From our couples
Brianna & Dan
"Getting married on Cathleen Stone Island was nothing short of perfect! We worked with Denise and Mary Kate, who were so organized, so efficient, so attentive to detail, and so patient. For a bride and groom who didn't want to be too burdened by details, it was really easy, because they organized and communicated everything with us and our vendors.
The venue is so naturally beautiful, and the ceremony and reception venues are unmatched, with views of Boston in the background. Highly recommend this venue for a couple who doesn't want to be totally traditional and who loves the natural beauty of the great outdoors!"
