OSF Medical Group


Mark Nafziger - Chief Executive Officer, OSF Ambulatory Care / Chief Administrative Officer, OSF Medical Group

Mark Nafziger "OSF is built on a great foundation. Few organizations have such a unique past... and are so well prepared for future success."

Mark Nafziger, Chief Administrative Officer, joined OSF in April, 2011. "The Medical Group is continues to grow," he says. "And that means more focus on the patient experience, with the same superior care offered wherever you are in OSF HealthCare"

As the CAO, Mark provides leadership for the OSF employed physician enterprise; this position encompasses the OSF Medical Group and our Neurosciences and Cardiovascular Service Lines.

Mark came to OSF from Parkview Health System in Fort Wayne, Indiana, where he served as the Executive Vice President and Chief Operating Officer. An $800+ million non-profit organization made up of six hospitals, Parkview also included 250 employed physicians at Parkview Physicians' Group, a joint venture orthopedic hospital, surgery centers and other ancillary operations.

Why leave to join the OSF family? "OSF is built on a great foundation," says Mark. "Few organizations have such a unique past, and are so well prepared for future success."

Mark's family includes Alecia, a legislative assistant for the Indiana House of Representatives and law student at University of Indiana, and Ty, a junior at the University of Illinois majoring in business. Outside of work Mark is "an avid motorcycle rider" who also loves farming with his brother in Hopedale, fishing, golfing, and restoring old cars.

Stephen Hippler, MD - Senior Vice President, Clinical Excellence

Stephen Hippler, MD "I don’t remember ever wanting to do anything but become a doctor. It is truly a calling."

Dr. Hippler's role as Senior Vice President of Clinical Excellence is a newly created position. Why? "We are at a crossroads in the delivery of health care," he says. "It means more than just taking good care of those who visit our offices; we must concern ourselves with the entire population of patients. Instead of being structured around a single provider, we will develop teams who will take responsibility for the ongoing care of patients."

Dr. Hippler has practiced internal medicine for more than 20 years; he joined the OSF family in the mid-1990's. He received his MD from the University of Illinois College of Medicine and completed his residency in internal medicine at Mayo Clinic. "I don’t remember ever wanting to do anything but become a doctor," he says. "It is truly a calling."

Though he has taken on an important administrative role, he continues to see patients. "It's important to maintain that contact," he says, "to understand patients' needs and what physicians do. Our new electronic medical records system (Epic), for instance, will have a huge impact on care. Epic can help us create the tools, reminders and registries to address the health care needs of our populations. It’s all about staying well, staying informed and engaged... and out of the hospital!"

Dr. Hippler and his wife, Rita, met in college and have been married for thirty years. They are the parents of 26-year-old triplets: Christopher, a meteorologist in Houston; Mallory, who is finishing up her master's degree in clinical mental health counseling; and Phillip, who lives at home. Outside of work Dr. Hippler enjoys golf and reading, but most of all, running marathons, "So far, 21 of them, from Boston to San Diego to Chicago."

Mark Povich, MD - Vice President, Michigan Region

Mark Povich, MD "I love taking care of people. As a physician, I have the honor of establishing long-term relationships and helping in times of need."

Never doubt the power of suggestion. Mark Povich was just a little guy, maybe ten years old or so, when an aunt remarked, "You know, you'd make a good doctor."

"That planted a seed," says Dr. Povich. He went on to graduate from Alma College in Michigan, attend medical school at Michigan State University and do his residency in family medicine in Lansing.

Then it was goodbye to Michigan, for a while anyway, and hello Minot, North Dakota to fulfill his US Air Force obligation. Minot was remote, "...but it has a beauty all its own," he says. And the work was exciting. "In addition to taking care of families, I was a flight surgeon, which meant providing specialized care for the personnel who fly helicopters and B-52 bombers, refueling tankers, and intercontinental ballistic missile crewmembers."

Born and raised in Saginaw, Dr. Povich was happy to return to his home state, eventually joining the OSF family in 1995. "I love establishing long-term relationships and caring for people," he says. "Many of the babies I delivered I now see as teens."

As Medical Staff President, Dr. Povich divides his time between seeing patients and performing administrative duties. He directs the medical staff at our various clinics, works together with them to improve quality and is active in recruiting new physicians. "It keeps me going!" he says.

Dr. Povich and his wife Carol met in college and have been married for over 35 years. They are the parents of nine children, ranging in age from 33 to 13. Jordan is finishing up his family medicine residency in Marquette and will be joining OSF soon; Jotham is a civil engineer with the Army Corps of Engineers in Davenport. He and his wife just had their first child. Jocelyn lives in Dallas with her husband; Joyanne and her husband live in Oklahoma City and are the parents of one child. At home are JoHannah, the twins Josiah and Joseph, Joliette and Jorge. And Carol has home-schooled them all!

Outside of work, Dr. Povich enjoys his family, kayaking, camping, snow shoeing and skiing.

Charles Dennis, MD - Vice President, Central Illinois Region

Charles Dennis, MD "Focusing on the Mission of The Sisters allows all of us to do our best, for our patients, our coworkers and the community.  But first, always our patients."

Born in Gibson City and raised in Champaign and Eureka, Dr. Dennis heeded the sage old advice to "Go west, young man."   After graduating with his bachelor's in biology from the University of Illinois, he headed to Houston, Texas where in 1986 he earned his MD from Baylor College of Medicine.

He came back to the Midwest for an internship and residency in internal medicine/pediatrics at the University of Michigan Hospitals.  And then Texas beckoned again, when in 1990, he finished his residency in Baylor’s combined internal medicine/pediatrics program.  Until 1994, Dr. Dennis served as a physician in the US Air Force, at Carswell and Dyess AFB hospitals in Texas.

"Family brought us back here," says Dr. Dennis.  "When the kids were school age, we really wanted to be near our family in central Illinois and the Chicago area."   After seven years with the Carle Clinic, he joined OSF Medical Group and now serves as Vice President, Central Illinois Region.

"I always tell people that I feel like I can have more impact with OSF. Working together with the hospital, we strive to improve health care and expand our scope of services. I’m particularly interested in bringing new, highly qualified people to this community."

Dr. Dennis’ outside interests include higher education (he recently earned his MBA in health care from the University of St. Thomas), home computing, digital photography, gardening, woodworking, fishing, and do-it-yourself projects.  The last four hobbies are particularly enjoyable since he, his father and brothers are currently building a lakeside cabin on 150 acres in southern Illinois!
