About Me...
Hello! I'm Rheba Casteen, Registered Dietitian and Functional Diagnostic Nutrition Practitioner.
I've been married for over 20 years, have two loving sons, and two adorable dogs. I love cooking and baking, being in nature, starry skies and colorful sunsets, and cherished time with family and friends.
I believe STRESS, in many forms, is the underlying cause of preventable dysfunction and disease. I'm passionate about true healing that's possible when the body is supported physically and emotionally at a foundational, cellular level. I'm committed to helping you get to the root of your health problems, to feel and look your best, in order to live the life you desire and deserve.

I use a thorough assessment of symptoms paired with functional lab testing to uncover a person's unique, sometimes hidden, stressors, which are healing opportunities for the body. Working together, I guide you through a tailored, holistic nutrition and lifestyle program, customized to fit your needs, using proven natural therapies to transform your health, and your life.




Welcome...
I'm glad you're here!
If you're always tired, struggling with digestion or weight gain, dealing with a specific health condition,
or you just aren't feeling like yourself,
You are not alone!
There are likely underlying stressors and imbalances affecting multiple aspects of your health.
Often, stress is thought to be only mental or emotional, and it's chalked up to being "a normal part of life."
Yet, physiological stress can come from other sources: physical stress (pain, injury, surgery), biochemical stress (waste byproducts from normal cells or pathogens), or environmental stress (toxins in our food, air, and water).
Too much stress, in any form, can wreak havoc on your health and affect how you function in everyday life.
Over 75% of U.S. adults report physical or emotional symptoms of stress. And, more than 65% of U.S. adults are overweight or obese. Research shows that up to 70% of doctor's visits are related to stress.
Excess stress can negatively impact the body and mind, leading to many seemingly unrelated or general symptoms that can be explained away, for a time.
Symptoms are signals from your body that something out of balance. They are signs of metabolic dysfunction and if not properly addressed, the underlying imbalances can progress to disease.
Years of stress in my own life led to symptoms of fatigue, weight gain, food cravings, rising blood sugars, extreme bloating, trouble sleeping, difficulty concentrating and poor memory.
Being tired, stressed, irritable and at risk of being diagnosed with Diabetes is not what I had planned for my life. I used functional lab testing to find the underlying reasons for my declining health. The results helped me understand why I didn't feel like myself anymore.
I made some necessary changes to my diet and lifestyle, which included supplements that supported digestion, reduced toxins, cleared parasites and promoted hormone balance. I was able to reduce the total stress load on my body, which led to improved energy, mood, digestion, and better blood sugar control.
I share this to let you know that I have firsthand experience of the "metabolic chaos" and unwanted symptoms that result from chronic mental, physical and environmental stress that plagues us all in this modern world.
Some people turn to special foods, alcohol, smoking, medications, or other solutions that do not address
the root cause and often make the problem worse.
That's why I offer a holistic and comprehensive approach to help you transform your health naturally.
Start having better digestion, better sleep, more energy and self-confidence, shed excess weight naturally and feel the best you've felt in years.
Functional testing and natural therapies can be effective, first-line options that empower you to stop outsourcing your health and wellbeing to the medical system.
If you're tired of feeling sick and tired, and ready to take back your health and vitality,
This is the simple health solution you've been looking for!
Let's uncover your body's healing opportunities and set you on a clear path to your best health yet.
In Health and Happiness,
Rheba

For years, my digestive problems interfered with my daily life.
Rheba gave me hope that I didn't have to live attached to a bathroom!
She educated me on gut health, gave me an easy plan to follow and encouraged me not to give up.
Her bubbly personality and trusting demeanor felt like I was talking to an old friend.
Now, I feel like I'm in control of my body again.
ROBIN
IBS
I recommend Rheba as a health coach and nutritionist!
I've had IBS for a few years.
Rheba helped me select the foods that I needed to stay away from.
She gave me guidelines to follow, was very encouraging, and followed up on a regular basis.
Since I know more of what to eat now, I feel so much more comfortable.
SHELVIE

She was so kind and genuinely cared about my health and getting better.

I am truly grateful for her wisdom, knowledge and expertise.
