About PostRx Healthcare - St. Louis Gastroenterologist

Empowering Patients and Prioritizing Relationships

At PostRx Healthcare, we do not accept insurance for our consultation services. We believe that healthcare should be more accessible and affordable and that health insurance is important for large healthcare expenses like CT scans and colonoscopies.

We believe that digestive health and wellness is key to overall health. Contact us to schedule consultation and to create a treatment plan that involves diet, lifestyle modifications, medication, and psychosocial support. Healing the patient is our goal.

We've been busy…collaborating and creating relationships!

Healthcare is expensive and fragmented. Lack of effective communication and education only worsens healthcare delivery and outcomes. At PostRx Healthcare communication, education, advocacy, and collaboration are our focus. And, ultimately that focus fosters relationships with patients as well as other healthcare professionals resulting in better care for patients with chronic digestive disease.

We believe that truth and transparency create trust, and that trust can lead to lasting relationships as well as better care.

Meet Dr. Kreikemeier

Dr. Kreikemeier is passionate…about his family, his calling as a father and physician, and his faith. He enjoys people and celebrates relationships especially those with his patients. His motivation in creating this new practice was clarified during the pandemic where many of the dysfunctions of modern healthcare were clearly exposed. His personalized medical care model fits with his personality as well as his previous practice style where he, quite often, shared his cell phone with patients and family members with Crohn's disease or cancer. And, most importantly, Dr. Kreikemeier has been a patient in the broken healthcare system so is even more convicted to create solutions. Learn more about the direct care medical model that is innovating healthcare.
