I am a board certified neurologist who has been in practice since 1998. I completed my medical education at Emory University in Atlanta, GA (1992), and post-graduate training at Emory Affiliated Hospitals, The University of Virginia, and Vanderbilt University. In addition to my M.D., I have a Masters in Public Health (Emory-1991). Originally from New Jersey I live and work near Springfield, MO. I am married and have three grown children. I became interested in Functional Medicine while exploring my own health and performance as a cyclist, runner, and triathlete.

    Cāllie Maggard Chief Operating Officer


As Chief Operating Officer I have seen Sharlin Health & Neurology grow, evolve, and innovate health care delivery, and more importantly help our patients get the results they desire.  I come from a family with a strong management and business background which played a big role in my educational and professional choices. I have a Bachelors in Health Administration, and over 10 years of experience in management and customer service.  It has been an incredible journey to be with this clinic from the day we opened in November 2015.

I am an athlete and enjoy pushing my body and mind to reach a higher level of excellence.  I have competed in Tough Mudder races, Urban Warrior races, MS 150’s, as well as various other running and cycling events. I was a competitive cheerleader, as well as a dancer.  When I met my husband in 2011 his commitment to health and fitness matched my own, and this made it easy to stay on track.  Today, we share this with our two children by setting the example for them. This passion to provide a well-balanced life for my family carries over into my working life, and my interactions with our team and patients.  Here at Sharlin Health & Neurology we are interested in the entire person, mind, body and spirit.  I think it is important to have all aspects of your life in working harmony so that we can provide the same experience to our patients.

  • Rachel Wemple
    Rachel Wemple Registered Dietitian


As a registered dietitian, my passion is to help adolescents and adults reverse chronic disease. Most recently, my focus has been to solve the nutrition challenges for those affected by neurological conditions as diverse as migraines, Alzheimer’s and Parkinson’s disease, Amyotrophic Lateral Sclerosis, and multiple sclerosis. If this does not fit your need, I also have experience with various other conditions, including chronic kidney disease, obesity, metabolic syndrome, insulin resistance, fatty liver disease, hyperlipidemia, and complex gastrointestinal disorders.

It has been my honor to change people’s lives through food and functional nutrition science. I am the licensed clinical dietitian at Sharlin Health & Neurology. While the clinic is in Ozark, Missouri, I reach people from all over the world who either travel to me or come to them by a virtual meeting. After receiving my bachelor’s degree in Dietetics from Missouri State University, I furthered my education in Georgia, where I completed an Augusta Area Dietetic Internship. This provided experiences with end-stage kidney disease, and as a Diabetes Care and Education Specialist, I helped those afflicted by this devastating condition change the trajectory of their lives.

Here are a few of the things I am passionate about:

  • Whole foods nutrition
  • Meal plans tailored to the individual that are manageable and fun
  • Intermittent fasting and time-restricted eating for whole body optimization
  • Targeted supplementation and natural support, such as CBD, omega fatty acid measurements, and re-balancing, the biochemical role for B-vitamins in bioenergetics and methylation support
  • Probiotics and the gut microbiome
  • Gut-healing protocols, including the reversal of acid reflux and the discontinuation of destructive acid-blocking drugs

Originally from Joplin, Missouri, I have been married to Joshua Wemple for 20 years. I have three wonderful boys – Daniel, Jonah, and Owen. I am so fortunate to have the support of my family in my work and to be able to spend time with them outside of work. Speaking of fortune, I have a terrific dog named Jackpot who gets his name because rescuing him as a pup was like winning the big prize.

I got my passion for health from my father, who is a registered pharmacist. Ironically, he never wanted us, kids, to take medication. A sore throat was treated with gargling saltwater or a steam shower. My mother is a registered nurse. Because chronic diseases are prevalent in my extended family, my mother wanted us to avoid the same fate by feeding us the best home-cooked meals. I took what I learned and helped my Uncle Mark go from 440 pounds to a healthy 195 pounds. The experience transformed both of us and has made me even more determined to help others with similar frustrations.

  • Donna Webb
    Donna Webb Registered Dietitian


I’ve been a licensed dietitian, certified diabetes care and education specialist for over 25 years. I have worked in all aspects of nutrition care and management in hospitals, nursing homes, and group and individual nutrition counseling. 

According to my traditional nutrition education, I believed and taught that fat was bad in all forms and all efforts should be made to eliminate fat from the diet. I was a good soldier.

Then, around 8 years ago, I was at a dietitian meeting near Springfield. The message at that meeting was: You know, fat might not be as bad as we thought, and sugar might be a whole lot worse than we thought. 

I was knocked off my horse. I was personally and professionally distraught. 

But, I took a pause, and decided to dig into the research for myself. Everything I teach now is research-based. And I have embraced in my own life, and follow a diet now that is energizing, delicious and simple to follow. I have more joy now in helping people than any other time in my career.


I am an ACSM and ACE certified fitness professional with a holistic and realistic approach to fitness and wellness.

With over a decade of experience designing functional fitness programs and working with clients of all ages and fitness levels, I know that everyone can change and no one is beyond help. My mission is to start where you are in order to help build you up, not break you down.

I also appear on KY3 Ozarks Today as a FitLife contributor. I have also appeared in Oxygen Magazine as a “Future of Fitness” and have written for US News & World Report Eat + Run, and

My favorite thing to do to stay fit is to lift weights but running is becoming a close second. I’m not fast but I enjoy being outside, especially if it’s early in the morning while the world is still quiet. Outside of the gym or clinic, you’ll probably find me curled with a cup of tea and a book.
