There is no verified direct business, personal, family, or board relationship between John Grayken and Lynn Good in the major corporate disclosures and reliable public records reviewed. The clearest documented link is indirect: Grayken began his career at Morgan Stanley decades ago, while Good joined Morgan Stanley’s board of directors in 2025.
That distinction matters. John Grayken built his career in private equity and distressed investing through Lone Star Funds, while Lynn Good spent much of her career in accounting and the regulated utility industry, eventually leading Duke Energy. Their careers touch the same broad world of major U.S. corporations and finance, but the available evidence does not show that they have worked together.
What Is the Connection Between John Grayken and Lynn Good?
The available evidence does not establish a direct relationship between John Grayken and Lynn Good. Neither Lone Star Funds’ current leadership information nor Good’s recent corporate disclosures identifies the other person as a colleague, business partner, fellow director, investor, or adviser.
There is, however, an interesting Morgan Stanley connection across different periods.
Forbes’ detailed profile of Grayken reports that after earning his MBA from Harvard Business School in 1982, he entered investment banking at Morgan Stanley.
Good’s connection is much more recent. Morgan Stanley announced on June 16, 2025, that she had been elected to its board of directors effective July 18, 2025. The firm’s 2026 materials continue to identify her as a board member.
This creates an institutional overlap, but not a demonstrated personal connection. Grayken’s Morgan Stanley employment occurred many years before Good joined the board.

Who Is John Grayken?
John P. Grayken is the founder and chairman of Lone Star Funds, an investment organization best known for investing across private equity, credit, real estate and opportunistic assets.
Lone Star’s current leadership page says Grayken has been investing for the organization for more than 30 years. Since the first fund was established in 1995, Lone Star says its funds have accumulated approximately $96 billion in aggregate capital commitments.
Grayken also founded Hudson, the asset-management business that supports Lone Star’s investment activities. According to Lone Star, Hudson has advised on approximately 1.10 million assets with an aggregate purchase price of about $284 billion.
His influence over the organization remains significant. A May 26, 2026 European Commission merger decision concerning Lone Star Fund XII described Lone Star as being controlled by John Grayken of Ireland.
Grayken’s Early Career
Grayken earned a bachelor’s degree in economics from the University of Pennsylvania and an MBA from Harvard Business School. A Wharton profile also confirms those academic credentials.
According to Forbes, he entered investment banking at Morgan Stanley after Harvard before moving into real estate investing associated with Texas investor Robert Bass. His experience buying and restructuring troubled assets eventually became central to the investment model for which Lone Star became known.
The modern Lone Star organization is no longer run solely as a founder-led operation. Its leadership page lists Donald J. Quintin as chief executive officer and global president, while Grayken remains chairman.
Who Is Lynn Good?
Lynn J. Good is an American business executive best known for her long tenure at Duke Energy, where she served as chief executive officer from 2013 until 2025.
Good held several senior finance positions before becoming CEO. Morgan Stanley’s biography of her records roles including executive vice president and chief financial officer of Duke Energy from 2009 to 2013 and earlier financial leadership positions at Cinergy Corporation.
Her professional background also includes accounting. She spent many years at Arthur Andersen, eventually becoming an audit partner, and served as an audit partner at Deloitte & Touche before moving fully into the energy industry.
Lynn Good’s Retirement From Duke Energy
Good is no longer Duke Energy’s CEO.
Duke Energy announced in January 2025 that Harry Sideris would succeed her as president and chief executive officer on April 1, 2025. Good retired from both her management role and the Duke Energy board on that date after more than two decades with the company and nearly 12 years as CEO.
As of 2026, Duke Energy is led by Sideris, not Good.
What Is Lynn Good Doing Now?
Good has continued to hold significant corporate governance positions after leaving Duke Energy.
Morgan Stanley elected her to its board effective July 18, 2025. The bank highlighted her experience in executive management, finance, accounting and regulated industries when announcing the appointment.
