Mack International LLC

Finding the right chief investment officer or family office CEO is rarely a posting-and-filtering exercise. Cultural alignment, generational fit, and discretion matter as much as credentials, and most family offices lack the internal infrastructure to run a rigorous search on their own. Mack International has operated exclusively in this space since 2002, conducting retained C-suite searches for single family offices, multi-family offices, family enterprises, and the wealth management firms that serve them.

Founded and led by Linda Mack, the firm positions itself around two parallel claims: a proprietary search methodology and a network built specifically within the family office and private wealth ecosystem. The firm operates across national and international engagements, with office presence in West Palm Beach, Nashville, Dallas, New York, and Chicago. Key service areas include:

• C-suite and senior executive search for family offices and family enterprises
• Strategic human capital consulting alongside placement work
• Cultural fit assessment as a distinct component of candidate evaluation
• Searches for firms serving ultra-high-net-worth families, not only the families themselves

The firm has received recognition through the Family Wealth Report Awards, including a 2024 win and a 2026 shortlist in the wealth management executive search category. That track record matters in a category where a single mis-hire at the principal level can destabilize governance or investment strategy for years.

The practical limitation for buyers: Mack International is a boutique with no disclosed pricing, and the model is retained search, meaning fees are committed upfront regardless of outcome in some structures. Families seeking a lower-cost or contingency-based approach will not find it here. This is best suited to family offices that treat a senior hire as a long-term governance decision rather than a staffing transaction.
