One of the ways of ensuring that Altair continues to remain an independent, employee-owned firm is by extending ownership opportunities to new partners. To this end, we are so excited to welcome Rachael Halstuk Mangoubi and David Lin who joined the Altair ownership group effective as of January 1st, 2021.

Rachael came to Altair in 2016 from Mesirow Financial. Her depth of skills across investment oversight, estate and financial planning enable her to problem solve and develop customized solutions to fit the unique needs of her clients. Her understanding of the needs of complex client families and her ability to mentor others across the firm make her an exemplary asset to Altair. Rachael began her career in investment banking, advising family business owners and entrepreneurs within the mergers and acquisitions process.

Rebekah Kohmescher, Altair’s Chief Executive Officer, notes “Rachael’s clients appreciate her continuous outreach and her thoughtful approach to service. We feel very fortunate to have Rachael on Altair’s leadership team.”

David was recruited to Altair in 2017. As head of the research team, he plays a key role in the due diligence and selection of managers. David also serves on Altair’s Investment Committee, the central decision-making body for the firm’s investment strategy and market outlook. Prior to joining Altair, David held various positions at William Blair, a global investment banking and asset management firm headquartered in Chicago. He started his professional career in the valuation consulting group at Deloitte.

Chief Investment Officer Jason Laurie, a founding partner and Managing Director of Altair, credited Lin with leading critical strategic initiatives that have meaningfully benefited client portfolios. “I am delighted to welcome David as a partner in our firm,” he said. “His values, mindset, talents and appetite for excellence will continue our efforts to build a world-class firm for our clients and employees.”
