Meet the Staff

Dr. Roeser, Founder

Dr. Roeser, Founder

Dr. Roeser, a board certified internal medicine physician, founded Integrity Medicine, LLC in 2004 in an effort to distance himself from impersonal corporate medicine and work toward excellence in medicine through a Christian perspective.

In 2017, Integrity Medicine was converted to a Direct Primary Care model in response to government and insurance mandates forced upon healthcare providers. These protocols and regulations often prevented or unnecessarily delayed patients from getting the healthcare that should be afforded them. These infamous denials for radiology or specialist referrals, prior authorizations and step edits for prescription medications, and waiting periods for labs are now a thing of the past.

Before Integrity Medicine, Dr. Roeser studied at Wichita State University and the Oklahoma State University College of Osteopathic Medicine, where he earned the Internal Medicine Award for Excellency.

Dr. Roeser practices in the clinic as well as the in-patient setting at Newton Medical Center where he is a member of the medical staff. He’s proficient at performing upper endoscopies and colonoscopies and he is a preceptor and mentor for medical students and participates in medical missions with Medical Ministry International to the Dominican Republic.

“I love the interaction with patients and the opportunity to coach them through complicated medical issues. I’ve learned that you don’t treat heart disease, diabetes, or cancer. We diagnose and treat patients that have these conditions.”

Dr. Roeser and his wife, Michelle, attend Pathway Church in Wichita. He is an avid reader, loves exercise, college football, a skinny latte with an extra shot of espresso, and sharing a good joke.

Elizabeth is a graduate of the Wichita State University PA program, and she’s been well-known to the Newton community for the last seventeen years. Prior to working with Dr. Roeser, she worked in a local primary care family practice setting.

She enjoys caring for a wide variety of patients (ages fourteen and up) for both chronic and acute medical issues. Her schedule often includes complete preventive care such as school physicals, well woman exams, screening lab review, or pre-employment physicals.

Elizabeth can independently evaluate and treat patients with common medical problems such as diabetes and hypertension. She is also happy to see patients for urgent care issues, and has room in her schedule for same-day appointments as needed.

Dr. Roeser and Elizabeth make it a point to practice as a collaborative team for excellent medical care. She will confer with him at any time if needed so they can provide excellent medical care in a safe environment together.
