Biography
Age
Susan Lynn Lieberman was born in Dallas, Texas. While public records and various biographical profiles sometimes vary slightly—citing her birth year as 1963, 1964, or 1965—most authoritative sources and historical timelines point to late 1964. As of 2026, she is in her early sixties, though she maintains a highly active and vigorous lifestyle that rivals individuals decades younger.
Height
While her exact medical measurements are not a matter of public record, photographs of Susan standing next to her husband (who is reportedly around 5 feet 7 inches or 5 feet 8 inches) and various other public figures suggest she stands at approximately 5 feet 6 inches tall. Her athletic, lithe build is a direct result of decades of rigorous physical training, road cycling, and endurance sports.
Early Life
Susan grew up in a prominent and well-to-do family in Dallas, Texas. Her father, Dr. Zelig Lieberman, was a highly respected physician, and her mother, Marilyn Elyse Lieberman, managed the household while instilling strong community values in her children. Raised in an affluent neighborhood within a household that maintained deep Jewish roots, Susan was taught early on the importance of tikkun olam—the traditional Jewish concept of repairing the world through social action and charity.
From a very young age, Susan was highly competitive and active. She excelled in tennis, swimming, and track, developing a fierce personal discipline that would later translate into both her business ventures and her athletic achievements as an adult. Alongside her athletic pursuits, she harbored a deep passion for clothing construction, textiles, and design, often sketching out outfits during her teenage years while attending W.T. White High School in Dallas.

Education
Driven by her creative interests and a keen eye for aesthetics, Susan enrolled at Arizona State University (ASU). Unlike many individuals in the tech sphere who pursued engineering, computer science, or finance, Susan followed her authentic passion for commerce and style, graduating with a bachelor’s degree in Fashion Merchandising and Design. Her time at ASU provided her with a strong foundation in both the creative and operational sides of the apparel industry—skills she would later utilize to launch her own luxury brand on the global stage.

Major Career Milestones
Founding the Michael & Susan Dell Foundation

In 1999, utilizing the immense wealth generated by the historic rise of Dell Technologies, Susan and Michael established their eponymous foundation. Unlike traditional charities that merely write checks for galas, Susan insisted on a rigorous, venture-capital approach to philanthropy. Under her strict guidance as Board Chair, the foundation requires measurable outcomes, extensive baseline data, and clear, proven evidence of progress from the organizations it funds. This data-driven, results-oriented model has made the foundation one of the most effective and closely studied philanthropic entities in the world today.
The Launch and Legacy of Phi
Susan did not just want to wear high fashion; she deeply wanted to create it. In 2004, she launched Phi, a luxury womenswear brand named after the golden ratio. Rather than relying solely on her celebrity status, Susan hired acclaimed designer Andreas Melbostad to serve as creative director, ensuring the brand had serious industry credibility.
Phi quickly gained a glowing reputation for its architectural precision, edgy leather outerwear, and modern, matrix-inspired aesthetic. It earned stellar reviews in Vogue and Harper’s Bazaar and opened a stunning flagship boutique in SoHo, New York. However, the 2008 financial crisis devastated the luxury retail sector globally. Recognizing the bleak economic landscape for independent luxury brands, Susan pragmatically chose to shutter the label in late 2009 rather than continually absorb massive corporate losses.
Presidential Appointments and Athletic Advocacy
A lifelong athlete, Susan took her passion for fitness to the absolute extreme by training for competitive triathlons. In 2003, she completed the grueling Ironman World Championship in Kona, Hawaii—a legendary race consisting of a 2.4-mile ocean swim, a 112-mile bicycle ride across lava fields, and a 26.2-mile marathon run. Her immense dedication to health and fitness caught the attention of the White House, and President George W. Bush appointed her to the President’s Council on Physical Fitness and Sports, where she fiercely advocated for childhood health and physical education programs nationwide.
