Frequently asked questions
Who runs investment decisions at Diagonal?
The firm is co-led by Managing Partners Rodolfo 'Rudy' Rake and Santiago Rey. Rake is a former professional tennis player who transitioned into wealth management; Rey is the allocation specialist responsible for portfolio construction. Eduardo Rehder oversees wealth management as Senior Vice President, and Gisselle Balza supports portfolio operations as Senior Portfolio Associate.
Does Diagonal invest in funds or only direct deals?
Published holdings point toward direct ownership in real estate rather than fund commitments. The firm owns commercial property at its New Jersey headquarters and at least two mixed-use parcels in Longmont, Colorado. Its wealth management services suggest some liquid-securities advisory, but the primary visible deployment is direct real asset ownership.
What is Diagonal's geographic investment footprint?
The firm's known real estate holdings sit in two distinct markets: suburban northern New Jersey (Randolph, Morris County) and Colorado's Front Range (Longmont, Boulder County). Longmont has become a notable secondary market for family office real estate capital, offering yield and growth outside Denver.
How is Diagonal structured — as a single family office or a multi-family office?
Diagonal Investment Office operates as a multi-family office, serving several families from its Randolph, New Jersey base. The firm combines direct real estate ownership, wealth management, and portfolio advisory under one structure rather than functioning as a single-family vehicle.
Does Diagonal maintain any operating businesses alongside the investment office?
No operating businesses have been disclosed beyond the wealth management and real estate holding entities associated with the firm. The principal assets visible in public records are commercial and mixed-use properties held directly.
