His experience includes structuring qualified opportunity zone (QOZ) funds; qualified small business stock; real estate investment trusts (REITs); regulated investment companies; insurance-dedicated investment structures; and cross-border feeder funds designed to accommodate the tax sensitivities of institutional investors, family offices, and private clients.

Before joining McDermott, Mohsen was a transactional tax lawyer at a leading international law firm where he focused on the tax aspects of complex business and investment transactions. He subsequently served as deputy general counsel and managing director at a top-ranked multifamily office with more than $60 billion in assets under management and a $4 billion private capital platform. In that role, he advised high-net-worth individuals, families, and their advisor teams and led the structuring of innovative retail-focused alternative investment products, including semi-liquid funds registered under the Investment Company Act of 1940 (’40 Act) and business development companies.