Businesses and Investments
Beyond her stint as the CEO and visionary behind Phi, Susan’s business footprint is heavily intertwined with the Dell Family Office, originally known as MSD Capital (and later structured alongside DFO Management). Established in 1998, this private investment firm securely manages the Dell family’s vast wealth. While Michael Dell and his elite financial managers handle the day-to-day trading and corporate acquisitions, Susan has historically played a significant strategic role in the family’s real estate acquisitions, philanthropic endowments, and investments in health and wellness enterprises.
Main Sources of Income
As a dedicated philanthropist who commits her time to the non-profit sector, Susan Dell does not draw a traditional corporate salary. Instead, her wealth and income are derived from:
- Dell Technologies Stock: The absolute core of the family’s historic fortune.
- MSD Capital Returns: A massive, diversified portfolio spanning public equities, private equity, and commercial real estate (including luxury assets like the Four Seasons Resort Maui).
- Corporate Acquisitions and Mergers: Massive windfalls generated from the strategic mergers, acquisitions, and spin-offs orchestrated by Michael Dell (such as the historic EMC acquisition and VMware spin-off).
Estimated Net Worth
How the Estimate is Derived
Because Susan and Michael Dell operate their finances as a deeply integrated married couple, Susan’s individual net worth is essentially the shared marital wealth of the Dell family. As of 2026, premier financial tracking publications like Forbes and the Bloomberg Billionaires Index place Michael Dell’s net worth well north of $130 billion, often fluctuating between $110 billion and $150 billion depending on tech stock performance and market conditions.
Financial Nuances and Joint Wealth
This vast, astronomical fortune is derived primarily from Michael’s roughly 50% stake in Dell Technologies, alongside the massive assets expertly managed by MSD Capital. While Texas is a community property state (meaning wealth generated during the marriage is generally considered equally owned by both spouses), billionaires of this caliber invariably have complex legal trusts, prenuptial or postnuptial agreements, and intricate family office structures. Therefore, while Susan is effectively a multi-billionaire and one of the wealthiest women in the world, exact figures attributed to her individually are not publicly disaggregated from the family estate.
(Note: Net worth estimates are speculative and based on public market valuations, which fluctuate daily.)
Assets (Homes, Cars, and Investments)
The Dell family portfolio includes some of the most exclusive, heavily guarded, and highly valued real estate in the world.
The Austin “Raptor Residence”
The family’s primary base of operations is a sprawling, highly secure compound nestled in the hills of Austin, Texas, locally dubbed the “Raptor Residence.” Valued in the tens of millions, the massive home reportedly spans roughly 33,000 square feet, sitting on dozens of pristine acres of land. It features state-of-the-art corporate-level security, indoor and outdoor athletic facilities, and extensive manicured grounds.
New York City One57 Penthouse
In 2014, the Dells broke New York real estate records by purchasing a breathtaking 10,923-square-foot duplex penthouse in the elite One57 tower for a staggering $100.47 million. The luxury apartment overlooks Central Park, features unparalleled city views, and serves as the family’s opulent East Coast base.
Hawaiian Retreat
The family also owns a massive, multi-lot compound in the highly exclusive Kukio community on the Big Island of Hawaii. This tropical retreat boasts expansive oceanfront views, severe privacy measures, and serves as a quiet private getaway for the family to escape the public eye.
Regarding cars and private aviation, the family utilizes private jets (often registered through corporate entities or fractional ownership groups) and maintains a fleet of luxury and security vehicles necessary for high-profile billionaires requiring constant protection.
Brand Endorsements
Unlike modern influencers, actors, or celebrities who eagerly monetize their image, Susan Dell does not participate in brand endorsements. During the operational years of her fashion label, Phi, she acted as the primary ambassador for her own brand, but she strictly avoids commercial endorsements for third parties. She prefers to lend her name, image, and considerable influence exclusively to philanthropic causes, educational initiatives, and the Dell Scholars program.
