The Authors



Mark Oristano has been a professional writer/journalist since the age of 16.  He grew up in suburban New York and moved to Texas in 1970 to attend Texas Christian University.  A major in Mass Communications, Mark was hired by WFAA-TV in 1973 as a sports reporter, the start of a 30-year career covering the NFL and professional sports.

Mark has worked with notable broadcasters including Verne Lundquist and Oprah Winfrey.  He has covered Super Bowls and other major sports events throughout his career.  He was part of Ron Chapman’s legendary morning show on KVIL-FM in Dallas for nearly 20 years.

In 1997, Mark began volunteering at Children’s Medical Center in Dallas, working in the day surgery recovery room.  (Or, the Post-Anesthesia Care Unit, if you like hospital talk.)  It was at Children’s that Mark got to know Kris Guleserian, first to discuss baseball, and later, to learn about the physiology, biology, and mystery of the human heart.

That friendship led to a joint book project, SURGEON’S STORY, about Kris’ life and career.

Kris Guleserian turned a cum laude degree in Greek classics from Harvard into one of the most important surgical careers in the country.

From medical school at Boston University, to internship and residency at Brown University Hospital, to fellowships at Boston Children’s, to her current job as Surgical Director of Pediatric Cardiac Transplantation at Children’s Medical Center, Dallas, Kris has been climbing the ladder, defying the odds, and making her way in a male-oriented world better than most of the men.

Her awards and honors, and her list of published articles in prestigious medical journals make for a CV dozens of pages long.  But that only tells part of the story.   A lifelong Red Sox fan, a devoted “foodie”, and a woman who is capable of standing on a small stool in the OR operating for 14 or more hours with no breaks of any kind, Dr. G stands only five feet tall, but as they say in the sport world, “She plays six-two.”  (Incidentally, she once wrote on an OR marker board after an 8-hour surgery, “If you can’t operate in heels, you can’t operate.”)

Dr. G has opened up her career, and her OR, for the purposes of telling this story.
