The People Who Walk With You
Every person on this team chose a different path.
They had the degrees, the hospital jobs, the clinic positions. They watched patients come in, get a prescription, and leave no better than they arrived. And at some point, each of them decided they weren’t willing to practice that way.
That’s what brought them here. Not just the credential — but the conviction that the body is designed to heal when given the right tools, the right environment, and the right support.
These are the people who will walk with you through your journey. You will know them by name. They will know yours.

Our Team
Founder & Functional Medicine Practitioner
Jennette Berry RDN,LDN
Jennette grew up as the eldest of four children in a small town in Kansas, watching her mother push through exhaustion for years — going to the doctors, doing everything right, but never really feeling heard. Her mother was eventually told she had a thyroid problem and put on medication. Her labs looked better. She felt a little better. But not really.
What her doctors never told her was that nine out of ten thyroid cases in women are autoimmune. They don’t test for it because it won’t change the prescription. The root cause went unaddressed. For Jennette’s mother, what followed was a cancer diagnosis. Within 18 months, she was gone.
Jennette had just completed her training in functional and integrative medicine. She knew the tools existed to help people heal differently. She knew what happened to her mother didn’t have to happen.
“I believe what happened to my mom didn’t have to happen — and yet it happens to so many. We can’t wait until it’s too late.”
So in 2011, she and her husband opened Functional Nutrition Resources in a small office just north of Tulsa. Fifteen years later, that’s still why she shows up every day.
Jennette specializes in autoimmune conditions, thyroid and hormone health, gut issues, and the complex cases that have stumped other practitioners. Outside the office, she and her husband are busy with their three children — splitting time between soccer games and family hunting trips.
Functional Medicine Practitioner
Heather Alexander, MS, RD
MS Nutrition, University of Central Oklahoma · Institute of Functional Medicine (IFM)
Heather’s interest in nutrition started in middle school, watching her parents and sister struggle with health issues. She also dealt with her own digestive problems and the anxiety that came with them. When her family started making lifestyle changes and everyone began to feel better, something shifted for her. She experienced firsthand what it meant to get your life back through nutrition — and she wanted to help other people do the same.
After graduating, she worked at hospitals and an outpatient clinic serving patients with diabetes. She quickly saw the same pattern: medications were offered, symptoms were managed, but patients weren’t actually getting better. Nutrition and lifestyle were afterthoughts. It was heartbreaking — and it felt unnecessary.
“I believe that our bodies are designed to heal when provided with the right environment and nutrition. I wanted to be part of the solution.”
At FNR, Heather brings that conviction to every patient she works with. She specializes in root cause evaluation and personalized clinical care, with a particular focus on the complex interplay between gut health, hormones, and immune function.
Outside the office, Heather is a mom to a six-year-old son and three-year-old daughter. Her family loves summer — swimming, being outside, traveling to beaches when they can. They run together to stay active and are passing good nutrition habits down to their kids one adventurous kitchen experiment at a time.
Functional Medicine Practitioner
Kate Lea, PharmD
PharmD, Southwestern Oklahoma State University College of Pharmacy · Institute of Functional Medicine (IFM)
Kate came to functional medicine from an unexpected direction. She earned her doctorate in pharmacy in 2011 — a credential that gave her a deep, precise understanding of how medications work in the body. And it was that same understanding that showed her, more clearly than most, what medications can’t do.
Prescriptions manage. They suppress. They lower a number on a lab report. But they rarely resolve the reason that number was elevated in the first place. Kate saw that clearly from inside the pharmaceutical world — and chose a different path.
“I changed the direction of my career because I am passionate about helping the people of our community make their dreams of full and joyful lives a reality, one day at a time.”
Her background in pharmacology makes her uniquely equipped to work with patients who are navigating multiple medications alongside their functional medicine program — understanding the interactions, the implications, and what’s actually driving the underlying need for each one.
Patients who meet Kate quickly discover what the team already knows: she has a heart of gold and a genuine passion for root cause medicine that shows up in every appointment.
Health Coach · Certified Nutrition Specialist
Emily Baker, CNS
BS Kinesiology, University of San Antonio · MS Nutrition & Functional Medicine, University of Western States · CNS · IFM Trained · Certified Holistic Nutritionist
Emily’s path to functional nutrition started with her own body failing her.
