CINCINNATI, January 3, 2022 Calfee, Halter & Griswold LLP is pleased to announce the election of Corporate and Finance attorney Patrick D. Hayes to Partner.

Hayes, who serves as Leader of the firm’s Investment Management practice, represents and supports advisers in the development and administration of their compliance programs, including the creation and implementation of written policies and procedures governing all activities of the adviser and any associated funds. His clients include wealth management firms, private equity advisers, family offices, ERISA investment fiduciaries, dual registrants, broker-dealers, cryptotraders, FinTech and Robo-advisers, mutual fund trusts, and institutional equity and fixed income asset managers.

"We are proud to welcome Patrick as a Partner in Calfee’s Corporate and Finance practice group and specifically our Investment Management Practice," said Jennifer L. Vergilii, Co-Chair of Calfee’s Corporate and Finance practice group. "Patrick is an incredibly talented lawyer with keen knowledge and insight, and his business acumen and leadership inspire confidence in clients and colleagues alike."

As a member of Calfee’s Corporate and Finance group, which was recently ranked by Best Lawyers® as the “Top Listed Law Firm” in Ohio for Securities/Capital Markets Law, Hayes also serves as outside general counsel to adviser clients, serving to draft, coordinate and review all legal documents of the adviser, including contracts, fund formation documents, adviser and fund regulatory filings and other related materials.

Hayes conducts due diligence and monitors activities of sub-advisers, third-party managers and relevant service providers, and he assists with matters before the Securities and Exchange Commission (SEC), Commodity Futures Trading Commission (CFTC), Department of Justice (DOJ), Financial Industry Regulatory Authority (FINRA), North American Securities Administrators Association (NASAA), as well as before state securities commissions, attorneys general and local authorities.

"Patrick is an outstanding lawyer and person, and it’s gratifying to all of us at Calfee that he has achieved this career milestone with our firm,” said John A. Mongelluzzo, Partner-In-Charge of Calfee’s Cincinnati office. “Patrick has accomplished so much for his clients and our firm, and we’re excited about his growth potential and future contributions as a Partner.”

In 2020, Hayes launched The Securities Compliance Podcast: Compliance in Context™, co-sponsored by Calfee and the National Society of Compliance Professionals, a nonprofit, membership organization dedicated to serving and supporting compliance professionals in the financial services industry. Hayes designed the podcast as a personal master class for the securities industry’s legal and compliance professionals. With 7,600 listeners in 2021, the podcast was named a “Top 20 Securities Podcast of 2021” by Welp Magazine.

Hayes serves the National Society of Compliance Professionals as a member of the Board of Directors and as a member of the Publications Committee and Regulatory Advisory Committee. He has authored several recent articles for the National Society of Compliance Professionals Currents publication, and he has been selected as a presenter at NSCP's National and Spring Conferences (2019-2021) and at the BDO Annual Private Equity Fund CFO Roundtable in Chicago in December 2021.

The Immediate Past President of the University of Cincinnati Law Alumni Association, Hayes also is a graduate of Class 8 of the Cincinnati USA Regional Chamber's C-Change Leadership Program.

Hayes has been selected for inclusion to The 2022 Best Lawyers in America® for Securities/Capital Markets Law. He also has been selected to the 2022 Ohio Rising Stars list; each year, no more than 2.5% of the attorneys in the state are selected by the research team at Super Lawyers to receive this honor, which recognizes outstanding lawyers who have attained a high degree of peer recognition and professional achievement. Hayes has been recognized by Cincy Magazine as a "Cincy Leading Lawyer" (2020 - 2021), and he was a 2019 "Forty Under 40 Honoree" as recognized by the Cincinnati Business Courier.

Hayes earned his J.D. from the University of Cincinnati College of Law in 2008, where he was inducted into the Order of the Barristers for outstanding ability in appellate advocacy. He earned his B.A., magna cum laude, from the University of Notre Dame in 2005.
