Dr John.png
Dr. John Davidhizar believes medical care should be accessible and timely. Doctors should be directly approachable & responsive (instead of through an answering service), an advocate for you in other environments (in the hospital, E.R., and with other specialists), and a trusted advisor who is accountable to you, knows you by name and cares about protecting your most important asset, your health. A practice should have transparent pricing with no surprises, and be free of government and insurance dictates that oftentimes do not have the best interest of the patient in mind.
Dr. John was born and raised in Texas, coming from a family of 12. He earned a Bachelor of Science in Biomedical Sciences from Texas A&M University, completed medical school at the University of Texas Medical School in Houston, and is board certified in Family Medicine. He started his DPC practice in July 2014 and is excited about providing care at a practice that makes possible many of the health care principles he is passionate about.

Dr. Hannah Shelton

Conroe, Texas

Hannah Shelton Attachment - Hannah Portr

I was born in Austin, Texas but raised three hours north, up the I-35 corridor in Dallas. While attending Highland Park High School, I ran cross country and upon graduation majored in psychology at the University of Georgia. Go Dawgs! Texas called me back home to pursue my lifelong dream of becoming a doctor. After obtaining a master’s degree in Biomedical Sciences from The University of North Texas Health Science Center, I completed my Doctorate of Medicine at the Texas College of Osteopathic Medicine in Fort Worth. Choosing family medicine as my specialty was an easy decision because I value building relationships with patients and their families. In addition, I have found it extremely rewarding in caring for patients of all ages, infants to the elderly. I completed my extensive training with the Conroe Medical Education Foundation in affiliation with the Lone Star Family Health Center. The current fee-for-service, insurance-based model of medicine prevents me from practicing medicine as I have always dreamed and therefore is my reason for joining the Direct Primary Care movement. This DPC model is just as my Papa practiced medicine 40 years ago, with a leather doctor’s bag and a big heart for his patients. I hope to return primary care to its roots of purity with a direct, uninterrupted relationship between doctor and patient. While not practicing medicine, I enjoy traveling, scuba diving, jogging, wake-surfing, cooking, spending time with friends and family and playing with my rambunctious yellow Lab, Remy. I look forward to having the opportunity to spend time with you and your family and I am excited to be a true Advocate for your health.

Dr. Thomas Kay

New Braunfels, Texas

Dr. Kay- Picture.jpg

I am a Board Certified Family Medicine physician who has been practicing for more than 20 years, taking care of newborns to century-ians. Since medical school, my great love for medicine has always been caring for all ages, helping with acute illnesses (from common colds to serious problems), chronic health concerns, disease prevention, and my favorite, wellness promotion. While gaining experience in treating patients the world over, I have come to see a common thread, patients want to be heard and cared for – we all do actually Over the last couple decades, I have become disillusioned with the trend of doctor/patient relationships. In our current model, we often have no time to address the real health concerns of our patients.

In the time that my family and I have spent living on the mission field in Romania, as well as time in Uganda and Haiti, I have seen medicine practiced a variety of ways and this allowed me to begin thinking outside the box. When I began to consider what an ideal medical practice would look like, I landed on Direct Primary Care. In this model, I know my patients – every one of them, discuss their medical needs, and partner with them to create health.
