 If anything with Marines, we have to slow you down." Those words are ironic, coming from Dr. Bill Crisoff, because he has done the exact opposite. Accelerated his life, left his civilian practice, and petitioned former President Bush for enable commission, all at 60 years old. Traditions of military service usually pass down from generations, and that's what makes Crisoff's story so unique. His sons, Nathan and Austin, were commissioned in the Marine Corps at the beginning of Operation Iraqi Freedom. But in 2006, Nathan lost his life in Fallujah. So the doc took his son's call of service from there. And on this day in the Pentagon, the Navy gave back to Dr. Crisoff. With his wife and Austin on hand for the honors, he was promoted to commander. I've been inspired by my sons and their dedication and equipment to service, so I felt like I earned this rank and worked hard for it, and I'm delighted to be able to be an O5 in the Navy. Commander Crisoff will now return to the orthopedic department at Camp Pendleton's Naval Hospital to continue to rehabilitate our wounded warriors. From Washington, I'm Sergeant Todd Hunter.
