Mark Ivanisin, a U.S. Army Corps of Engineers Pittsburgh District operations supervisor for navigation on the Allegheny River, poses with his dog, Maddie, for a portrait in his home in Pittsburgh, Dec. 17, 2021. Earlier this year, Ivanisin spent 52 days in the hospital fighting for his life against the COVID-19 virus and the pneumonia that followed. “I feel like I’m part of the Pittsburgh District family. I’m grateful for so many people who were there for me and my wife, giving me their thoughts, their support and their prayers,” Ivanisin said. “As far as the prayers go, I used every ounce of prayer that came my way. I didn’t leave anything on the table. Anybody who sent prayers, I used every bit.” (U.S. Army Corps of Engineers Pittsburgh District photo by Michel Sauret)
