“Such an honor to be the best man at my brothers wedding. Witnessing their love be sealed under a beautiful Oak tree in front of family friends was such a special moment,” Derek said on Instagram.
“Like the tree May you Stand together tall and proud. May you always Go out on a limb for one another. To Stay grounded and dig your roots in deep so that you may weather any storm,” Derek continued. “And always continue to grow, stronger and higher reaching towards the heavens. And to always enjoy the view. Love you two.”
