Rosemont, a private investor in employee-owned asset and wealth management firms, agreed to invest in Landmark Management, a multi-family office with more than $4bn in assets under management. Financial terms were not disclosed. "We are thrilled to form this partnership with Landmark—which in many respects represents the ideal Rosemont investment—after several years of discussions. Landmark has provided distinctive investment advice and valuable services to a limited number of enduring client families over a long period of time. With Rosemont’s support, it will continue serving these families as well or better for many years to come," Brad Mook, Rosemont Managing Director.