She also remains a director of The Boeing Company. Boeing’s 2026 proxy statement identifies Good as an independent director who has served on its board since 2015. It lists her as chair of Boeing’s Compensation Committee and a member of its Audit Committee.
Boeing’s April 17, 2026 shareholder-vote filing confirms that she was elected as a director at the company’s 2026 annual meeting.
The same Boeing proxy also identifies Morgan Stanley as another current public-company directorship held by Good.
The Morgan Stanley Link Explained
Morgan Stanley is the strongest identifiable institutional link between John Grayken and Lynn Good, but the timing shows why it should not be exaggerated.
Grayken’s association with Morgan Stanley dates to the beginning of his career. Forbes reports that he joined its investment-banking business after graduating from Harvard Business School in 1982.
Good joined Morgan Stanley’s board more than four decades later, in July 2025. She was appointed after retiring from Duke Energy and brought experience in finance, accounting, corporate governance and management of a large regulated company.
There is no evidence in these sources that Grayken had a role in Good’s appointment, that the two served at Morgan Stanley simultaneously, or that Morgan Stanley created a direct professional relationship between them.
It is therefore more accurate to describe Morgan Stanley as an institutional overlap in their career histories, rather than evidence of a partnership.

How Their Business Careers Differ
Grayken and Good reached prominent positions through very different sectors.
John Grayken: Private Capital and Opportunistic Investing
Grayken’s career centers on deploying investment capital. Lone Star invests globally across areas including real estate, corporate equity, credit and other financial assets. The firm has historically been associated particularly closely with opportunities created by financial distress, troubled assets and market dislocations.
The scale of the organization is substantial. Lone Star currently reports roughly $96 billion in aggregate capital commitments since the creation of its first fund.
Grayken therefore built his career primarily as an owner, investor and private-equity founder.
Lynn Good: Utilities and Corporate Management
Good developed through accounting, financial management and utility operations.
She became Duke Energy’s CEO in July 2013 and later served as chair. By the time she retired in April 2025, she had spent more than two decades with Duke Energy and its predecessor environment.
Her post-Duke career has moved further toward board governance through positions at Boeing and Morgan Stanley.
Good’s career is therefore better characterized as that of a corporate executive, financial leader and director, rather than a private-equity investor.
Is Lone Star Funds Connected to Duke Energy?
No major direct relationship between Lone Star Funds and Duke Energy emerges from the corporate information that establishes Grayken’s and Good’s careers.
That point is particularly important because the words “Lone Star” appear frequently in energy-related contexts, especially in Texas. Not every company or project carrying the words Lone Star is related to John Grayken’s Lone Star Funds.
Grayken’s Lone Star is a private investment organization. Duke Energy, meanwhile, is a publicly traded U.S. energy company. A similarity in company names appearing in energy, infrastructure or Texas-related documents should not be interpreted automatically as evidence of a Grayken-Good connection.
Where John Grayken and Lynn Good Stand in 2026
Their current positions make the separation between their careers particularly clear.
Grayken remains founder and chairman of Lone Star Funds. Lone Star currently identifies Donald Quintin as its CEO and global president, while Grayken retains the chairman position.
Good has retired from Duke Energy and now appears prominently in corporate governance. She serves on the boards of Morgan Stanley and Boeing, with 2026 filings confirming those positions.
So, as of September 2026, there is no verified evidence that the two executives have joined the same board, founded a business together, participated in a disclosed joint investment, or developed another publicly documented direct relationship.
Why the Distinction Matters
Searches combining the names of two high-profile business figures can create the impression that a relationship already exists. That is not always the case.
With John Grayken and Lynn Good, the reliable evidence supports three separate facts:
- Grayken is the founder and current chairman of Lone Star Funds.
- Good is the former Duke Energy CEO and currently serves on major corporate boards including Morgan Stanley and Boeing.
- Both have connections to Morgan Stanley, but during very different periods and in very different capacities.
Anything stronger, such as describing them as business partners, close associates or joint investors, would require evidence that is not present in the authoritative sources reviewed.
