Peter Amory Weinberg (born c. 1957) is an American businessman and investment banker who co-founded Perella Weinberg Partners, a financial services firm providing advisory and asset management services, alongside merger specialist Joseph Perella in 2006. Before establishing his own firm, Weinberg spent nearly two decades at Goldman Sachs, where he rose through the ranks to become a partner and head of the firm's investment banking division in Europe. A member of the Weinberg banking dynasty — his grandfather Sidney Weinberg and father John L. Weinberg both served as senior partners of Goldman Sachs — Peter Weinberg carved a distinct path by departing the family firm to build an independent advisory boutique. As founding partner and chairman of Perella Weinberg Partners, he has overseen the firm's growth from a startup advisory practice into a publicly traded company listed on the NASDAQ. He also served as the firm's chief executive officer from February 2019 to January 2023. In early 2026, it was reported that Perella Weinberg Partners planned to name Peter Weinberg as CEO once again.

Early Life

Peter Amory Weinberg was born circa 1957 in Rye, New York, into one of the most prominent families in American finance. His grandfather, Sidney Weinberg, was a legendary figure on Wall Street who led Goldman Sachs as senior partner for nearly four decades, from 1930 until his death in 1969. Sidney Weinberg, often referred to as "Mr. Wall Street," transformed Goldman Sachs from a modest trading firm into one of the world's premier investment banks. Peter's father, John L. Weinberg, continued the family legacy by serving as senior partner and co-chairman of Goldman Sachs from 1976 to 1990.

Growing up in Rye, a suburban community in Westchester County, New York, Peter Weinberg was immersed in a household where finance and business leadership were central topics. The Weinberg family's deep ties to Goldman Sachs — spanning three generations — placed considerable expectations on the younger generation. His cousin, John S. Weinberg, also went on to serve in senior leadership positions at Goldman Sachs, eventually becoming co-head of the investment banking division.

Despite the weight of the family name and its close association with Goldman Sachs, Peter Weinberg pursued his own educational and professional trajectory. He chose to attend college on the West Coast, a geographic departure from the East Coast financial establishment in which he was raised.

Education

Weinberg attended Claremont McKenna College in Claremont, California, where he earned a Bachelor of Arts degree. Claremont McKenna, known for its emphasis on leadership, economics, and government, provided Weinberg with an undergraduate foundation outside the traditional Ivy League pipeline that was common among Wall Street families of his era. Weinberg has maintained a connection to the institution throughout his career, serving on the advisory board of the college's Kravis Leadership Institute.

Following his undergraduate studies, Weinberg enrolled at Harvard Business School, where he earned a Master of Business Administration (MBA) degree. The combination of a liberal arts education at Claremont McKenna and graduate business training at Harvard positioned Weinberg to enter the investment banking profession, where he would spend the entirety of his career.

Career

Goldman Sachs (1988–2005)

Peter Weinberg joined Goldman Sachs in the late 1980s, entering the firm that his grandfather and father had helped build into a global financial institution. Over the course of nearly two decades, Weinberg rose through the ranks of the firm's investment banking division.

Weinberg was named a partner of Goldman Sachs, a distinction that placed him among the firm's most senior executives. He eventually assumed the role of head of investment banking for Goldman Sachs in Europe, based in London. In this capacity, he oversaw the firm's European advisory and capital markets operations, managing relationships with major corporate clients and governments across the continent.

During his tenure in London, Weinberg was involved in some of Goldman Sachs' most significant European transactions. His role placed him at the center of cross-border mergers and acquisitions activity during a period of substantial consolidation across European industries. He also served as a member of the firm's partnership committee and European management committee.

Despite his success and the deep family connection to Goldman Sachs, Weinberg reportedly found that the increasing size and complexity of the firm — which had transitioned from a private partnership to a publicly traded company in 1999 — created an environment that was less aligned with his preferences for client-focused advisory work. As he later described in a conversation at the Wharton School of the University of Pennsylvania, a large organization could become "a velvet coffin, providing a cozy and lucrative home but work that is no longer" fulfilling in the same way.

Weinberg departed Goldman Sachs in 2005, after approximately eighteen years at the firm.

Founding of Perella Weinberg Partners (2006)

In 2006, Peter Weinberg co-founded Perella Weinberg Partners with Joseph Perella, a veteran dealmaker who had previously been a senior figure at First Boston, Wasserstein Perella & Co., and Morgan Stanley. The pairing brought together two complementary skill sets: Perella's reputation as one of Wall Street's foremost mergers and acquisitions specialists, and Weinberg's experience in global investment banking leadership and client management.

The firm was established with the dual mandate of providing independent financial advisory services — principally in mergers and acquisitions, restructuring, and capital markets advisory — as well as alternative asset management services. By operating as an independent advisory firm without the conflicts of interest inherent in large, diversified financial institutions, Perella Weinberg Partners positioned itself in the growing boutique advisory segment that had gained prominence in the years following the 2000s wave of financial industry consolidation.

In a 2012 discussion at Wharton, both Perella and Weinberg reflected on the dynamics of their partnership and the founding of the firm. Weinberg noted the importance of building a firm that prioritized client relationships and independent advice, values he felt had been diluted at larger institutions. The two founders described their complementary roles: Perella focused heavily on deal execution and transaction advisory, while Weinberg concentrated on the firm's overall strategy, management, and business development.

