R.H. Investment Group

Robert H. Book, as founder and managing member, retains authority over all capital allocation. The firm does not publicly list any other investment committee members or outside advisors. Given the office's private nature, decisions likely involve a small circle of trusted professional services, though no names have been disclosed in public filings.

No. The firm is structured exclusively as a single-family office for the Book family and does not solicit or manage third-party investor commitments. There are no registered funds, no public 40-Act vehicles, and no evidence of co-investment syndication with peer family offices in any available corporate records.

Based on known entity structure and observable investment patterns, the firm concentrates on directly owned real estate and private credit, supplemented by limited private equity commitments. Real estate holdings are believed to be income-oriented multifamily and retail properties within the New York region, while credit exposure appears to funnel through established manager relationships rather than direct origination.
