Katherine Jeffers, MS, RD, LD

Hi, I’m Katherine!

Integrative and functional dietitian

I’m an integrative and functional registered dietitian who helps clients heal from the inside out. I use a holistic approach that blends functional nutrition, lifestyle support, and root-cause investigation. I believe that eating well should support your life and that wellness can be both effective and enjoyable.

My own health journey deeply shapes my work. For years, I struggled with persistent gut issues and unexplained symptoms.

I saw multiple providers, ran standard labs, and was repeatedly told that everything looked “normal,” even though I didn’t feel well. The frustration of not being heard, not having answers, and being left to manage symptoms without understanding why they were happening is something I know firsthand.

It wasn’t until I explored a functional approach that the missing pieces began to connect and true healing became possible. That experience fuels my passion for helping others who feel stuck, dismissed, or overwhelmed by their health.

Outside of client work, I enjoy spending time in nature, taking my dogs on walks, traveling with my husband, and taking indoor cycling classes!

Professional biography

I am a registered dietitian with specialized training in integrative and functional nutrition, with a strong focus on gut health, immune regulation, blood sugar balance, inflammation, and metabolic health. My work centers on identifying and addressing underlying root causes, rather than managing symptoms alone.

I take a food-first integrative approach to healing that recognizes health as the intersection of nutrition, lifestyle habits, mental and emotional well-being, and targeted supplementation when appropriate. Rather than relying on a single intervention, I view healing as a collaborative process that supports the body from multiple angles, using nutrition as the foundation, lifestyle changes to create sustainable routines, stress and nervous system support to promote resilience, and strategically selected supplements to fill gaps or support specific physiological needs.

My specialty areas include digestive health, women’s health, and autoimmune conditions. I am passionate about helping clients feel informed, supported, and confident as they improve their health.

Each client relationship begins with a comprehensive intake that explores nutrition, digestion, movement, stress, sleep, environmental exposures, supplements and medications, health history, symptoms, and personal goals. When appropriate, I may recommend functional or specialty testing, such as comprehensive stool testing, hormone and thyroid panels, nutrient status testing, immune markers, or food sensitivity testing, to guide a personalized, targeted care plan.