The timing of the firm's founding proved both challenging and opportunistic. Established just prior to the financial crisis of 2007–2008, Perella Weinberg Partners navigated the turbulence of the global financial meltdown while simultaneously benefiting from the demand for independent, conflict-free advisory services during a period when trust in large Wall Street banks had eroded. The firm grew its restructuring practice substantially during this period, as distressed companies sought advisory services for debt restructuring, bankruptcy proceedings, and asset sales.

Growth and Public Listing

Under Weinberg's leadership as founding partner, Perella Weinberg Partners expanded its operations significantly in the years following its founding. The firm built out its advisory capabilities across sectors and geographies, while also growing its asset management business to manage billions of dollars in client assets.

Perella Weinberg Partners eventually pursued a public listing, becoming a publicly traded company on the NASDAQ stock exchange under the ticker symbol PWP. The transition to a public company represented a significant milestone for a firm that had been founded as a private partnership.

In the fourth quarter of calendar year 2025, Perella Weinberg Partners reported better-than-expected revenue results, though sales declined by 2.9 percent compared to the prior period.

CEO Tenure (2019–2023) and Return

In February 2019, Peter Weinberg assumed the role of chief executive officer of Perella Weinberg Partners, adding operational leadership responsibilities to his founding partner role. He served as CEO until January 2023, when he transitioned the role to Robert Steel.

Following Steel's tenure as CEO, it was reported in early 2026 that Perella Weinberg Partners planned to name Peter Weinberg as its chief executive officer once again, with Steel set to depart the role. This planned return to the CEO position underscored Weinberg's continued central role in the firm's leadership and strategic direction two decades after its founding.

Perella Weinberg Partners Trial (2025)

In March 2025, the Financial Times reported on a trial involving Perella Weinberg Partners that brought to light internal disputes among senior bankers at the firm. The trial involved allegations that a senior rainmaker at the firm had plotted to start a rival enterprise, raising questions about whether the firm had been harmed by the alleged actions. A judge involved in the proceedings raised questions about the extent of any damage to the firm. The trial provided a rare public window into the competitive dynamics and internal tensions that can characterize elite advisory firms.

Personal Life

Peter Weinberg is married to Deborah L. Weinberg. The couple has three sons.

The Weinberg family has been active in philanthropic endeavors, particularly in the area of healthcare. In 2013, Columbia University Irving Medical Center announced it had received $7 million from the Weinberg family to launch the Weinberg Family Cerebral Palsy Center, a specialized facility dedicated to the treatment and study of cerebral palsy. In October 2023, it was announced that the center had received an additional $6.5 million gift to expand its operations as it entered its second decade, enabling the center to broaden its clinical services, research programs, and patient support initiatives.

Weinberg has served on the board of overseers and managers of Memorial Sloan Kettering Cancer Center, one of the world's leading cancer treatment and research institutions. He has also served as a trustee of King's Academy in Madaba, Jordan, an educational institution modeled on American preparatory schools.

Board Memberships and Affiliations

In addition to his roles at Perella Weinberg Partners, Weinberg has held positions on several institutional boards. He has served on the advisory board of the Kravis Leadership Institute at Claremont McKenna College, his undergraduate alma mater. He has been a member of the board of overseers and managers of Memorial Sloan Kettering Cancer Center. He has also served on the board of trustees of King's Academy in Jordan.

Weinberg has been a member of the Business-Higher Education Forum (BHEF), an organization composed of senior business and higher education leaders focused on workforce development and education policy.

He has made multiple appearances as a commentator on CNBC, discussing financial markets, investment banking, and economic conditions.

Legacy

Peter Weinberg's career represents both a continuation of and a departure from his family's deep legacy in American finance. As a third-generation Goldman Sachs partner, he carried forward the Weinberg name in investment banking while simultaneously charting an independent course by leaving the firm to co-found Perella Weinberg Partners. The decision to depart Goldman Sachs — the institution most closely associated with his family for over seven decades — to create an independent advisory firm demonstrated a willingness to step beyond the established family path.

The founding and growth of Perella Weinberg Partners contributed to the broader trend of independent advisory firms that reshaped the investment banking landscape in the first two decades of the 21st century. Alongside other boutique firms such as Evercore, Lazard, Moelis & Company, and PJT Partners, Perella Weinberg Partners became part of an industry segment that competed for major advisory mandates with the bulge-bracket banks that had historically dominated the field.

The Weinberg family's philanthropic contributions, particularly the establishment and expansion of the Weinberg Family Cerebral Palsy Center at Columbia University, represent a significant commitment to medical research and patient care. The center's launch with $7 million in 2013 and its subsequent $6.5 million expansion in 2023 — totaling $13.5 million in gifts — have created a dedicated facility for cerebral palsy treatment and research at one of the nation's leading academic medical centers.

The Weinberg banking dynasty — spanning Sidney Weinberg, John L. Weinberg, Peter Weinberg, and his cousin John S. Weinberg — represents one of the longest-running family legacies in the history of American investment banking. Peter Weinberg's career, with its combination of institutional pedigree at Goldman Sachs and entrepreneurial initiative at Perella Weinberg Partners, illustrates the evolution of the advisory profession from the partnership-era Wall Street of his grandfather's day to the modern landscape of publicly traded financial services firms.
