About

Big Tree Medical Home is a direct primary care medical practice in Columbia, Missouri. We bring cutting-edge primary care ideas to solve the healthcare crisis in mid-Missouri. Our mission is to save our patients and businesses money on their healthcare bill while providing top-notch care.

We do not bill insurance, so it doesn’t matter to us if you have the best insurance or no insurance. Our services cost the same. We can provide information to you our patient if you want to send it in to apply to your deductible. We also focus on preventative medicine and not just treating symptoms but getting to the root of the problem.

Big Tree is the brainchild of Dr. Adam Wheeler and his wife, Jen. Dr. Wheeler formerly worked for Tiger Pediatrics, a large pediatric practice in mid-Missouri known for its excellent, relational care.

We are changing the financial aspect of health care by ending the fee-for-service payment structure for primary care. However, we provide the same, and most cases better, patient care. One of our primary purposes is to improve the community and state where we live.

We realize that getting care is both time consuming and expensive.  We try to utilize modern technology (video-based visits, text messaging, etc whenever it is appropriate).  This both saves time and money.