Social Media Presence
Susan Dell maintains a relatively low and fiercely private profile on social media. While she does have verified accounts on platforms like X (formerly Twitter) and LinkedIn, she uses them sparingly. When she does post, it is almost exclusively to highlight the achievements of the Michael & Susan Dell Foundation, advocate for educational equity, or celebrate corporate milestones related to Dell Technologies. She actively protects her family’s privacy, entirely avoiding the oversharing typical of modern celebrity culture.
Awards and Achievements
Susan’s relentless work in philanthropy and public health has not gone unnoticed. Some of her most notable public recognitions include:
- TIME100 Philanthropy List: Recognized alongside her husband for transformative global giving and changing the landscape of education.
- The History-Making Texan Award (2025): Awarded by the Texas State History Museum Foundation for exceptional, generational contributions to the state and the world.
- Presidential Appointee: Honored by serving on the President’s Council on Physical Fitness and Sports.
- Ironman Finisher: A grueling athletic achievement that stands as a permanent testament to her personal discipline and mental fortitude.
Personal Life
Marriage to Michael Dell
Susan Lieberman met Michael Dell on a blind date in Austin, Texas, in the spring of 1988. At the time, Michael was a 23-year-old college dropout whose company, PC’s Limited (soon to be Dell Computer Corp.), was experiencing skyrocketing, unprecedented success. Susan, working in real estate, was unimpressed by the corporate hype and connected with Michael on a deeply personal, human level. They married in October 1989 in a beautiful ceremony. Susan has been repeatedly credited by Michael as the essential stabilizing force in his life, helping him navigate the intense pressures of leading a global tech giant through stock market crashes, intense SEC investigations, and massive corporate buyouts.
Motherhood and Family Values
Together, Susan and Michael have four children: Alexa, Kira, Juliette, and Zachary. Despite their immense, world-class wealth, Susan made it a strict priority to raise her children with a strong work ethic, a sense of grounded reality, and an understanding of the value of money. The Dell children have since grown into adulthood, successfully pursuing their own independent careers in technology, venture capital, and social activism, actively continuing the family’s long legacy of engagement and enterprise.
Philanthropy: A Legacy of Giving
As Board Chair of the Michael & Susan Dell Foundation, Susan has overseen the strategic deployment of more than $2.43 billion to various vital causes globally. The foundation currently manages assets estimated between $5.4 billion and $7.5 billion, making it a colossal force for good.
Dell Scholars Program
One of Susan’s proudest and most successful initiatives is the Dell Scholars Program. Recognizing that low-income, first-generation college students often drop out not due to a lack of intellect, but a severe lack of financial and emotional resources, the program offers a holistic support system. Scholars receive $20,000 in financial aid, a high-end laptop, textbook credits, and critical ongoing mentorship and psychological support to ensure they actually cross the stage and graduate. The program’s graduation rates far exceed the national average for similar demographics.
Healthcare and Dell Medical School
In 2013, the foundation pledged a historic $50 million to establish the Dell Medical School at the University of Texas at Austin. This transformative gift helped create a cutting-edge medical institution focused strictly on redefining community healthcare, advancing medical research, and building inclusive health ecosystems in Central Texas that serve all income levels.
Disaster Relief: Rebuild Texas Fund
When Hurricane Harvey devastated Texas in 2017, completely flooding communities and destroying businesses, Susan and Michael acted immediately. They launched the Rebuild Texas Fund, personally contributing $36 million of their own money with the ambitious goal of raising $100 million for long-term community recovery. Susan was deeply and personally involved in ensuring funds were distributed efficiently to micro-businesses, local schools, and neighborhood healthcare facilities that needed immediate capital to survive.

Lesser-Known Facts
- Competitive Cyclist: Before transitioning to the grueling world of triathlons, Susan was heavily involved in competitive road cycling, often riding dozens of miles a day.
- Design Background: While Phi is her most famous brand, she actually started three different distinct fashion labels throughout her career before refining her vision.
- Data Geek: Despite her fashion and creative background, colleagues frequently note that Susan is incredibly data-driven, often demanding strict metric reports, spreadsheets, and verifiable progress from the charities her foundation supports.
