“I pretty much did what every surgeon in the military has been doing,” Eppinger says. “When you’re deployed, you do everything. You’re not just a heart surgeon. Most of us are trained as general surgeons first.”

Dr. Robert Bjoraker, an anesthesiologist, joined the U.S. Air Force in 1983 as a chemical engineer and served for three years at Wright-Patterson Air Force Base in Greene County, Ohio.

Dr. Michael Pierson, an anesthesiologist, served in the U.S. Air Force at Lackland Air Force Base in San Antonio, Texas, from 1988 to 2000 in reserve and active duty roles.

Dr. Jon Henry, an orthopedic surgeon, served in the U.S. Army Reserve, Medical Corps from 1996 to 2008 as an orthopedic surgeon.


He joined the Army Reserves during his orthopedic residency and did two combat deployments in Afghanistan and one in Iraq.


His service goal was to provide excellent orthopedic care for our military personnel and he says his military experiences enhanced his skills and confidence as a civilian surgeon.


Henry is also proud and humbled by his time spent in the military.


“My number one realization from my own military experiences, especially from my combat service, is a far greater appreciation and respect for our veterans, for the sacrifices they and their families have made to benefit our country,” Henry says. “Our freedom is based on their honorable service and sacrifice.”

Dr. Jeff Shere U.S. Army Veteran

Dr. Jeffrey Shere, an ophthalmologist with BayCare Clinic Eye Specialists, joined the U.S. Army in 1992. After completing his four-year ROTC, or Reserve Officer Training Corps, in 1996, he was commissioned as a Second Lieutenant and attended medical school.


In 2000, he entered active duty as a Captain in the Army. Over the next 16 years, he served as the Chief of the Ophthalmology Service at Martin Army Hospital in Fort Benning, Georgia, as the Chief of Ophthalmology at the Army Institute of Surgical Research, and he worked in a teaching position as an attending vitreoretinal surgeon in Washington.


In 2016, he transitioned out of active duty.


“I made the decision to transition into the Army Reserve and to take my current position at BayCare Clinic so my family and I could move closer to our extended family,” Dr. Shere says.


He feels honored and proud to be part of the Army.


“Most of my professional career has been spent among Soldiers, Sailors, Marines, and Airmen. Each day of that career I was humbled by their example of selfless service. There was no greater honor to be entrusted to take care of our nation’s greatest citizens,” he says.


His current reserve unit is a head and neck surgical augmentation team in St. Louis, Missouri.
