Age 39 | Pediatric interventional cardiologist, Pediatric Cardiology P.C.

John Lozier can’t remember a time when he didn’t want to be a doctor.

After spending years “cramming information into his brain” in medical school and more years of residency to put theory into practice, the Des Moines native discovered affinities for cardiology and working with children. Following a four-week rotation at the University of Iowa Hospitals and Clinics with a pediatric cardiologist, “it became very obvious that this was what I wanted to do,” said Lozier.

In 2007, the highly trained Ivy League graduate moved to Des Moines to practice as a pediatric interventional cardiologist. In that specialty, Lozier uses heart catheters to assess and repair a wide range of cardiac conditions on patients who are in many cases newborns or infants. The highly competitive microspecialty has only about 300 positions around the country.

“The spectrum of conditions we deal with is very challenging and interesting,” said Lozier, who averages about two procedures a week. Some procedures are purely diagnostic, while others may involve opening up narrow blood vessels or patching a hole in the heart.

As part of a medical team from his pediatric cardiology group, Lozier for the past five years has participated in the Yucatan Charity Project. Each year, the team sees between 300 and 350 patients in a week. About 25 of the most seriously ill children are brought to Des Moines for heart surgery.

“That was something that really helped tip the balance for me in deciding where to take a job,” he said. “And it’s really fun, really rewarding.”

Lozier and his wife, Nicole, have an 8-year-old son, Charles, and 5-year-old daughter, Elise.

Despite a busy medical practice, Lozier finds time to volunteer for his children’s schools.

“You just kind of scrape whatever (time) you can find from the calendar,” he said. “My wife is a real inspiration because she lives for our kids and to make the world a better place. I just kind of follow her lead.”

Five reasons he’s a 40:

• He chose to return to Des Moines to provide a highly skilled medical specialty for children.

• He volunteers annually to help children in Mexico receive lifesaving medical care.

• He’s active in two professional organizations that research new ways to treat congenital heart disease.

•  As 2011-12 board president of Plymouth Nursery School, he helped establish an endowment and coordinated revision of the school’s bylaws.

• He earned a degree in molecular biophysics and biochemistry at Yale University and a medical degree from the University of Iowa.

Mentor: Dr. Tom Becker

Fun fact: He and his wife are expecting their third child this summer.
