The 19-year-old defender joined the Toffees from MK Dons in the summer of 2014 and earlier this month was rewarded with a long-term deal after breaking into Roberto Martinez's first team.
Galloway, who has made 16 appearances in all competitions this season, is thrilled to have committed himself to the Everton cause and is excited about a bright future ahead at Goodison Park.
"There is no doubt about it, I came to the best club for me and with the manager, staff and other senior players it was important to get that whole package," he told the Liverpool Echo.
"It is very hard to find that whole package in football but I have found it here and now I am just looking forward to learning a lot more.
"It was important to know that my future was going to be here at Everton and I am really happy for me and my family.
"They have always been a big part of my career and have been since I was a young boy. They come to all of my matches that I play, at least five always come - my cousins, my sisters and my parents always come.
"It has been like that from when I was a young boy. They all still live in Milton Keynes but even for the far away games they still come up. That is important to have the support of them."
