Natasha Kassian has over 30 years of buy-side experience providing legal and compliance guidance to registered investment advisers across a broad range of products, asset classes, investment strategies, and jurisdictions. She has served in roles including General Counsel and Chief Compliance Officer for firms that manage hedge funds, private equity funds, venture funds, retail and institutional separately managed accounts, mutual funds, and exchange-traded funds.
Ms. Kassian has extensive experience responding to examinations and inquiries by regulators in the US, EU, EMEA, and APAC, and is a recognized investment management compliance expert.

In her consulting practice, Ms. Kassian provides legal and compliance services to a variety of investment adviser clients. Prior to beginning her consulting practice, Ms. Kassian worked in-house for leading hedge funds including Citadel and Millennium in Chief Compliance Officer roles amongst others. Prior to that she worked in the asset management divisions of major investment banks including UBS and Morgan Stanley.

Ms. Kassian also clerked for the Honorable Fred I. Parker of the United States Court of Appeals for the Second Circuit. Her dual-major undergraduate degree is in Accounting and Economics. After clerking she began her career in the investment management department of Paul, Weiss, Rifkind, Wharton & Garrison.

In 2004, when the SEC first adopted compliance rules under the Investment Advisers Act and Investment Company Act, Ms. Kassian shifted her legal practice to focus on buy-side compliance and prepared an array of clients for the implementation of the new rules. In subsequent roles, Ms. Kassian created new or enhanced compliance programs for over a dozen registered investment advisers. She has drafted and implemented over a hundred compliance policies and procedures and developed numerous surveillance and reporting systems for internal monitoring and to comply with regulatory and exchange requirements in multiple jurisdictions. In 2012, when the Dodd-Frank Act eliminated the private adviser exemption, Ms. Kassian again refocused her practice to include hedge funds, private equity funds, and venture funds, and expanded her practice outside the US.

Ms. Kassian has extensive experience performing mock exams and audits, preparing compliance program assessment reports, and conducting internal investigations and interviews.
