"People thought thousands and thousands of people may have their lives ended, and the number is a very small number, which is a great tribute to you," Trump said to the first responders.
He praised FEMA and the Coast Guard and "the job you've done in saving people and saving lives."
Trump also said they are "way ahead of schedule" in restoring power back to parts of Florida.
Trump addressed what he called the "very special problem" in the Florida Keys, where 90 percent of homes had at least some damage, according to FEMA.
"We're working very hard on that, and we have a lot of goods out there, a lot of water, food, a lot of everything," the president said.
He also went to Naples, Florida, to meet with Hurricane Irma victims.
"We are there for you 100 percent," Trump said, as he toured the damaged neighborhood, promising that he would be back to Florida “numerous times.” He and the first lady handed out food and shook hands with the hurricane survivors.
This is the third trip Trump has made in response to a natural disaster. After record flooding from Hurricane Harvey devastated parts of Texas earlier this month, Trump made two visits, first to Corpus Christi and Austin on Aug. 29 and later to Houston on Sept. 2.
