Promoted via the Bostik League play-offs back in May after many attempts, the manager says the reality of being a National League club is now dawning.
He knows Dulwich are up for the challenge - and his players deserve the chance having taken them up.
Rose has today signed his second player of the summer in Ebbsfleet United winger Anthony Cook.
The long serving boss says he is not done there and is already counting down the days until the National League South gets underway.
He told us: “We haven’t brought too many in so far this summer.
“We want to keep this group together for a third season. They took us up and deserve the opportunity.
“We were always going to add players. It’s two so far now we have signed Anthony Cook and there will hopefully be three more.
“We are looking for one or two defenders and also a striker. There may be some progress in the next ten days but there’s no hurry. We are happy with where we are at.”
Rose thinks the Dulwich fans will take to new boy Cook instantly.
“He’s a wonderful player,” the manager said. “We are lucky to have him and I’m delighted we have managed to get the deal done.
“The fans will enjoy watching Cookie play and I think he will add real quality to our squad.”
