He went back to finish the work he started in one of Haiti's most impoverished areas...and found himself in the middle of a violent riot.
"There is an incredible need", Dr. Flemming says. "We also left behind 300 orphans in that area and numerous extremely poor people."
Dr. Flemming and his team raised money all year to build a medical clinic for that region, but when he returned to Haiti last month, he discovered a desperate and angry mood had taken over the country.
After the earthquake, the people endured a hurricane, a cholera outbreak, and then, a disputed election.
"People took to the streets to express their dissatisfaction", Flemming says.
"Unfortunately in that process, there was a lot of damage done, a lot of people hurt."
As a former Army doctor, Flemming is no stranger to unrest... but this was different. He quickly realized he needed to cut his trip short, and get out. the team tried to make it to the airport. but were stopped short.
Flemming says: "We got to the edge of our village that morning when we were stopped and people said 'If you try to make it to the highway you will never make it because there is too much rioting up ahead and you will get hurt, there is no question about that.''
So they tried the backroads... and found themselves in an even more dangerous situation.
"Right before us were the rioters, they had a United Nations vehicle surrounded at that point and they were throwing bottles and rocks and hacking at the tires with the machetes that they had.
Unfortunately there was sa slldier that took a rock about this size to the side of his head... saw him crumple over. we said, 'Oh, this isn't good', so we backed out that alleyway and continued further down."
They tried to flee, but quickly ran out of road.
"We were trapped. We knew they were coming our way, we couldn't back up. This is not good. We have no protection. I told the driver, our host, 'Just step on the gas, because if we stop or we slow down here we are dead.' I knew we would be dead at that point. "I knew we were going to hit some people and hurt them, but at this point, it's survival. This crowd was out of control.
"A man jumped into the back of the truck and was pounding on the roof of the truck, and while there is screaming going on, back and forth, i say to the driver: 'What is he saying?' He's saying he is the leader of the village and to drive straight ahead, and as long as he's with us, Nobody will hurt us."
That man was right. The rioters let them pass. Eventually Flemming and his team made it to the airport and escaped the chaos.
Flemming says his mission isn't complete in Haiti. He will be going back, when he's confident that it's safer.
