidelines.
Your plan is built around your real life
We’re not handing you a meal plan that assumes you have two hours to cook every night and zero food preferences. Your nutrition strategy is designed around your actual schedule, your food culture, your family, your stress level—because a plan you can’t live with isn’t a plan at all.
We treat the whole person, not just the diagnosis
Your gut health affects your hormones. Your hormones affect your mood. Your mood affects what you eat. Everything is connected, and we approach your care that way—looking at the full picture rather than treating each symptom in isolation.
Expert care that’s covered by insurance
We accept most major insurance plans because we believe that access to quality, individualized nutrition care shouldn’t be an expensive privilege. If you’ve been putting off getting help because of cost, this is worth a conversation.
We believe that “evidence-based” and “individualized” aren’t opposites—they should always go hand in hand.
We believe that clients deserve to understand the why behind their symptoms, not just receive instructions. And that feeling better shouldn’t require an impossible overhaul of your entire life.
Whether you’ve been struggling with unresolved symptoms for years or you’re just starting to pay attention to how food affects how you feel, you’re in the right place. We’re not here to judge the diets and programs you’ve tried or the appointments that didn’t help. We’re here to figure out what actually works for you.
Good nutrition care doesn’t have a “type.” We work with clients of all backgrounds, body sizes, ages, gender identities, cultural backgrounds, and abilities—and we take pride in building care that reflects your values, not a one-size-fits-all standard. At Functional Nutrition Rx, you’ll never be made to feel like you’re too much, too complicated, or too far gone.
Every provider at Functional Nutrition Rx is mentored, supported, and held to a consistent standard of clinical excellence, so no matter who you work with, you’re getting the same depth of care.