Over seventeen years ago, she began dealing with debilitating IBS, food intolerances, chronic fatigue, and hormone imbalances. She was later diagnosed with endometriosis and then autoimmune thyroid dysfunction. She went through the conventional medicine route looking for answers. She found none.
What she found instead was that her body could heal — despite being told otherwise. Through nutrition, lifestyle changes, and a root cause approach, everything changed. She understood for the first time why her body was struggling and what it actually needed.
That understanding became her life’s work.
Emily went on to earn a master’s degree in both nutrition and functional medicine, complete her CNS certification (the highest post-graduate nutrition credential available), train with the Institute for Functional Medicine, and earn her holistic nutrition certification. Her credential stack is one of the deepest on the team — built not just from academic pursuit but from personal necessity.
“I love guiding individuals through this process of reclaiming their power and reclaiming their lives.”
Emily specializes in complex chronic conditions, particularly autoimmune disease, digestive dysfunction, hormone health, and endometriosis. She works with patients to validate their experience, connect the dots between their history and their symptoms, and build the kind of understanding that makes lasting change possible.
Health Coach · Certified Nutrition Specialist
Lauren Burkowski, CNS
MS Clinical Nutrition & Integrative Health · CNS, American Nutrition Association · Certified Health Coach
Lauren brings both deep clinical training and real-world functional medicine experience to her work with patients. Before joining FNR, she spent years working inside a functional medicine practice, sitting in on initial client sessions, reviewing supplement protocols and nutrition plans, and meeting one-on-one with clients to make sure every recommendation was genuinely doable — not just clinically sound.
That last part matters more than it sounds. A plan that looks perfect on paper but doesn’t fit someone’s life doesn’t work. Lauren understands that the best functional medicine coaching happens in the space between the protocol and the person — where you meet someone where they actually are and help them take the next real step.
She specializes in autoimmune conditions and hormone health, with a particular interest in the intersection of stress, nervous system regulation, and the body’s ability to heal. Her approach is grounded in partnership — she works best with patients who are willing to show up, communicate honestly about what’s working and what isn’t, and trust the process even when progress feels slow.
Lauren recently returned from maternity leave and brings fresh energy and perspective to the team and the patients she serves.
Wellness Concierge
Lindsey Gaede
When you first reach out to FNR — whether it’s after a webinar, a referral, or finding us online at 11pm when you’ve finally had enough — Lindsey is the first voice you’ll hear.
As our Wellness Concierge, she guides every new patient through the onboarding process with the kind of warmth and clarity that immediately signals: you’re in the right place. She is the person who makes sure you know what to expect, answers your questions before you even think to ask them, and stays a phone call away throughout your journey.
Lindsey has had a lifelong love of nutrition and healthy living — she grew up exploring in the kitchen and has spent her career working alongside top chefs and educators, learning what it means to help people build a genuinely healthy life they enjoy. She came to FNR through what she describes simply as answered prayer — looking for a role where she could use her gifts to inspire and encourage others on a team that truly values one another.
“I enjoy inspiring and encouraging others in their own health journeys.”
Outside FNR, Lindsey and her husband David recently celebrated their 20th wedding anniversary. They have two teenagers — a son who plays football and baseball, and a daughter who runs track, plays volleyball, and dances. When they’re not cheering from the stands, the family is outdoors — fishing, hunting, hiking, or swimming. They have three dogs, including two German Shorthaired Pointers who are just as enthusiastic about the outdoor life as the rest of the family.
Operations Specialist
Ciarra Nugent
Ciarra keeps the practice running smoothly so that every member of the clinical team can focus entirely on patient care. From systems and scheduling to the operational details that make a complex practice work, she is the steady hand behind the scenes that every patient benefits from — even if they never see it directly.
Client Engagement Specialist
Tara Roberson
Tara joined the FNR team in February 2025 as our Client Engagement Specialist. She is often the voice you hear before your initial evaluation — reaching out to confirm your appointment, answering last-minute questions, and making sure you and your significant other are prepared and ready for your time with the team.
Her role is one of the most important in the practice. The quality of every patient’s first in-office experience often starts with the conversation she has the week before. She has grown quickly into this role and the whole team has seen it.
