Empowering Your Wellness Journey with Functional Medicine in Texas

At Core Functional Medicine, we believe in breaking away from the “sick-care” model by empowering individuals to take control of their health and achieve optimal wellness. Our mission is to provide personalized, science-backed care that focuses on identifying and addressing the root causes of health issues rather than just treating symptoms. The average medical clinic physician spends an average of 7 minutes with each patient. This fails to identify the root cause, doesn’t prioritize the patient, and is a big component of why America has a healthcare crisis.

At Core Functional Medicine, we spend an hour with each new client to build a relationship and truly understand their health goals and struggles. We work together with the patient to develop a plan that suits their lifestyle needs, seeing tremendous progress time and time again. Through our telemedicine platform, we make it easy and convenient for you to access cutting-edge and cost-effective therapies, including Comprehensive Lab work, GI Mapping, Food Sensitivity & Micronutrient Testing, Weight Loss Management, Hormone optimization, and Peptide therapies.

Let us help you unlock your full potential and live your best life.

What Our Patients Are Saying

Average Star Rating:
Rated 5 out of 5
I had been struggling with mental fog and fatigue despite maintaining a healthy diet and what I believed was sufficient exercise. I knew something was off—almost like my check engine light was on—but I didn’t want to go through the hassle of a doctor’s visit only to be told everything was “normal” or be prescribed medication with potential side effects. Kasey made the process seamless, helping me set up lab tests with a reputable facility in my area. The entire experience was far easier than any doctor’s visit I’ve had before.
Since working with Mrs. Netherland, my life has changed for the better. I have more energy and feel like myself again! She is incredibly knowledgeable, kind, and truly cares about her clients.
After seeing multiple doctors with no answers, Kasey was the only practitioner who truly listened and got to the root of my hormonal and thyroid imbalances. Her expertise in functional medicine not only provided an accurate diagnosis but also guided me through a healing process that completely transformed my life. I’m so grateful for her personalized approach and dedication to real solutions!
I had a nasty shoulder injury requiring surgery. My doctor said it would be 6 months before I could return to jiu jitsu and a full year before I felt fully recovered. I met with Kasey on a recovery plan before surgery and implemented her recommendations to expedite recover utilizing BPC 157 and TB 500. Following her recommendations, my doctor fully released me back to jiu jitsu in 13 weeks!
Kasey is awesome, she is very knowledgeable and caring. I have been using her for over a year and she has made a dramatic impact on my health. I am 61 and in the best shape of my life.
I’m a 44 year old healthy male but have struggled with sleeping my entire life. For the last decade, doctor after doctor has been putting me on Ambien, which I was never a fan of, but needed in order to get more than an hour of REM sleep every night. Kasey is the only practitioner who dug deep into why I wasn’t sleeping rather than just writing me off as a “bad sleeper.” Her lab panel review was very thorough and uncovered some deficiencies that every other physician had failed to recognize. Within 2 weeks of meeting with Kasey, I was fully off the Ambien, sleeping through the night, and waking rested.
Kasey is the most down to earth, knowledgeable, and kind medical professional I have ever met! I never felt rushed in any of our appointments and had her fullest attention. I feel amazing and have made my husband sign up as well!
