Mercy Clinic Internal Medicine Docs Discuss the Difference

OKLAHOMA CITY – Medical terminology can be overwhelming and vague. Endocrinology, obstetrics, phlebotomy, gastroenterology. Familiar folks either frequent the hospital as patients, or have a few letters behind their names. Even words understandable alone can be confusing when paired as a specialty. Like “internal” and “medicine.”

The group of providers at Mercy Clinic Internal Medicine work to make their patients’ lives easier, and that starts with explaining how internal medicine differs from primary care or family medicine.

“What makes internal medicine doctors a little different from primary care or family medicine is the focus,” said Jonathan Wilks, M.D., a provider at Mercy Clinic Internal Medicine. “We help patients manage chronic diseases such as diabetes, rheumatoid arthritis and heart disease by organizing medications and treatments – and ensuring medications and treatments all work well together.”

Darin Stockton, M.D., who joined the clinic when it opened in January 2012, agrees.

“We’re the air traffic controllers of medicine,” said Darin Stockton, M.D. “We help connect the dots. Many times, people who are aging or have chronic diseases see several health care specialists and have treatments or prescriptions prescribed by different people at different times. We help make sure all of those treatments and prescriptions are working well together, for the best interest of the patient.”

These providers see a variety of patients, and often serve as primary care physicians. More often than not their patients are over the age of 18.

“Having all four of us in one location means we can benefit from each other’s experiences and we can back each other up, if need be,” said Wilks. “It’s important to all of us to take time with our patients to thoroughly discuss their concerns. So, if Dr. Stockton is booked solid, but Dr. Wilson has an opening that day, the patient has an option to see a provider who knows their normal provider well, and no one is rushed through his or her appointment.”

At the end of March, David Wilson, M.D., joined Mercy Clinic Internal Medicine, doubling the number of doctors there.

Ross is a geriatrician, board-certified in internal medicine and geriatric medicine. She will focus on caring for aging patients. Ross graduated from medical school at The University of Oklahoma, earned a Master of Education with emphasis in gerontology from the University of Central Oklahoma, and completed a fellowship in geriatric medicine at The University of Oklahoma.

“I’m passionate about managing illness, promoting physical activity and helping my patients maintain independence,” said Ross. “Addressing the many health needs of our aging family members can be challenging and complicated, yet absolutely rewarding. It’s important to communicate effectively so my patients and their families can rest assured I’m looking out for their sincere best interests.”

Wilson is board-certified in internal medicine and received his medical degree from Rush Medical College in Chicago. He earned a Master of Science in computer science from the University of Chicago. Wilson is highly skilled in managing patient care using electronic medical records, which Mercy implemented nearly a decade ago, but is comfortable communicating with patients however they prefer.

“My patients’ time is valuable, so I work to respect that and explain things in ways that suit their lifestyles. We can communicate by email, or with good old fashioned telephone calls,” said Wilson. “Either way, I enjoy listening to what is important to my patients. Every day is different, and every patient is unique.”
